An Approach and Implementation to Semantic Web Service Matchmaking

With the growing number of Web Services,the importance of matchmaking and discovery of Web Service is increasing.Using domain ontology to describe the semantic of Web Service and Matchmaking Web Service on the semantic level is a hot research spot.Based on the semantic description of Web Service's Input and Output,the problem of Matchmaking of semantic Web Service is transformed to the calculation of semantic distance between two concepts.Given Web Service requester's demand,different algorithms are applied to calculating the semantic distance of Web Service's Inputs and Outputs.Experiment results demonstrate the enhancement to accuracy and recall.
