摘　　要：In order to realize automatic web service composition, a heuristic web service composition method based on domain ontology is proposed. First, this method integrates the domain ontology and the artificial intelligence （AI） planning algorithm. Then, it uses the domain ontology and its reasoning capability to infer the semantic relationship among parameters. Finally, it transforms the web service composition problem into the planning problem based on the AI planning heuristic algorithm. The preliminary experimental results show that the above method compensates for the lack of semantics in the previous AI planning method and it can satisfy the requirements of quality and efficiency of composition, thus generating composite web services according to customer requirements automatically and efficiently.为了实现web服务的自动组合,提出了一种基于领域本体的启发式算法.该方法将领域本体与人工智能规划方法相结合,利用领域本体及其推理能力,推理出参数间的语义关系,在此基础上运用人工智能规划的启发式算法将web服务组合问题转化为规划问题加以解决.实验结果表明,该方法弥补了以往人工智能规划方法中缺乏语义的不足,综合考虑了服务语义、服务组合质量和服务组合效率等因素,能高效地自动生成满足用户需求的组合web服务.
