Description
Summary:In this paper, we proposed an improved hybrid semantic matching algorithm combining Input/Output （I/O） semantic matching with text lexical similarity to overcome the disadvantage that the existing semantic matching algorithms were unable to distinguish those services with the same I/O by only performing I/O based service signature matching in semantic web service discovery techniques. The improved algorithm consists of two steps, the first is logic based I/O concept ontology matching, through which the candidate service set is obtained and the second is the service name matching with lexical similarity against the candidate service set, through which the final precise matching result is concluded. Using Ontology Web Language for Services （OWL-S） test collection, we tested our hybrid algorithm and compared it with OWL-S Matchmaker-X （OWLS-MX）, the experimental results have shown that the proposed algorithm could pick out the most suitable advertised service corresponding to user＇s request from very similar ones and provide better matching precision and efficiency than OWLS-MX.
