Evolving Web Service Applications Using UML and OWL-S

Web service provides a way to satisfy time-to-market and quality need by reusing services and building applications. Dynamic evolution offers flexibility so that software can adapt to unforeseen and fluctuating business requirements. OWL-S, based on OWL, is a service ontology language. The semantics provided by OWL-S support automation of service discovery, invocation, and service composition. In this paper we propose a framework to support dynamic evolution of Web applications based on semantic web service. This framework proposes a method to consider Web service features and to derive service description from use- case model. A prototype is implemented to show the validity of this framework.
