Automatic conceptual indexing of web services and its application to service retrieval

Web service retrieval is a very important issue for making the paradigm of service-oriented computing more practical. In this paper, we develop an automatic conceptual indexing approach of web services and investigate its application to service retrieval at the operation level. Relevant service operations are grouped into the same service concepts using a new variant k-Means algorithmi and with these service concepts, web services can be indexed conceptually. A service retrieving approach, which is supported by the conceptual indexing of web services, is devised to retrieve web services in an efficient way. Experimental results show that the proposed approach greatly improves the performance of retrieving web services.
