<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=81</link>
<description><![CDATA[Business processes are conventionally modeled as monolithic flows that capture the desired business logic. However, developing process flows is challenging. Because a flow specifies what its participants should do, it restricts the autonomy of its participants, thus limiting their ability to exploit opportunities or accommodate exceptions according to their business preferences. We take a dual perspective wherein business processes are modeled as compositions of (instantiated) business protocols. Each business protocol specifies interactions among its partners; each protocol serves a unique business purpose, e.g., processing a payment or shipping an item. Thus, modularizing a monolithic business process via business protocols allows clear separation of concerns for modeling and enacting the process. We develop an approach in which protocols are compiled into local skeletal flows for each participant that can be fleshed out with local business logic as needed. Such flows are naturally distributed but can be enacted using commercial business flow engines. Thus, our protocol-based approach combines the benefit of improved modeling with simplified implementations.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314721">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[Web services technologies are emerging as a new approach for supporting e-Science and e-Engineering by providing access to heterogeneous computation resources and integration of distributed scientific applications. In this paper, we propose a web portal architecture that enables end users to access the distributed application through the web interface and to compose new tasks by integrating a set of high level web services provided by portal developers. The portal design demonstrates that flexibility, reusability and interoperability can be provided for both end users and portal developers by using semantic web services technologies. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314964">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[Probabilistic duration representations can be used to forecast the response time of (composite) web services, based on empirical data of past executions or calculated from control flow structures. The capability to choose the fastest among similar services or to optimize services based on probable process execution times are only two possible application areas. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314963">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[We show how a standard Grid service architecture can be improved by interposing a policy enforcement engine between a calling application and the relative client stubs. Therefore, with our solution selection and invocations are not hard-coded into client applications but (declaratively) defined and enforced outside the clients; therefore they can be (de)activated and modified on-line. Our policies are specified using the PDL language which supports specification of preferences and prohibitions in the routing of remote invocations to Web services. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314961">buy now</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=800</link>
<description><![CDATA[With the advancement of web services technologies, on-line businesses have the ability to offer their capabilities to larger, lesser known communities of potential collaborators. Universal Description, Discovery, and Integration (UDDI) specification and supporting technologies support open frameworks for businesses to store, advertise and retrieve pertinent services. Many researchers investigate approaches that ubiquitously create higher-level processes by composing services discovered in and retrieved from UDDI registries. However, there are few studies that consider the impact of registry performance on future service automation. This work focuses on evaluating the performance of UDDI registries considering variability and concurrent load of publish and inquiry requests. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314962">buy now</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=798</link>
<description><![CDATA[Web Services and Service Oriented Architecture (SOA) represent a radical departure from traditional monolithic, tightly bound, customized applications with proprietary interfaces. Their range however is limited as yet by the very structure and standardization which support their interoperability. While they are able to support heterogeneity of technical components, their ability to support complex business interactions has yet to mature. This poster summarizes research in progress which asks how might the Web Services model be mapped to other kinds of IT services and extended to account for services of greater human and organizational complexity through their lifecycle. The research proposes the construction of a generic IT service model and a taxonomy IT services to provide a frame of reference for analysis and evaluation for the extension of the Web Services model and for a transition to a service oriented view of IT. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314960">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[This study introduces a sound-based mobile payment system as a wireless web service. Using a mobile phone for payment for mobile commerce is essential for its success. The proposed system will use sound that is generated from the existing mobile phone and the sound can be recognized by the existing credit card reader of the shop with an installation of an ordinary microphone and simple software to process sound input. This system is a better system since it doesn't require customers to buy a new mobile phone and the cost for the microphone and the software is very low. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314958">buy now</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=797</link>
<description><![CDATA[A fundamental issue of human-centered coordinating services in Ubiquitous Computing is concerned with dynamic service coordination according to users' intensions. How can we coordinate the services to assist the user in receiving a coordinated service to maximize the user's satisfaction in an environment? In order to solve this issue, we have been developing a sort of agent-based coordination framework, called "location-mediated agent coordination," that orchestrates Web Services embedded in the real world and Web Services on the Internet. In this paper, we show a prototype application of the framework, context-aware information assist services in a museum. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314959">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[This paper presents a model which combines the processing power of parallel computation with the ease of web service usage. In this model, parallel programming environment can be embedded in a visual environment. Parallelization of Web Services is provided by using multi threading technology with dataset parameters.

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=95</link>
<description><![CDATA[Next-generation Government Information Systems will integrate large amounts of heterogeneous data sources located on distributed networks like the Internet. We present Net Traveler which is a framework for web services collaboration, orchestration and choreography in peer-to-peer autonomic environments. The main feature of our new approach is the elimination of a central coordination site running the queries and the autonomic query execution. Moreover, control information is embedded with the request for data, and also with the partial results in an XML document. This XML document indicates the next service to be requested, the target site (if known) and how should it process any partial results. We present the architecture, the ideas behind it, a prototype, and a performance study to validate this framework. This study shows this framework to be flexible, scalable and efficient for the web services collaboration in electronic government applications.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314717">buy now</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=98</link>
<description><![CDATA[The functionality of applications is increasingly being made available by services. General concepts and standards like SOAP, WSDL, and UDDI support the discovery and invocation of single web services. State-of-the-art process management is conceptually based on a centralized process manager. The resources of this coordinator limit the number of concurrent process executions, especially since the coordinator has to persistently store each state change for recovery purposes. In this paper, we overcome this limitation by executing processes in a peer-to-peer way exploiting all nodes of the system. By distributing the execution and navigation costs, we can achieve a higher degree of scalability allowing for a much larger throughput of processes compared to centralized solutions. This papers describes our prototype system OSIRIS, which implements such a true peer-to-peer process execution. We further present very promising results verifying the advantages over centralized process management in terms of scalability.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314720">buy it</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=789</link>
<description><![CDATA[Web services will only have advantages over existing technologies if the service binding can be performed dynamically. However, existing service description languages do not contain enough information for a computer agent to do the selection automatically during runtime on behalf of the user. This results from the fact that in most approaches the offer description language doubles as a request language, which prevents the requestor from a precise formulation of requests and preferences. Therefore, in this paper, we emphasize the need for a distinguished service request language that allows to capture all of the requestor's preferences. We present a concrete technique to represent such preference-containing requests, which is based on fuzzy object sets. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314822">buy now</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=790</link>
<description><![CDATA[Preserving privacy during Web transactions is a major concern for individuals and organizations. One of the solutions proposed in the literature is to maintain anonymity through group cooperation during Web transactions. The lack of understanding of incentives for encouraging group cooperation is a major drawback in such systems. We propose an anonymizing club mechanism, and sequential economic strategy for trusted collaboration. We model the individual transactions as a Prisoners' Dilemma, where two players either cooperate or defect while maintaining each other's anonymity. The activities of the participants over a series of transactions can be modeled as a sequential repeated game. We determine conditions to ensure cooperation among the participants in the sequential repeated game, even if defecting is a dominant strategy in each individual Prisoners' Dilemma game. Our results show that by adopting an appropriate initiation fee and adequate fine for malicious behavior, both enforced through a trusted central authority, we can sustain cooperation in the proposed anonymizing club mechanism. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314823">buy now</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=761</link>
<description><![CDATA[This article presents a theoretical framework distinguishing four systematically different levels of Web Service technology adoption. Based on Swanson's IS innovation theory the conjecture is made that each level of Web Service technology adoption has important differences in adoption requirements and the potential outcomes. The framework is intended to be a conceptual basis for methods to evaluate Web Service technology adoption and may consequently help devise strategies to effectively adopt Web Service technology. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314996">buy now</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=762</link>
