Abstract: Focused on the problems of semantic information lacking and the unappeasable user requirements of the traditional methods for Web service selection,the quantitative QoS properties were used as the heuristic information,and the Web service composition was transformed into the problem of searching and-or-graph in our work.The AO* algorithm was applied to find the optimal Web service last.The simulation results show that the proposed method is effective for the Web service composition and the composition efficiency is enhanced too.

Key words: Semantic Web services,Quality of service,And-or graph,AO* algorithm
