A novel semantic Web service composition algorithm based on QoS ontology

With the development of Internet and information sharing, semantic web attracts many re-searchers´ attention in computer field. Web service composition is an important technology in domain of Web service. As integrated solution for realizing the vision of the next generation of the web, semantic web services combine the semantic web technology with web service technology, and thus enable automated discovery, selection, composition and execution of web services. Ontology is the theoretical foundation of semantic web services. Qos ontology of web services description is introduced. In this paper, a new composition algorithm of semantic Web service based on QoS ontology is proposed. Experiments are carried out to compare the new algorithm with some other web service composition algorithms.