<description><![CDATA[Interoperability refers to the ability of software and hardware on multiple machines from multiple vendors to communicate with each other without significant changes on either side. Web services streamline enterprise application integration by making it easier to tie applications running on heterogeneous platforms together helping them communicate correctly, effectively and at reduced cost. The difficulty of integration is a function of the level of interoperability between the applications being integrated. Even though there are established standards for web services messaging (SOAP), description (WSDL) and discovery and registry (UDDI), custom implementations of these protocols by individual vendors has led to various interoperability issues. Web Services Interoperability Organization (WS-I) recently released Basic Profile 1.0, addressing the interoperability issues with core web services standards. In this paper, we look at some of the key web services interoperability issues pointed out by practitioners and critically examine how Basic Profile 1.0 addresses them. Further we also examine some limitations of the profile. We conclude by evaluating a popular web services implementation against the profile and present our observations. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314719">buy now</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=107</link>
<description><![CDATA[We argue that essential facets of web services, and especially those useful to understand their interaction, can be described using process-algebraic notations. Web service description and execution languages such as BPEL are essentially process description languages; they are based on primitives for behaviour description and message exchange which can also be found in more abstract process algebras. One legitimate question is therefore whether the formal approach and the sophisticated tools introduced for process algebra can be used to improve the effectiveness and the reliability of web service development. Our investigations suggest a positive answer, and we claim that process algebras provide a very complete and satisfactory assistance to the whole process of web service development. We show on a case study that readily available tools based on process algebra are effective at verifying that web services conform their requirements and respect properties. We advocate their use both at the design stage and for reverse engineering issues. More prospectively, we discuss how they can be helpful to tackle choreography issues.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314722">buy now</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=110</link>
<description><![CDATA[This paper presents a novel web-based service-oriented framework to support collaborative product commerce. The framework coordinates processes to design and manufacture a product in a loosely coupled environment using Web services. We have developed a service model using OWL. It provides facilities for companies to discover services that other companies provide. Choreography of Web services is achieved using the process grammar. Usage of Process Grammar helps to configure processes dynamically, facilitating collaboration among companies. The framework, therefore, provides a truly distributed architecture for management of service composition and inter-operation, lending a unique functionality to the framework.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314723">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[The emergence of Web services represents a significant advance in the continuing evolution of e-business. In order to fully explore business opportunities provided by this paradigm, it is important to track its utilization. This can be done through the use of logging facilities. However, current Web logging approaches do not contemplate Web services utilization. This paper presents a Web services logging architecture based on SOAP intermediaries that captures comprehensive services usage information, which can be explored to improve B2B and B2C transactions by providing feedback on customer electronic behavior.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314724">buy now</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=763</link>
<description><![CDATA[This paper discusses a solution based on Web services and Service Oriented Architecture involving interorganizational information systems in the context of multi-channel integration in retailing industry. Distribution intensive industries such as retailing have seen a proliferation of distribution channels. This is in part triggered by the intense competition as well as the retailers' drive to reach the customers through all possible channels. As the number of channels for a retailer increases, managing the dynamics of customer behavior in the multi-channel environment becomes complex. Customers have an option of interacting with retailers across a number of channels. Acquiring and retaining customers requires that relationship management applications should be able to accommodate the various channels. In this paper, we provide an overview of the benefits of using Web services in multi-channel integration and related retail processes. We propose a reference service oriented architecture for usage of Web services involving inter and intra company systems for multi-channel integration. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314725">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[Asynchronous interactions are becoming more and more important in the implementation of complex B2B Web applications. This paper addresses correlation and coordination issues involved with asynchronous Web services, by studying different mechanisms and metadata structures for supporting them; in addition, several interaction patterns for building asynchronous computations are discussed, and the trade-offs between the various patterns are shown. In conclusion, we illustrate the use of asynchronous Web services in the context of some concrete B2B applications.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314726">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[Web services promise to allow businesses to adapt rapidly to changes in the business environment, and the needs of different customers. However, the rapid introduction of new services paired with the dynamicity of the business environment also leads to undesirable interactions that negatively impact service quality and user satisfaction. In this paper, we propose an approach for modeling such undesirable interactions as feature interactions. Our approach for detecting interactions is based on goal-oriented analysis and scenario modeling. It allows us to reason about feature interactions in terms of goal conflicts, and feature deployment. Two case studies illustrate the approach. The paper concludes with a discussion, and an outlook on future research. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314727">buy now</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=766</link>
<description><![CDATA[A conversation protocol is a top-down specification framework which specifies desired global behaviors of a web service composition. In our earlier work [A formalism for specification and verification of reactive electronic services] we studied the problem of realizability, i.e., given a conversation protocol, can a web service composition be synthesized to generate behaviors as specified by the protocol. Several sufficient realizability conditions were proposed in [A formalism for specification and verification of reactive electronic services] to ensure realizability. Conversation protocols studied in [A formalism for specification and verification of reactive electronic services], however, are essentially abstract control flows without data semantics. This paper extends the work in [A formalism for specification and verification of reactive electronic services] and achieves more accurate analysis by considering data semantics. To overcome the state-space explosion caused by the data content, we propose a symbolic analysis technique for each realizability condition. In addition, we show that the analysis of the autonomy condition can be done using an iterative refinement approach. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314728">buy now</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=767</link>
<description><![CDATA[The ultimate target of business to business (B2B) integration and deployment is complete business process automation within and between enterprises with no human intervention. From a business point of view, negotiation is the main mechanism that modern enterprises use to achieve targets that maximise their profits. This paper proposes an automated B2B negotiation solution: the implementation of semantic-enabled machine versus machine business negotiation as a web service. We argue that the shift from human vs. human to machine vs. machine business negotiation is facilitated by using semantic web technology implemented with web services. The negotiation process in this work is designed for multiple machines (a minimum of 3 computers), using a negotiation algorithm that emulates the behaviour of human business negotiations. Possible development directions are brought forward in the paper's conclusion. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314729">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[We present the Web Service Description Framework (WSDF), which provides both a representation mechanism and a runtime system architecture for semantically enriched Web Services. We analyze existing languages such as BPEL4WS and OWL-S before addressing their deficiencies in our proposal. Our approach allows a client to invoke a service based solely on a shared ontology, i.e. without prior knowledge on the API, providing an important building block towards a global, flexible information infrastructure. Another main point is that WSDF can be applied to clients and services written in a conventional object oriented programming language. This is achieved by lifting datastructures to an ontology level in which rich logical statements about services can be formalized. We also present a detailed system architecture that covers planning, invocation, and the automatic processing of the service results, which is accomplished using the observer design pattern and by asserting the result in the respective model. Furthermore, the required annotations can be specified conveniently by placing comments in the source code. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314730">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[In this paper, we present a novel approach for specification of invocable semantic web resources in a unified manner. Our approach enables specification of web services, composite web services, web pages and web sites with one single process description language in a unified manner. The basic idea behind our work is, that different types of invocable web resources differ mainly in the ommunication protocol and message formats. The language abstracts from various communication protocols and message formats and hence enables modeling of business logic without worrying much about technical details. Our approach in contrast to existing annotation techniques does not enforce the providers to modify their web resources. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314731">buy now</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=784</link>
