Pathak, Jyotishman, Koul, Neeraj, Caragea, Doina and Honavar, Vasant (2005) Discovering Web Services over the Semantic Web. In Proceedings 7th ACM International Workshop on Web Information and Data Management, Bremen, Germany.
This paper describes a framework for ontology-based flexible discovery of Semantic Web services. The proposed approach relies on user-supplied, context-specific mappings from an user ontology to relevant domain ontologies used to specify
Web services. We show how a user's query for a Web service that meets certain selection criteria can be transformed
into queries that can be processed by a matchmaking engine that is aware of the relevant domain ontologies and Web services. We also describe how user-specified preferences for Web services in terms of non-functional requirements (e.g., QoS) can be incorporated into the Web service discovery mechanism to generate a partially ordered list of services that meet user-specified functional requirements.
