Research On Ontology-based SOAP For Semantic Web Services

Along with the Word Wide Web's development, two parallel efforts have emerged in recent years that are Semantic Web and Web services. Ideally, these two efforts support each other. The Semantic Web provides tools for explicit markup of Web content, and Web services create a network in which programs act as independent agents that produce and consume information. In recent years, some efforts have focused on Semantic Web Services (SWS) which combine Semantic Web and Web services.The influential project involved in SWS is OWL-S, which focuses on the ontology of Web service description. It can be applied for service discovery, composition, execution and interoperation. However, the lower layer, such as the Web Services description layer-WSDL cannot express the semantic information defined by OWL-S because it is XML-based; let alone the message layer-SOAP which is the foundational layer of Web Services, since it is XML-based, too. It's well known that XML cannot express semantics and it cannot understand what is being transported, so the Web service description layer and message layer lack semantics. They cannot support the higher layer of...
