Abstract
Semantic Web service (or briefly "SWS") matching is a potential solution for automatic service discovery in various applications such as dynamic and automatic Web service composition. A number of approaches for SWS matching have been proposed. Most of them solely relied on concept subsumption relationship to improve the precision of Web service matching result from lexicalbased methods. However such approaches suffer from several limitations such as not providing a fine-grained service matching degree, not supporting many-to-many matching between operation parameters, and not deriving data mappings between them. In this paper, we introduce a novel method for SWS matching based on SAWSDL, a semantic annotation specification for WSDL. We first define a fine-grained service matching result and then develop a corresponding service matching algorithm which can facilitate many-to-many matching of operation parameters as well as deriving concrete data mappings between them. Semantic techniques are used to infer and match data elements of operation parameters between a request and a service. The proposed algorithm was implemented and applied in the SeTEF - an automatic task-oriented business process execution system. ©2009 IEEE.
