A framework for semantic Web Services annotation and discovery based on ontology

In order to achieve the automatic discovery of Web Services to composition, business processes and workflows, it is necessary to take advantage of semantic information. A couple of approaches have been proposed to achieve automatic annotation and retrieval of Web Services based on similarity or logical reasoning. A key difference between our method and existing methods is that we separated the annotation process from the description documents of services, which can express the semantic explicitly for reusing separately. Meanwhile, we proposed a framework for Web Services discovery automatically based on this annotation method. Finally, we presented the performance for the framework.
