Runtime Service Discovery and Reconfiguration Using OWL-S Based Semantic Web Service

In recent business environment where collaboration between organizations is essential, business organization must fast adapt to changing user and market demands. SOC (service-oriented computing) is believed to be a prominent paradigm for efficient businesses application development. Semantic web enables users to locate, select, employ, compose, and monitor Web-based services automatically. OWL-S, ontology of service, helps this location, selection, and composition of services. In this paper we propose a framework, to support dynamic reconfiguration of service-oriented applications. This framework supports semantic discovery, ranking, and dynamic reconfiguration of services using OWL-S based ontology. A prototype is provided to show the validity of this framework.
