Dynamically Managing the Delivery of Web Services via Workflow and Feedback

The concept of automating the delivery of Web services functionality is an active research topic. This paper presents a comprehensive and overarching framework that supports the execution and delivery of Semantic Web services within the context of workflow management, and addresses the issues related to Virtual Organizations. The goal is to add semantics to Web services to endow them with capabilities currently lacking in the literature, but necessary for their successful deployment in future systems. In this paper, we indicate how our Knowledge-based Dynamic Semantic Web Services (KDSWS) Framework addresses the activities involved in managing and monitoring Semantic Web Services by using both a meta-model and meta-process approach. In particular, the following issues are addressed: 1) semantic specification of services capabilities including quality of service, trust, and security; 2) the execution and delivery of services 3) workflow management; and 4) resource management, interoperation and evolution of the Virtual Organization.
