Semantic matching for user focused information services selection

To select user focused information services from a service-oriented information system semantically and automatically, a matching approach is proposed in this paper to describe and match the semantics of information services using WSDL-S. The proposed matching approach uses seven QoS factors weighted by user to match requested services with advertised service for more accurate selection. The similarity between the request and the advertisement is computed with semantic ontology. Similar categories of advertisements may be grouped and irrelevant information services may be eliminated from the result set. So user focused information services can be selected by the system semantically.
