【 摘 要 】

Service matchmaking is an integral link of service discovery, composition, invocation and other similar task under Service-Oriented Architecture (SOA). Most current approaches measure the degree of match of two service based merely on their I/O pairs which could leads to false result. This paper presents an approach for matchmaking in Semantic Web Services (SWS) that considers each service as a sub-graph of semantic network, which is formed by inputs, outputs, pre-conditions and post-condition, with contribution of syntactical information such as keywords from the service description. Thus the similarity between services is defined as the similarity between two sub-graphs. The aim of this approach is to reveal the internal work flow and intention of services, i.e. behaviors, thus it agrees with human intuition to a larger extent than previous approaches.
