Automatic Service Matching and Service Discovery Based on Ontology

With the development of standards and technologies related to services, more and more services are becoming available on the Internet. To find a target service from tremendous ones, which provides the wanted functions, has become more and more difficult. Thus automatic service matching and service discovery become important. In order to realize the automatic service matching and service discovery, ontology is the key solution. In this paper, we use ontology to describe services and use ontology to compute the similarity between two concepts. Based on the computation of ontology, we propose algorithms to search target services based on ontology information embedded in them. Our algorithm cares about not only the relationship between ontology classes, but also the relationship between classes and properties. Thus it provides more accuracy than other related methods.
