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.","PeriodicalId":135986,"journal":{"name":"Proceedings.

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 multichannel 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 multichannel integration and related retail processes. We propose a reference service oriented architecture for usage of Web services involving inter and intra company systems for multichannel integration.","PeriodicalId":135986,"journal":{"name":"Proceedings.

Recent efforts, OWLS, 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 SetnWebQ, 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.","PeriodicalId":135986,"journal":{"name":"Proceedings.

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.","PeriodicalId":135986,"journal":{"name":"Proceedings.
