Current Web Service systems are based on "central" UDDI servers and syntactic description of Web Services, which are fragile and unscalable, and do not support Semantic Web Services. It is necessary to replace this UDDI structure with a new one. P2P is such an infrastructure, which allows the sharing of resources and services by direct interaction between equal nodes. Therefore, a discovery...
Automation of semantic web service composition is one of the most promising challenges in semantic web service research area, in which security research on service composition has attracted more attention. In this paper, we present a model of Action labeled Kripke Transition System, namely AKTS which can abstract interaction behaviors involved in service composition and turn them into logic symbols,...
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...
