Abstract: The representation of Web application pattern gains a considerable momentum with the rapid development of the Internet and Web application. Unfortunately, as Web services are often autonomous and heterogeneous, how to composite them is a delicate and time-consuming task. This paper describes the design and realization of a framework through which existing Web services can be dynamically composed, and the composite services can be executed following a suitable sequence within a dynamic environment. This framework provides tools for specifying composite services through ontology and workflow theory. Consequently, the research efforts related to the work is a valuable attempt to increase the Web application pattern’s flexibility.

Key words: Web service, semantic Web, ontology, workflow

摘要： 随着Internet和Web应用的快速发展，Web应用模式及Web服务的异构和分散问题日益突出，如何复合繁复而庞大的Web服务群成了一项繁杂的工作。该文描述了一个复合语义Web服务框架的设计和实现过程。利用本体模型及工作流技术，该Web服务框架能够动态复合基本Web服务并在动态Web环境下自动执行，提高了Web应用的灵活性，并结合语义Web和工作流理论在提供智能化Web服务方面作了一次新的尝试。
