Abstract: A Web service discovery method based on the click rate index was presented to deal with lower efficiency of query in current semantic Web service discovery methods. By indexing the Web services with higher click-through rate in the universal description discovery and integration repository, we could firstly match the services with a higher access rate in the query process. Experimental results show that the method can guarantee the accuracy and improve the service discovery efficiency obviously.

Key words: Semantic Web service, Index, Service discovery, Click rate