<description><![CDATA[Structured Financial Messaging Solution (SFMS) is a secure and common messaging solution that serves as the basic platform for intra-bank and inter-bank applications in the Indian financial sector. SFMS connects around 25 banks, with 500 branches each on average, spread across the length and breadth of the country. SFMS was envisaged in 1999 with MQSeries as the Messaging oriented Middleware. In this paper, we discuss how the middleware in SFMS has evolved from a proprietary messaging middleware to an open middleware to handle the ever-increasing demands of the Indian financial service industry. SFMS has evolved from being a CUG application to being an open system that can be used by any of the bank's strategic business partners. The paper evaluates the technologies at each stage of SFMS transition and discusses how the then-existing anomalies have been removed and highlights the power of Web services in achieving Straight Through Processing, across various players of financial system. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314792">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[WSLAs can be viewed as describing the service aspect of web services. By their nature, web services are distributed. Therefore, integrating support code into a web service application is potentially costly and error prone. Viewed from this AOP perspective, then, we present a method for integrating WSLAs into code generation using the AXpect weaver, the AOP technology for Infopipes. This helps to localize the code physically and therefore increase the eventual maintainability and enhance the reuse of the WSLA code. We then illustrate the weavers capability by using a WSLA document to codify constraints and metrics for a streaming image application that requires CPU resource monitoring.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314732">buy now</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=131</link>
<description><![CDATA[There is a growing demand for provisioning of different levels of quality of service (QoS) on scalable Web servers to meet changing resource availability and satisfy different client requirements. The proportional differentiation model is getting momentum because of its fairness and differentiation predictability. It states that QoS of different traffic classes should be kept proportional to their pre-specified differentiation parameters, independent of the class loads. In this paper, we present a processing rate allocation scheme for providing proportional response time differentiation on Web servers. A challenging issue is how to achieve processing rates for different request classes in the implementation. We propose a process allocation strategy, which dynamically and adaptively changes the number of processes allocated for handling different request classes while ensuring the ratios of process allocation specified by the processing rate allocation scheme. We implement the process allocation strategy at application level on Apache Web servers. Experimental results show that the processing rate can be achieved by the adaptive process allocation strategy and the Web servers can provide predictable and controllable proportional response time differentiation.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314733">buy now</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=132</link>
<description><![CDATA[Enterprise information systems are currently developed as Web-based applications in the service-oriented architecture style, which is implied by the stack of Web services standards. One of the most critical aspects in enterprise information systems is to maintain their continuous operation as long as possible. Conventional service invocation mechanism identifies Web services with similar signatures found by a service discovery as distinctively different ones, resulting in the suspension of a service requester and the modification of its invocation procedures. In this paper, we propose a reasonable solution to realize runtime invocation of Web services, regarding structural similarities in service signatures as subsumption relations of XML scheme. Given Web services with subsumed signatures, this solution enables a service requester to invoke the Web services by translating the scheme types of the invocation parameters.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314734">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[The growth of the Internet has been accompanied by the growth of web services (e.g. e-commerce, e-health). This proliferation of web services and the increasing regulatory and legal requirements for personal privacy have fueled the need to protect the personal privacy of web service users. We advocate a privacy policy negotiation approach to protecting personal privacy [Bilateral E-services Negotiation Under Uncertainty, The Negotiation of Privacy Policies in Distance Education]. We provided semi-automated approaches for deriving personal privacy policies in [Semi-Automated Derivation of Personal Privacy Policies]. However, it is evident that approaches are also needed to ensure that providers of web services comply with the privacy policies of service users. In this paper, we examine privacy legislation to derive requirements for privacy policy compliance systems. We then propose an architecture for a privacy policy compliance system that satisfies the requirements and discuss the strengths and weaknesses of our proposed architecture.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314735">buy now</a><div></div><div></div>]]></description>

We developed also some implementations of our extension using different programming languages.

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=139</link>
<description><![CDATA[A key challenge in Web services security is the design of effective access control schemes that can adequately meet the unique security challenges posed by the Web services paradigm. Despite the recent advances in Web based access control approaches applicable to Web services, there remain issues that impede the development of effective access control models for Web services environment. Amongst them are the lack of context-aware models for access control, and reliance on identity or capability-based access control schemes. In this paper, we motivate the design of an access control scheme that addresses these issues, and propose an extended, trust-enhanced version of our XML-based Role Based Access Control (X-RBAC) framework that incorporates context-based access control. We outline the configuration mechanism needed to apply our model to the Web services environment, and also describe the implementation architecture for the system.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314738">buy now</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=141</link>
<description><![CDATA[Current Web service discovery methods are based on centralized approaches where Web services are identified based on service functionality. Examples of service functionality include car rental, hotel booking and book selling. Since higher level Web services are increasingly composed in terms of lower level Web services, it is important that service discovery not only be based on service functionality but also be based on process behavior, i.e., how a service functionality is served. Furthermore, centralized approaches to service discovery suffer from problems such as high operational and maintenance cost, single point of failure, and scalability. Another issue that has not been considered in current Web service discovery paradigms is the issue of trust and quality of service of the service provider. We, therefore, propose a structured peer-to-peer framework for Web service discovery in which Web services are located based on both service functionality and process behavior. In addition, we integrate a scalable reputation model in this distributed peer-to-peer framework to rank Web services based on both trust and service quality.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314739">buy now</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=142</link>
<description><![CDATA[The selection of web services is typically based on both functional and non-functional attributes of the service, such as the Quality of Service (QoS) levels. Reputation, a widely acknowledged non-functional QoS attribute is currently expressed as the average of user ratings given to the service. However, this expression confines reputation to the subjective perception of the end user and is limited by the lack of an objective representation of performance history. In this paper, we address the need for a reputation mechanism that couples the subjective perception of the end user with the objective view of performance history. To represent performance history, we propose a novel QoS metric termed verity. Verity measures the degree of consistency exhibited by the service provider in delivering the quality levels laid out in the service contract, over a range of previous transactions. We express reputation as a composition of user rating, the compliance levels exhibited by the provider and the verity value. We contend that this reputation expression is a more viable attribute of quality than user rating alone.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314740">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[Web Services constitute a set of technologies that many believe will change the web communication landscape within the next few years. They offer standardized and easy communications for distributed systems over the Internet. However their dynamic and distributed nature requires a well-managed system, and pending security issues prevent their widespread adoption. Meanwhile there is a big rage toward the use of Virtual Private Networks (VPNs) to secure communications in a cost-effective environment like the Internet. In this paper we explain how to merge these two technologies in a new powerful hybrid model that: (1) enables an easy management of web services, (2) provides web services security thanks to the use of dynamic and programmable VPNs, and (3) remains simple and fully integrated.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314744">buy now</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=148</link>
<description><![CDATA[This paper presents an emerging tool for security configuration of service-oriented architectures with Web Services. Security is a major concern when implementing mission-critical business transactions and such concern motivated the development of Web Services Security (WS-Security). However, the existing tools for configuring the security properties of Web Services give a technology-oriented view, and only assist in choosing the data to encrypt and selecting an encryption algorithm. The users must construct their own mental models of how the security configurations actually relate to business policies. In contrast, the tool described here gives a simplified, business-policy-oriented view. It models the messaging with customers and business partners, lists various threats, and presents best-practice security patterns against the threats. A user can select among variations on the basic patterns according to the business policies, and then apply them to the messaging model through the GUI. The result of the pattern application is described in the Web Services Security Policy Language (WS-SecurityPolicy).<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314745">buy now</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=161</link>
