Abstract: To make Web service matching more efficient, the irrelevance of generalized semantic of Web service and the current service request was proposed. It was also proved that Web services satisfying the relation could never be matched with the current request. An efficient rule was also proposed to decide whether the relation was satisfied, which means the intersection of generalized semantics of the service and the request is unsatisfied. Based on this rule, the approach to service filtering for service matching was proposed finally. Applications and experiments show the proposed approach is effective to improve the efficiency of service matching.
