摘　　要：Web服务是近年发展的一种分布式技术,引起了越来越多研究者的关注。随着网络上Web服务技术描述的信息系统数量的不断增加,将现有的业务流程进行组合以满足较为复杂的业务系统成为当前发展的主要趋势。此外,由于Web服务所处环境的复杂性和动态性,使得Web服务组合任务变得非常困难。因此,Web服务组合逐渐成为语义Web服务领域研究的热点和难点。描述了一个基于OWL-S和HTN的Web服务组合框架,并详细介绍了如何利用HTN规划解决Web服务组合问题的算法思想。通过学生选课服务实验,验证了该方法的可行性。Web services is a distributed technology and have developed in recent years, paid more and more attention to researchers. As the increasing number of information systems in the network described by Web services technology, the combination of existing business processes to meet the more complex ones has become the main trend of development. In addition, because of the complexity and dynamic nature of the Web services environment, Web service composition makes it a very difficult task. So Web service composition has become a hot and difficulty in the field of semantic Web services. This paper describes a Web ,service composition framework based on OWL-S and HTN and details the algorithm idea of how to use HTN planning to solve the problem of Web service composition. Finally, the course selection service of students is imolemented to demonstrate the feasibility of the method.