<description><![CDATA[We address the problem of large-scale data integration, where the data sources are unknown at design time, are from autonomous organisations, and may evolve. Experiments are described involving a demonstrator system in the field of health services data integration within the UK. Current web services technology has been used extensively and largely successfully in these distributed prototype systems. The work shows that web services provide a good infrastructure layer, but integration demands a higher level "broker" architectural layer; the paper identifies eight specific requirements for such an architecture that have emerged from the experiments, derived from an analysis of shortcomings which are collectively due to the static nature of the initial prototype. The way in which these are being met in the current version in order to achieve a more dynamic integration is described.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314747">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[Web Services are software components that can be discovered and employed at runtime using the Internet. Conflicting requirements towards the nature of these services can be identified. From a business perspective, Web Services promise to enable the formation of ad-hoc cooperation's on a global scale. From a technical perspective, a high degree of standardization and rigorous specifications are required to enable the automated integration of Web Services. A suitable technology for Web Services has to mediate these needs for flexibility and stability. In this paper, a new approach to the description of Web Service semantics is introduced. It is a visual approach based on the use of software models and graph transformations and allows for the description of innovative services while providing a precise matching concept. An implementation using current standards and tools is available. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314754">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[Much effort is being made by the IT industry towards the establishment of a Web services infrastructure and the refinement of its component technologies to enable the sharing of heterogeneous application resources. Traditional roles of the service provider, service requestor and service broker and their interactions are now being improved upon to enable more effective services. The implementation of the Web Service broker is currently limited to being an interface to the service repository for service registration, browsing and/or programmatic access. In this work, we have extended the functionality of the Web services broker to include constraint specification and processing, which enables the broker to find a good match between a service provider's capabilities and a service requestor's requirements. This paper presents the extension made to the Web Services Description Language to include constraint specifications in service descriptions and requests, the architecture of a Constraint-based Broker, the constraint matching technique, some implementation details, and preliminary evaluation results. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314741">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[UDDI registries are intended to become the world-wide lookup mechanism for web-services. As such, the registry has to provide high throughput, low response times, high availability, and access to accurate data. Replication is often used to satisfy such requirements. Various replication strategies exist, favoring different subsets of the above performance metrics. In this paper, we have a closer look at two very different replication strategies. One strategy follows the UDDI speci£cation, the second uses a middleware based replication tool. In this paper, we provide a comparison of these two approaches focusing on performance and ease of integration with an existing UDDI implementation.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314742">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[As an industry-backed registry for Web Services, UDDI plays an important role in helping requesters find suitable services. Unfortunately, the current search functions in UDDI are limited in their support for making automatic service selection decisions. While some approaches have been suggested to enhance the search capabilities in UDDI using service semantics, they suffer from limitations. These approaches either prescribe performing semantic matching outside of UDDI leaving its search function unchanged or propose embedding a specific matching engine within UDDI thereby making the search function inflexible. In this work, we present a flexible mechanism to enhance UDDI's search function. Using our approach, users can integrate multiple external matching services with a UDDI registry to support multiple external service description languages. The result is a UDDI registry with flexible and intelligent service search function that can be used for dynamic service selection. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314743">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[Pervasive Computing Environments augment physical spaces with a large number of devices and services that help users perform different kinds of tasks. Users in these environments interact with one or more web services using various devices to achieve their goals. One of the problems in these environments is discovering and coordinating different web services for achieving the user's goals. Users may not be aware of which services and devices are available in an unfamiliar environment and how to interact with them in order to achieve their goals. In order to simplify a user's interaction with the environment, we present a novel approach of modeling and managing a user's interaction with the environment based on workflows. We have built a prototype, using the popular business workflow language(BPEL) that models various processes in pervasive environments as workflows. We found that this approach improves the usability of these environments. It also increases flexibility in changing the model of interaction without having to touch individual services and applications. This approach is particularly useful in helping visitors in public spaces like malls, museums, supermarkets and hospitals. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314750">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[The potential of a large scale growth of private and semi-private registries is creating the need for an infrastructure which can support discovery and publication over a group of autonomous registries. Recent versions of UDDI have made changes to accommodate interactions between distributed registries. In this paper, we discuss METEOR-S Web service Discovery Infrastructure, which provides an ontology-based infrastructure to access a group of registries that are divided based on business domains and grouped into federations. We also discuss how Web service discovery is carried out within a federation.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314748">buy now</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=773</link>
<description><![CDATA[Extracting information extraction from the Web is a complex task with different components which can either be generic or specific to the task, going from downloading a given page, following links, querying a Web-based applications via an HTML form and the HTTP protocol, querying a Web Service via the SOAP protocol, etc. Therefore building Web Services which proceed to executing an information tasks can not be simply hard coded (ie. written and compiled once and for all in a given programming language). In order to be able to build flexible information extraction Web Services we need to be able to compose different sub tasks together. We propose a, XML-based language to describe information extraction Web Services as the compositions of existing Web Services and specific functions. The usefulness the proposed framework is demonstrated by three real world applications. (1) Search engines : we show how to describe a task which queries Google's Web Service, retrieves more information on the results by querying their respective HTTP servers, and filters them according to this information. (2) E-Commerce sites : an information extraction Web Service giving access to an existing HTML-based e-commerce online application such as Amazon is built. (3) Patent extraction : a last example shows how to describe an information extraction Web Service which allows to query a Web-based application, extract the set of result links, follow them, and extract the needed information on the result pages. In all three applications the generated description can be easily modified and/or completed to further respond the user's needs and create value-added Web Services.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314749">buy now</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=306</link>
<description><![CDATA[We present a technique called Dynamic Distributed Service Coordination Protocol (DDSCP) that enables dynamic and distributed coordination for composed services and applications in telecommunication networks. Individual service components are modeled as web services and DDSCP facilitates coordination among these components by dispatching executable processes to the service components that specify different steps that the service component must follow in response to (receipt of) specific messages and events. The collective and concurrent execution of these processes at different service components achieves overall goals of the service. The planning and creation of these processes is not our focus in this paper. We describe the structure and processing of different messages DDSCP, and describe how this protocol can work. Our model has several advantages over the existing service platforms for 3rd Generation Mobile Networks, such as Parlay/OSA, and the web-service composition models. These advantages include introduction of flexibility among network components at finest level, ease of creation of highly customized services, easy integration with foreign components, reduced application complexity, increased reuse of application components, and possibility of increased user participation in managing her services, and thus reducing load on the network.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314751">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[Web services advocate loosely coupled systems, although current loosely coupled applications are limited to stateless services. The reason for this limitation is the lack of a method supporting matchmaking of state dependent services exemplarily specified in BPEL. In particular, the sender's requirement that the receiver must support all possible messages sent at a certain state are not captured by models currently used for service discovery. Annotated deterministic finite state automata provide this expressiveness. In this paper the transformation of a local process specification given in BPEL to annotated deterministic finite state automata is presented.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314753">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[Web Services technology for interoperability, dynamic discovery and integration of distributed components is to be applied in various environments, such as networks of relatively narrow and unstable wireless connections. However, in such environments it is necessary to deal with resource limitation. Our work adopts mobile agent technology in response to this problem and presents a mobile agent framework for Web Services integration. This framework utilizes BPEL (Business Process Execution Language for Web Services) for description of the integration logic, and provides declarative descriptions for physical behaviors (migration and cloning). This facilitates addition or change of physical behaviors according to the environmental conditions while preserving the integration logic. This paper especially focuses on formal definition and discussion of our framework.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314756">buy now</a><div></div><div></div>]]></description>

Reliable messaging is one of the key issues addressed for quality of services in Web services. In this paper, we propose a reliable message scheme designed for mobile environments in the context of a Web services architecture; Web services -Wireless Reliable Messaging (WS-WRM). We also consider the federation issues with emerging specifications proposed by leading Web services standard groups. We eventually intend to extend the reliability to mobile end-nodes in a more efficient way.

