Abstract: The WSMO-MX service matchmaker applies different matching filters to retrieve Semantic Web services written in a dialect of the prominent service description language WSML-Rule. For this purpose, WSMO-MX recursively computes logic-based and syntactic similarity-based matching degrees and returns a ranked set of services that are semantically relevant to a given query. The matching filters perform ontology-based type matching, logical constraint matching, and syntactic matching. In this paper, we present the service description language WSML-MX, the hybrid matchmaker WSMO-MX for WSML services converted to WSML-MX, and the results of our experimental evaluation of its performance in terms of recall and precision over the test collection WSML-TC2.
