摘要: 为了实现Web服务合成的自动化、高效化,给出了一种支持语义的Web服务合成算法。该算法首先利用本体的推理功能实现可用服务集的构造,其次采用分步法进行服务合成图(WebServiceCompositionGraph,WSCG)的构造,最后通过图的搜索技术实现合成方案的选择,经实验测试表明该算法具有良好的合成效率和成功率。

Abstract: To achieve the automation and efficiency of Web Service composition, the dissertation presents a new semantic-based Web Service composition algorithm, which makes full use of the graph theory knowledge and ontology reasoning function. Firstly, the set of services available is constructed using ontology reasoning function. Then, service composition graph Web Service Composition Graph (WSCG) is constructed by sub-step. Finally, the solution of Web Service composition is selected using graph searching algorithm. It′s proved that the method has a good success rate and efficiency.
