Agent-oriented Semantic Discovery and Matchmaking of Web Services

The article deals with implementation issues of semantic matchmaking of Web services using intelligent middle agents in an electronic market (e-market). The idea of comparison of Web services according to their semantic descriptions is used to find the most appropriate service that meets user preferences. Comprehensive description of not only the syntax, but also semantic meaning of the service is used to find the most suitable match. Matchmaking procedure is based on DAML-S (DARPA Agent Markup Language for Services) ontology, which contains required semantic information for discovery and comparison as well as execution and monitoring of Web services. In order to find a service that satisfies user requirements, the intelligent software agent semantically compares descriptions of requested and advertised Web services using matchmaking algorithm and automated reasoner based on description logics. This way user will be provided with the most appropriate service that matches his requirements.