<description><![CDATA[New sensor technologies, powerful mobile devices, and wireless communication standards strongly proliferate ubiquitous and pervasive computing. This is particularly true for healthcare applications. Modern non-invasive unobtrusive sensors enable sophisticated monitoring of the human body. As a result of this monitoring a growing amount of elderly people suffering from chronic diseases will benefit from an enhanced quality of life and improved treatment. Healthcare applications process a vast amount of continuously generated data, this has become a serious challenge. Data stream management addresses this problem in general. However, healthcare applications have additional requirements, e.g., flexibility and reliability. As a consequence, we propose the combination of a sophisticated information infrastructure, called hyperdatabase, and data stream management. Hyperdatabases already allow for reliable process management in a peer-to-peer fashion. In this paper, we elaborate the close relation between distributed process management and data stream management. Further, we show that data stream processing can significantly benefit from an infrastructure for reliable process management. We present the architecture of our prototype infrastructure that supports processing of continuous data streams with a high degree of flexibility and reliability.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314758">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[The Web is moving toward a collection of interoperating Web services. Achieving this interoperability requires dynamic discovery of Web services on the basis of their capabilities. The capability of a service can be properly determined by using not only its functional description (or service interface), but also its quality attributes as judged by previous users of the service. We develop a service repository that extends UDDI registries. This repository combines an ontology of attributes with evaluation data. We base our repository on a new query and manipulation language based on DAML. Our language includes support for a rich set of operations, which are needed to maintain an attribute ontology, publish services, rate services, and select services based on their functional attributes as well as evaluations by others. We have implemented our approach and evaluated its practical completeness via a number of key query and manipulation templates. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314759">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[Recently, Web services have become a new technology trend for Enterprise Application Integration (EAI) and more and more applications based on Web services are emerging. One of the problems in using Web services in business applications such as logistics is services composition automatically and efficiently. In this paper, we present a Dynamic, Demand-Driven Web services Engine called D3D-Serv to implement composite service functionality that is used to dynamically build composite services from existing services according to different business logics and requirements. In this D3D_Serv framework, the most challenging function to implement is dynamic selection of service providers at run time. The highly dynamic and distributed nature of Web services often makes some service providers overloaded at certain times while others idle. To solve this problem, we propose an efficient services selection and execution strategy that is based on the queuing theory and can provide guarantees for the QOS (Quality of Service) under provider's limited resources. Preliminary experimental results have shown that this algorithm is effective. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314760">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[The vision of the Semantic Web is to reduce manual discovery and usage of Web resources (documents and services) and to allow software agents to automatically identify these Web resources, integrate them and execute them for achieving the intended goals of the user. Such a composed Web service may be represented as a workflow, called service flow. Current studies of Web services are not sufficient for automatic composition. This paper presents different types of compositional knowledge required for Web service discovery and composition: syntactic, semantic and pragmatic knowledge. As a proof of concept, we have implemented our framework in a cardiovascular domain which requires advanced service discovery and composition across heterogeneous platforms of multiple organizations. Within this framework, we describe (1) How to represent the compositional knowledge, which plays a role in service discovery and composition, in DAML-S; (2) How heterogeneous medical services interoperate in a composed medical service flow. (3) To solve this knowledge level integration, we build on an ontology integration method called SEMIO (Semantic Interoperability).<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314762">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[The dynamic nature of the Grid environment brings challenges to the services provisioning technique. A major aspect of Grid is to match demands for services with resources. Since resources and demands are fluctuating, Grid services provisioning need to be adjusted accordingly in responding to changes. In this paper, we propose a novel approach, Grid services migration, to enabling services provisioning on demand. The major motivation is to achieve the desired Quality of Service (QoS) such as performance, reliability, and etc. of Grid services on resources assembled dynamically responding to dynamic demand. In this paper, the technical characteristics of Grid services migration and its taxonomy are introduced. The Grid service migration algorithms are also presented. The Grid services migration framework with MAPE (Monitor, Analyze, Plan, and Execute) loop is proposed based on Open Grid Services Architecture (OGSA) and the prototype named Services Ecosystem, a resilient infrastructure for services provisioning on demand in Grid is developed. Demonstrations and experiments are conducted and results are presented to illustrate the capabilities of Grid services migration.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314763">buy now</a><div></div><div></div>]]></description>

Web services play a key role in the architecture of GRIA, chiefly through their interoperability and security features - they provide a well-defined means of limiting clients' access to discrete operations, thus allowing clients to do "work" on a remote application server without giving them full shell access to the server. In this paper, we focus on requirements, business processes and security, and interoperability and standardisation issues raised by this work. We also describe some of the lessons learned through experience of designing, implementing and deploying a prototype system, GRIA v1. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314764">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[Whilst the vision of a robust Service-Oriented Architecture (SOA) is very seductive it engenders many technical challenges. The main challenge is the development and support of runtime cross-standard service activation and interoperation. Such interoperation will provide a vital stepping-stone towards the integration of the emerging SOA standards and legacy services - those developed using existing middleware architectures such as DCOM, COBRA, J2EE, Web service, JXTA, and Jini. Much related works already exist including WSIF framework, which provides APIs to support design-time invocation of cross-standard Web services deployed on multiple SOAP packages. However, this paper focuses on a runtime self-regenerative mechanism related to adaptive service invocation code. The paper will present a runtime service adaptation mechanism, which supports end-users to dynamically adapt to variations in the execution environment, without altering their original design, crossing multiple standards (both synchronous and asynchronous invocation models) and middleware architectures. This paper also introduces a proposed "Polyarchical Middleware" architecture to support such self-regenerative service adaptation. An illustrative example will be used to describe the approach and the current implementation. The paper will conclude with general remarks and mention of further work.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314765">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[The emerging paradigm of web services opens a new way of web application design and development to quickly develop and deploy web applications by integrating independently published web services components to conduct new business transactions. As research aiming at facilitating web services integration and verification, WS-Net is an executable architectural description language incorporating the semantics of Colored Petri-net with the style and understandability of object-oriented concepts. WS-Net describes each web services component in three layers: interface net declares the services that the component provides to other components; interconnection net specifies the services that the component acquires to accomplish its mission; and interoperation net describes the internal operational behaviors of the component. As an architectural model that formalizes the architectural topology and behaviors of each web services component as well as the entire system, WS-Net facilitates the verification and monitoring of web services integration.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314766">buy now</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=779</link>
<description><![CDATA[In this paper, we propose the concepts of virtual partner and inspector into the web services composition. Virtual partner, as an IT level concept, is a web service (pseudo web service) using the same interface with the actual partner but different binding message. A virtual partner can be invoked directly by a business process described by BPEL, so that the BPEL programmer can test both application's functionality and non functionality performance early in the development cycle to avoid any problems in the final runtime, or test the selection of their partners in business level design. The IT virtual partners provide developers with a range of the techniques which let them explore every aspect of their program. Inspector is proposed when using the third -party process engine. An inspector itself is also a web service. The programmer can register any required output information in it. The IT virtual partner and the inspector concepts have been integrated in our WSCE, a flexible Web Services Composition Environment for a business process. WSCE is a prototype of autonomic modeling and simulation environment. With the help of a third-party BPEL engine, it provides programmer with concepts and tools to facilitate business process programming. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314767">buy now</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=317</link>
