Semantic Web Service Matching Based on Service Hierarchy

A kind of semantic web service matching method based on service hierarchy is proposed, which utilizes the automatic reasoning capability of OWL to construct concept hierarchy and then encodes concept hierarchy in order to transform the complex deduction of inclusion relationship between concepts into simple arithmetic comparison. We give the definition of concepts related with service hierarchy and design the algorithm of constructing service hierarchy. At last, the experimental results show that semantic web service matching based on service hierarchy can respond to service requests in less time and ensure the better quality of service matching than the current semantic web service matching methods.
