Description logic rule and process algebra based OWL-S modeling, matching and composition

A semantic web service modeling, matching and composition methods based on description logic (DL) rule and process algebra is introduced in this paper. It introduces process algebra constructor into DL to figure out OWL-S static and dynamic functional semantic characters, and expands the concept of service semantic matching to support the composability judgments between atomic service and composition process, even between different composition processes. Moreover, composition inference rules based on semantic matching for more general composition structures such as Sequence, Choice, Split, Join and Split+Join etc are also discussed. Therefore, both sequence and parallel web composition can be resolved into reasoning based on semantic matching and composition inference rules mentioned above in DL framework.
