Ontology-Based Heterogeneous Messages Matching in Web Services

The heterogeneity of the messages between Web services is one of the most important problems in the Web services composition. Because of lack effective solution, it reduces the accuracy of service discovery and increases the difficulty of service composition. Thus, a matching method based on ontology is proposed to solve the conflict of heterogeneous messages. This approach uses resource description framework (RDF) graphs to represent service messages, which contains more semantic information than XML language. And a framework was proposed to implement messages matching by name matcher and structure matcher with the aid of the rules repository and the existing match repository. The experiments show that this approach is effective and has well results in the recall and precision.
