The 7 th International Semantic Web Conference Service Matchmaking and Resource Retrieval in the Semantic Web ( SMR 2 2008 )

In this paper, we present an approach to hybrid semantic Web service selection of semantic services in SAWSDL based on logicbased matching as well as text retrieval strategies. We discuss the principles of semantic Web service description in SAWSDL and selected problems for service matching implied by its specification. Based on the result of this discussion, we present different variants of hybrid semantic selection of SAWSDL services implemented by our matchmaker called SAWSDL-MX together with preliminary results of its performance in terms of recall/precision and average query response time. For experimental evaluation we created a first version of a SAWSDL service retrieval test collection called SAWSDL-TC.
