摘要
单个Web服务提供的功能有限,服务组合成为Web服务应用的一个重要研究方向。提出了一种基于与或图的语义服务自动组合方法。该方法为Web服务引入语义,能将服务搜索空间受限于服务组合与或图中,并能从服务组合与或图中选出最佳组合图,从而达到优化服务组合的目的。仿真实验证明,该方法提高了Web服务组合的成功率和效率。
Single Web service just provides limited functionality, Web services composition has become an important research aspect in Web services application domain. This paper proposed an approach based on AND/OR graph to compose semantic Web services automatically. It adds the semantics to Web services and has a smaller search space limited to the service composition AND/OR graph and it finds the best composition graph in the service composition AND/OR graph to achieve the purpose of optimizing services composition. The results of the extensive experiments show that this method improves both the successful and the efficiency ratio of Web services composition.
