Semantics Web service composition engine based on topic maps

Abstract

With regard to the problems like flow control and throughput of Web service composition,a topic-map-based semantics Web service composition engine was proposed,in which some Web services would be described via ontology and topic map.Web services and topic maps were abstracted by using these description languages which included OWL-S and XTM.Web service topic was employed to express semantics Web service,which aimed to use characteristic of topic maps.And topic maps expediently implemented positioning and navigation of information resource,such as Web services,which made states and goal of Web services definite.Thus,to define UDDI registration(UDDIr) and retrieval capability(UDDIs),grammar checking(GD) and semantics recognition capability(SI),similarity(STS),matching(STM),sufficiency(STF) of Web service topics,facet classification capability of Web service topics characteristics(SFC),access right of Web service topics(STP),facet depth decision(FDD) and interoperability capability(STC) to set up service composition engine approach,and employ mathematical method to describe and define.Finally,Java was employed to develop Web service composition engine.The experimental results show that it is feasible and effective.
