Query for Semantic Web Services Using SPARQL-DL
Hai Wang, Sheping Zhai, Lin Fan · 2009
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.
