Research on ontology-driven semantic Web services dynamic composition

Because of semantic absence in the traditional web,the services composition efficiency and accuracy are greatly reduced.The Semantic Web overcomes the lack of semantic in the traditional web.Since there exists abundant knowledge in the Semantic Web,it becomes more and more important to effectively utilize these semantics to achieve services composition.In order to solve this problem,this paper presents a dynamic service composition mechanism based on the multidimensional user model.It realizes the sequential and parallel service composition through the semantic matching.Adopting this mechanism will improve the Semantic Web Services composition efficiency and accuracy to some extent.