<description><![CDATA[This paper introduces a method for automatic composition of Semantic Web services using Linear Logic (LL) theorem proving. The method uses Semantic Web service language (DAML-S) for external presentation of Web services, while, internally, the services are presented by extralogical axioms and proofs in LL. We use a process calculus to present the composite service formally. The process calculus is attached to the LL inference rules in the style of type theory. Thus the process model for a composite service can be generated directly from the proof. The subtyping rules that are used for semantic reasoning are presented with LL inference figures. We propose a system architecture where the DAML-S translator, the LL theorem prover and the semantic reasoner can operate together to fulfill the task. This architecture has been implemented in Java.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314769">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[The semantic Web technology and the Web services description language extensibility may be combined to describe services in an unambiguous and machine interpretable way, automating Web services discovery, selection and invocation. In this paper, we present an algorithm and a prototype for the automatic composition of Web services that implement workflows described in a high level language. Our approach has many advantages comparing to the manual creation of a simple program composition, such as smaller implementation time and cost, reliability with the generation of contingency plans, greater capacity to evolve with the dynamic service discovery, and faster execution time with the use of heuristics. We use the OWL-S ontology to semantically describe Web services metadata and indexes to help selecting them. The proposed algorithm considers that equivalent services may have different interfaces and also respects preferences of the users. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314770">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[Web services are rapidly becoming popular as a vehicle for the design, integration, composition, and deployment of distributed and heterogeneous software. However, while industry standards for the description, composition, and orchestration of Web services have been under discussion (and development) for quite some time already, their conceptual underpinnings are still in their infancy. Indeed, conceptual models for service specification are rare so far, as are investigations based on them. This paper presents a multi-level service composition model that perceives service specification as going through several levels of abstraction, from transactional operations to the end user. Importantly, the model allows for specification of desirable composition properties at all levels. Different ways of achieving these properties as well as implications of the model are addressed.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314771">buy now</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=320</link>
<description><![CDATA[Web Services are emerging technologies that enable application-to-application communication and reuse of autonomous services over the Web. Recent efforts, OWL-S, model the semantics of Web Services that includes the capabilities of the service, the service interaction protocol, and the actual messages for service exchanges. However, there is a need to automate discovery, selection and execution of OWL-S services. Further, a framework that meets the quality of service (QoS) requirements for ad hoc Internet based services is rarely provided. In this paper, we have proposed a rule-based framework, called SemWebQ, which manages workflows composed of Semantic Web Services. SemWebQ is capable of conducting QoS-based adaptive selection as well as dynamic binding and execution of Web Services according to the semantics of workflow, thereby rendering a resilient and adaptive Web based service flow. A series of experiments performed on the SemWebQ with real Web Services have confirmed the effectiveness of proposed framework with respect to adaptive selection and execution of the Web Services in Web based workflows.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314773">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[As more and more Web services are deployed, Web service's discovery mechanisms become essential. Similar services can have quite different QoS levels. For service selection and management purpose, it is necessary to explicitly, precisely, and unambiguously specify various constraints and QoS metrics for Web services descriptions. This paper provides a novel DAML-QoS ontology as a complement for DAML-S ontology to provide a better QoS metrics model. Three layers are defined together with clear role descriptions for developments. Cardinality constraints are utilized to describe the QoS property constraints. Basic profile is presented for general web service's description and the speed startup of ontology definition. Matchmaking algorithm for QoS property constraints is presented and different matching degrees are described. When incorporated with DAML-S, multiple service levels can be described through attaching multiple QoS profiles to one service profile. Well-defined Metrics can be further utilized by measurement organizations to guarantee the promised service level. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314772">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[Reflection is a powerful tool for the adaptation of applications at runtime. The modification of Web services is a task that entails the modification and compilation of the source code, as well as the deployment of the new version of the Web service in the application server. In this paper, we introduce RAWS (Reflective and Adaptable Web Service), a Web service design model based on a reflective architecture of two levels. RAWS allows both the dynamic modification of the definition and implementation structure of the Web service, and the dynamic modification of the Web service behavior in order to change the existing code or to add new functionalities. All these dynamic modifications are performed directly on the code during execution, with no need to have the Web service source code. RAWS improves Web services adaptability and maintainability, as well as the ability for authorized clients to remotely modify them.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314774">buy now</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=322</link>
<description><![CDATA[Developers write Web service composition programs in terms of functionalities (e.g., "WebSearch") to postpone choosing which services of the same functionality to invoke (Google or Yahoo). We provide a higher level of abstraction than this for higher reuse. We express high-level "patterns" (e.g., "SearchAndCollectData") as both objects that can be "specialized" to particular applications ("SearchAnd-DownloadPapers" vs. "SearchAndAddBooksInCart") and objects that are reusable in the construction of higher-level ones. Our approach lets developers write patterns in terms of high-level functionalities (e.g., "CollectData") and later decide on services to compose that have lower-level functionalities (e.g., "DownloadPapers" or "addBooksIn-Carts"). We describe our prototype and show an example of nested pattern specialization. We also discuss a reuse trade-off, showing that too much abstraction makes the pattern less expressive. Rather, we suggest developers capture what must be guaranteed in every context of invocation, regardless of the service selection.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314775">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[Service matchmaking and composition has recently drawn increasing attention in the research community. Most existing algorithms construct chains of services based on exact matches of input/output types. However, this does not work when the available services only cover a part of the range of the input type. We present an algorithm that also allows partial matches and composes them using switches that decide on the required service at runtime based on the actual data type. We report experiments on randomly generated composition problems that show that using partial matches can decrease the failure rate of the integration algorithm using only complete matches by up to 7 times with no increase in the number of directory accesses required. This shows that composition with partial matches is an essential and useful element of web service composition.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314776">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[Service composition refers to the aggregation of services to build complex applications to achieve client requirements. It is an important challenge to make it possible for users to construct complex workflows transparently and thereby insulating them from the complexity of interacting with numerous heterogeneous services. We present an extension to the Triana PSE to facilitate graphical Web service discovery, composition and invocation. Our framework has several novel features which distinguish it from other work in this area. First, users can graphically create complex service compositions. Second, Triana allows the user to share the composite service as a BPEL4WS graph or expose it as a service in a one-click manner. Third, Triana allows the user to easily carry out "what-if" analysis by altering existing workflows. Fourth, Triana allows the user to record provenance data for a workflow. Finally, our framework allows the user to execute the composed graph on a Grid or P2P network. Triana is a part of the GridLab and GridOneD projects and is used in the GEO 600 project.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314777">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[We are developing an Interoperable Distributed Simulation (IDSim) framework that builds upon the Open Grid Services Infrastructure (OGSI) to provide distributed simulation services to federated simulators. OGSI and web technology standards provide novel opportunities for a domain-independent, distributed simulation framework to support extensibility by users of the system. IDSim services can be extended through inheritance to add or extend operations tailored to the needs of specific simulation domains. XML-based documentation of simulation models allows the framework to operate upon the contents of shared events (e.g., content-based distribution). Additionally, exposure of the underlying framework through Grid Web Services Description Language (GWSDL) allows for tool-based extensibility; that is, tools can be developed to create and manage complex federations. This paper presents the design and architecture of IDSim with a focus on extensibility; other design concepts are presented where relevant.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314779">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[Grid computing provides the basic software infrastructure for integrating geographically distributed resources and services through standardized Grid services. One of the key challenges to enable the broader use of Grid services beyond the domain of scientific computing is the ability to perform complex tasks that require the modeling and coordination of the enactment of a number of distributed Grid services. Workflow technology is a good candidate for supporting Grid service flow. However, traditional workflow is static, thus unable to exploit the dynamic information available in the Grid and respond to the dynamic nature of the Grid. In this paper, we present an adaptive framework that provides adaptive management of Grid service flows. The framework is based on an Adaptive Grid Service Flow Model and is supported by an Event-Trigger-Rule (ETR) technology that will be used to trigger rules in a distributed fashion to adapt a Grid service flow to the dynamic Grid environment and the changing requirements of a Grid application.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314782">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[The information service is a key component of a Grid environment and critical to the operation of a computational Grid. In this work, an OGSA (Open Grid Services Architecture) based Information Service that complies with OGSI (Open Grid Services Infrastructure) is presented. The main functionality of this Information Service is the provision of information essential for applications running on a computational Grid such as resource information, job status, resource workload, service meta-information, and queue status. This OGSI-compliant Information Service is built on Globus Toolkit MDS-3, and it works with meta-scheduling services and local job scheduling systems to support resource discovery, job scheduling, and execution management. In this paper, the architecture of the Information Service and the models of information data organization are presented. Some implementation issues are discussed as well. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314783">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[The advent of Web services has made automated workflow composition relevant to web based applications. One technique, that has received some attention, for automatically composing workflows is AI-based classical planning. However, classical planning suffers from the paradox of first assuming deterministic behavior of Web services, then requiring the additional overhead of execution monitoring to recover from unexpected behavior of services. To address these concerns, we propose using Markov decision processes (MDPs), to model workflow composition. Our method models both, the inherent stochastic nature of Web services, and the dynamic nature of the environment. The resulting workflows are robust to non-deterministic behaviors of Web services and adaptive to a changing environment. Using an example scenario, we demonstrate our method and provide empirical results in its support.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314784">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[Architectural mismatch [Architectural Mismatch, or, Why it's hard to build systems out of existing parts]; the semantic and syntactic gap preventing component composition, can be partially alleviated through the ubiquity of the protocols for service composition (syntax). And yet, the semantics of service or component composition have remained elusive. The contribution of this paper builds on the notions introduced by grammar-oriented object design (GOOD) using the notion of manners to specify the semantics of services and drive their automated composition through dynamically re-configure architectures enabled through GOOD. This leads to the use of manners for explicit service semantics representation in a re-configurable architectural style. We describe the base requirements for automated component and services composition and show how automated assembly of components and services can be accomplished through a dynamically reconfigurable (DyRec) architectural style. In addition, we show how this vision of dynamic reconfiguration is naturally supported by the Web services framework, because it derives from some of the core requirements of the Service Oriented Architectures (SOA) style embodied by Web services. Further, we discuss how such a DyRec architectural style can be implemented using grammar-oriented object design (GOOD) and describe a project that led to a tool called the Business Compiler, to accomplish dynamic composition and collaboration. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314785">buy now</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=332</link>
