Current methods of service discovery, using the same mechanism to describe both request and advertisement and does not take into account the asymmetry between the two. Service advertisement discovery is a complete description of descriptive, information-rich features, and service request description is concerned only with some of the characteristics of services, usually does not constitute a complete description of the service. In this paper, we propose to use semantic web query language SPARQL-DL as the service request description language to retrieve OWL-S form published services. Treat the service discovery issue as query against the knowledge base. Through the experiment, confirmed that the method is practical, simple, reliable and easy-to-use.
