Abstract: Concerning the dispersibility and uncertainty of Service-Oriented Computing (SOC), as well as the bottleneck of service discovery, selection and composition in technology and application, an approach of topic map service composition was proposed. It employed description logic to merge topic map and Web services, and a topic map semantics Web service was got by using ontology to achieve the description between topic map and Web services in merging. Tableau decision algorithm based on SHOIQ was adopted to accomplish topic map semantics Web service composition. The case analysis shows that the method is feasible and effective.
