A New Framework for Web Service Discovery Based on Behavior

With the rapid expanse of the web service over the internet, discovering related web service is becoming the most urgent problem. Traditional methods focus on the interfaces of service through using ontology without considering service behavior. In this paper, the Calculus of Communicating Systems(CCS) is exploited to specify web service´s behavior, weak equivalence on behavior is used for matchmaking between the advertised service and the requested service. Then, The paper combines behavior matching with fuzzy similarity of ontological concept to propose a new matching algorithm for web service. Therefore, a promising framework for web service discovery is proposed.
