Provisioning Resilient, Adaptive Web Services-based Workflow: A Semantic Modeling Approach

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 effec...