<description><![CDATA[The emergence of Web services has led to more interest into Web service composition, which is an active area of research. The formidable problem of efficient and effective composition of existing Web services is the subject of much current attention. The study of workflow model is one of the most important parts and a key layer of Web service composition. The existing approaches have difficulties in modeling dynamic and complex service composition process, so we propose a novel workflow model named Service/Resource Net (SRN) for Web service composition, which is an extended Petri-net-based model with some new elements, such as time, resource taxonomy, condition, etc. To establish formal concept system of Web service taxonomy in SRN, we present Web service semigroup based on group theory. Moreover, meta-service is proposed based on the definition of generating element in cyclic monoid. As the supplement of traditional analysis methods of basic Petri net, some new methods based on graph theory are presented for SRN analyzing and evaluating. For system and methodology validation purpose, SRN is applied to a case study in our research project.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314786">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[Network Centric Information Infrastructure (NCII) is a toolkit of prefabricated software components together with a composition framework for integration and experimentation. Typical distributed system applications of a toolkit such as NCII can be applied to air traffic management, shop floor control and in-flight connection to Internet. The composition framework has gone though through three generations of changes in the past five years and it is a good illustration of a paradigm shift from Object-Oriented Architecture, through Component-Based Architecture to Service-Based Architecture.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314787">buy now</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=335</link>
<description><![CDATA[This paper gives a first insight in an ongoing investigation. Our generic aim is to describe the current situation of available Web Services in context with their quality of service (short QoS) behavior. The current quality behavior of offered Web Services should be evaluated in particular as an important aspect of an effective Service Level Management. After providing an introduction to Web Service technology, this contribution primarily aims to describe the topic of service level agreements (short SLA) management in such environments. In this context, we will highlight the general contents of SLA agreements, describe the interaction chain for service provision that arises in Web-service-based solutions, and provide a brief explanation of the opportunities offered by the WSLA framework that IBM has developed especially for Web Services. Finally we describe the conception, prototypical development and the possible application of a measurement service for monitoring the quality behavior of an specific Web Service. This measurement service can be used to support service level agreements.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314788">buy now</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=782</link>
<description><![CDATA[Web services are rapidly becoming the technology of choice for integrating distributed application components in heterogeneous computing environments. In this paper, we present a novel e-commerce prototype application that itself would not be feasible without the leverage provided by underlying Web services technologies for flexible design and rapid prototyping. The application is a Model-driven Service Brokerage that allows service providers to model, advertise, validate, and create a wide range of services (e.g. Internet access services such as DSL, and Cable, Video-on-demand, etc) in an open marketplace in an automated fashion. The application answers real needs expressed by today's large Service Providers and goes beyond the current state-of-the-art in online communication marketplaces. It consists of several functional components - i.e. a service dependency modeling tool, brokerage engine, location services, and workflow engine - that have been independently developed on diverse platforms, e.g., J2EE, .NET. To efficiently integrate these components, we have designed a distributed Web services architecture, in which one Web Service functions as a "hub" between previously disconnected components, another works as a "wrapper" of legacy data systems, while another "orchestrates" invocations of these services. Use of Web services has enabled parallel and independent development and testing, greatly increasing productivity and reducing time to get the system operational. It has also fostered the development of new Brokerage features, which would have been difficult to plan without first experimenting with a "live" system. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314790">buy now</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=338</link>
<description><![CDATA[Business-to-Business will be a considerable market in the near future of Internet e-business. In this future market, several providers need to be able to integrate or exchange information in providing a global service. The problem that we want to tackle in this paper is related to the existing information sources in the current Internet environment. That is how to integrate existing Web sites each other to become a new Internet service ? The difficulty comes from a historical objective. Internet Web sites were developed for human users browsing and so, they do not support machine-understandable as well as inter-provider interaction. To overcome this gap, we need a framework to systematically migrate the existing presentation-oriented Web sites to service-oriented one. Evidently, redeveloping all of them is an unacceptable solution. In this paper, we propose a mechanism of Web Service gateway in which existing Web sites are wrapped by several Web Service wrappers. Thus, without any efforts to duplicate the Web sites code, these services inherit all features from the sites while can be enriched with other Web Service features like UDDI publishing, semantic describing, etc... As a consequence, they can be easily integrated each-other in a Business-to-Business schema to provide a more valuable service for users. This Web Service gateway was developed in Toshiba with Web Service Generator, allowing automatically generate Web Service wrappers. By using this system, several "real" Web services were generated and made available for use. The Web Service gateway and these services are also presented and evaluated in this paper.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314793">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[For Web Services to fulfill their promise in truly heterogeneous environments, the different base operations being included in Web Services will need to appear in multiple Web Services with different names as well as different authorization and authentication mechanisms, different Service Level Agreements, and even different formats. We describe Service Views and rule groups which together provide an adaptation layer at which these changes can be described and enforced. Service Views include the ability to offer different views on WS components by altering the WSDL[Web Services Description Language] contract. Rule groups provide information directing these changes, as well as other policies to be automatically enforced underneath the services.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314794">buy now</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=340</link>
<description><![CDATA[Recent technologies including web services, business process modeling tools, and grid computing, are key to facilitating business agility. Web services standardize application interfaces to ease inter-application communication, and facilitate standards based business process management. Grid computing provides a way for virtualizing heterogeneous resources to collectively yield a computationally powerful IT environment with tremendous promise in improving utilization levels of individual IT resources. By leveraging web services, a standards based grid is being envisaged in the OGSA model. In this paper, we explore the complementarities of web services and business process management (BPM) technologies. We also lay the foundation for using web services based BPM in solving orchestration and workflow issues in grid computing.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314796">buy now</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=341</link>
<description><![CDATA[We have developed an application service hosting middleware for enterprise information systems, "Polimatica", upon which a policy-customizable private virtual organization (pVO) is built. The pVO is a collection of customizable application services in the global grid computing environment. "Polimatica" is distinctive in terms of abstraction capabilities in (1) policy instance description, (2) view synthesis of an extensive resource data model, (3) operation aggregation on the OGSI extension interfaces. The performance to enforce the policy instances is measured in a laboratory testbed for an enterprise ASP, providing B2B e-commerce (BizEngine/WS) and interactive media communication service (LiveComm). We have verified that, in 60 seconds, the feedback loop in a pVO adjusts the application services as customized given the changing environment.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314797">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[The number of networked multimedia platforms that are introduced into the market has increased dramatically in recent years. Current approaches to multimedia distribution do not scale to this growing set of client configurations and heterogeneous dynamic networks. We propose a distributed architecture that offers a scalable solution to multimedia publication and distribution in such heterogeneous environments. It builds upon recent standardization efforts related to web services. This paper details the multimedia web services at the proxy server, that cooperate on a loosely coupled basis to tailor content creators' multimedia presentations to clients' environments. The experiments show that our web service-oriented architecture offers a significant added value in heterogeneous multimedia environments. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314799">buy now</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=342</link>
