Semantic Web Service Modeling and Composition Based on Description Logic Rule

One kind of semantic Web service modeling and composition method based on description logic (DL) rule is introduced in this paper. We use DL rule to figure out the hyponymy relationship between concepts of domain ontology and model Web service functional semantic of ServiceProfile, and define service DL rule to describe semantic matching of atomic Web service. Furthermore, we propose DL rule chain to describe semantic Web service composition, and prove that its semantic is corresponding to a new DL rule. Moreover, we give DL rule chain finding algorithm and WSR matching algorithm to find the composition result. Finally, we generate a dataset to test two algorithms above and show perfect execution efficiency.
