Abstract
Nowadays, the limited function of single Web service can not satisfy the growing and varying custom' s require-ment. Therefore, how to compose Web services automatically according to service request becomes a problem urgent to be solved. This paper proposed an automatic Web service composition method based on planning graph technique, and by estab-lishing precursor-subsequence execution relationship knowledge base to support automatic Web service composition. The meth-od built on automated planning theory and used planning-graph' s expand and search techniques, and could find the service composition solution quickly and automatically. Compared with existing methods, the method took the semantics of Web serv-ices into consideration together with efficiency of the service composition. So the method can ensure quality and efficiency while composing services automatically according to user's service request. Finally using simulation experiment from services composition succeed rate,services composition efficiency and the quality of services composition solution three aspects to vali-date the effectiveness and feasibility of the method.关键词