<description><![CDATA[We present an approach for converged communication services over IP, based on the concept of WSIP (Web Service SIP). In our approach, each WSIP node is both a SIP endpoint that communicates in the SIP world through SIP signaling, and a web service SOAP node that provides a native and generic service integration environment for binding SIP based communication in web services. The unification of SIP with web service provides a new converged communication paradigm. It allows dynamic service discovery and binding that integrate SIP as a component in the business transaction. The clear separation of service integration environment and SIP signaling in our approach maintains the simplicity and efficiency of the existing SIP protocol, while leverages the power of both methods in IP based communication services. The ubiquitous service integration nature of web service provides a disciplined solution to maintain and update large number of SIP endpoints from different installation bases. It enables dynamic monitoring, repairing, and updating SIP UA endpoints, which is essential to the success of VoIP using SIP. The proposed approach was implemented in a prototype research system, and several advantages of WSIP over the existing approaches are observed. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314800">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[Information visualization has been acknowledged as an important tool in software decision support. But usually visualizations are static and just used for presentation rather than exploration. Interactive statistical data visualization can be used as a powerful tool which reaches beyond the limits of static graphs. We developed Code Mapping, a software platform for visualization and manipulation of complex and large software portfolios. Code Mapping builds data-rich, graphical representations that are color-coded for function, call position and experimental interaction data. The functions implemented in Code Mapping allow collaboration and organization of software architecture diagrams in a visual model format; this feature is specially useful for web services development and other Internet application code. The aim of this paper is to describe a tool which helps to visualize the software development and to present a new way to visualize software in a three-dimensional CAVE?o? environment. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314802">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[In this paper we describe JClarens; a Java based implementation of the Clarens remote data server. JClarens provides web services for an interactive analysis environment to dynamically access and analyze the tremendous amount of data scattered across various locations. Additionally this research is aimed to develop a service oriented Grid Enabled Portal (GEP) that provides interface and access to several Grid services to give a homogeneous and optimized view of the distributed and heterogeneous environment. Other than showing platform independent behavior provided by Java, the use of XML-RPC based Web Services enabled JClarens to be a language neutral server and demonstrated interoperability with its Python variant. Extreme care has been taken in the usage and manipulation of various Java libraries to cater the needs of high performance computing. The overall exercise has yielded in a prototype with strong emphasis on security and virtual organization management (VOM). This shall provide a common platform to support development of larger, more flexible framework with future aims to integrate it with a loosely coupled, decentralized, and autonomous framework for Grid enabled Analysis Environment (GAE).<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314803">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[J2EE components and APIs have remained largely unmined, and their potential as performance barometers therefore largely unrealized, because the tools businesses have traditionally wielded to service transactions-database servers, directory services, application servers themselves-have been unable to provide businesses and software developers the access they need to capture, measure, and optimize discrete transactions. Businesses that lack insight into J2EE components and APIs lack the ability to manage some of e-business's most vital performance assets, assets that, when performing poorly or not at all, can down whole distributed applications. This paper discusses the requirements of J2EE application performance management systems and five commercial tools. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314804">buy now</a><div></div><div></div>]]></description>

In order to address efficient integration of conversational Web services, we create a unified specification model for both conversation protocol and composition; we propose methods to integrate a partner service with complex conversation protocol into a composition of Web services; assure the correctness of composition by formal verification. The mapping between our model and BPEL4WS is also discussed.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314810">buy now</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=787</link>
<description><![CDATA[Over the past decade, classic client side applications with Model-View-Controller (MVC) architecture haven't changed much but become more complex. In this paper, we present an approach of building desktop applications with Web Services in an explicit message-based MVC aradigm. By integrating with our publish/subscribe messaging middleware, it makes SVG browser (a Microsoft PowrrPoint like client application) with Web Service style interfaces universally accessible from different client platforms - Windows, Linux, MacOS, PalmOS and other customized ones. Performance data suggests that this scheme of building application around messages is a practical architecture for the next generation Web application client. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314812">buy?  now</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=353</link>
<description><![CDATA[In this paper, we present an approach to enable access control for semantic web services. Our approach builds on the idea of autonomous granting of access rights, decision making based on independent trust structures and respects privacy requirements of the users. Our framework allows the specification and computation of complex access control policies in a manageable and efficient way. Therefore, our approach is useful not only in web services based applications (typically client-server architecture)but also in peer to peer and agent based applications.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314813">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[In this paper, we introduce the authorization issues for Web Services. We introduce the authorization service provided by Microsoft?o? .NET MyServices and then briefly describe our proposed modifications and extensions to the authorization service. We discuss the application of the extended authorization model to a healthcare system built using Web Services. We used the XML Access Control Language (XACL) to specify policies in XML and control access to the patient records stored in XML format. We then evaluated the suitability of XACL as an authorization policy language for Web Services. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314814">buy now</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=355</link>
<description><![CDATA[The execution time of computationally-intensive applications such as protein folding and fractal generation can be reduced by implementing these applications as web services that run in parallel. Additionally, some of these web services may save state periodically to resume execution later on. However, currently, there is no solution to load balance this class of web services, and to replicate the saved state for the purposes of resumption. This paper describes the architecture of JULIET, a system that load balances .NET web services across a Windows cluster in a distributed fashion. The system is also fault tolerant since it supports failovers and replication of data generated by the web services at the application level. The system is designed to be minimally-visible to the web service and the client that consumes it. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314815">buy now</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=788</link>
<description><![CDATA[Currently web services composition problems are addressed using AI planning techniques. The team-based approach, with emphases on the sharing of mental models and proactive collaboration, provides an alternative to current static approaches to web service composition. The approach provides clear advantages for proactive handling of failures that may be encountered during execution of a complex web service. The paper proposes a generic framework for dynamic web-service composition, and extends the CAST architecture to realize the framework. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314820">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[Web Services (WS) technology is becoming pervasive in the development of distributed systems and is an appealing vehicle for service presentation and horizontal integration. On the other hand, Model Integrated Computing (MIC) offers a means of system integration in the vertical direction by using domain-specific modeling, and then synthesizing the software system from the high-level model using a model-specific generator. This paper presents a meta-modeling approach to WS to explore the application of MIC in WS development and its contribution.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314824">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[This paper investigates the issues when several complementary geospatial web services are chained to be a customized application process. This paper proposes a conceptual framework and a data structure, called Service Chain Graph (SCG), to describe the geospatial web service integration and the dynamic construction of service chaining process. A set of dynamic structural transformation rules is given to model the dynamic process of service chaining. Implementation issues are discussed and a prototype system is briefly presented for integration of several distributed, heterogeneous geospatial data services based on the model proposed by this paper.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314826">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[Today, web services are pervasive and omnipresent in the Internet and within enterprises. Even though there are massive web services specifications development underway, early adoption by developers and tool vendors is becoming a need. The potential growth of this technology is highly predictable because of its universal acceptance and use among the developer community. This industry may expect to grow enormously based on the support from various communities that benefit from this technology. Researches are carried out in various standards bodies on various aspects of web services such as definition, architecture, security, discovery, interoperability, etc. As we are committed to the success of this technology, we need to research on service oriented containers that makes web services potential more constructive. This paper proposes a container for web services which can manage and monitor the state and behavior of web services, which may address the Quality of Service (QoS) factor for web services. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2004/2167/00/2167toc.xml&amp;DOI=10.1109/ICWS.2004.1314828">buy now</a><div></div><div></div>]]></description>

<description><![CDATA[Composite service evolution is one of the most impor-tant challenges to deal with in the field of service compo-sition. In particular, this paper presents, LiveMig, an approach to live migration of composite service instance, which is a critical step for online composite service evo-lution. In LiveMig, a set of change operations preserving soundness is first defined. Second, a live instance state migration algorithm is proposed to determine if the state migration is allowed or not, and to compute the exact state after the migration. Finally, the correctness of Li-veMig is theoretically proved, and an extensive set of simulations are performed to show its feasibility and ef-fectiveness <div align="center"><a href="uploadfiles/2009/VIDEO/ICWS2009-0085/ICWS2009-0085.html" target="_blank"><strong>&amp;gt;&amp;gt;&amp;gt; View Video(Flash Player 9 please.
