Description Logic Rule Based Semantic Web Service Composition Method

One kind of semantic web service 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 in domain ontology and model web service functional semantic of ServiceProfile, and define service DL rule (R1, R2 and R3) corresponding to sequence, split and join composition structure of GroundProfile respectively. Furthermore, we propose DL rule chain and web service community (WSC) model to describe sequential and parallel service composition, and prove that the semantics of DL rule chain and WSC are all corresponding to a new R1 rule. Furthermore, we give WSC finding algorithm and WSR matching algorithm: the former is to find WSC and DL rule chain by eliminating R2 and R3 rule, the latter is to find some DL rules matching WSR as the composition result. Finally, we analyze the related work and give some experiments to validate the rightness of our method.
