摘要: Web服务组合通过重用已有的Web服务满足用户高质量的应用需求,是面向服务架构研究领域的热点问题。该文对当前Web服务组合的研究现状进行了综述,分析了WSC的概念和实现框架。根据研究侧重点及其依赖的技术基础,将WSC方法归为两大类别——基于工作流、状态演算和进程代数模型描述的过程驱动的组合方法和基于语义描述的自动服务组合方法。对WSC的评价模型及其研究与应用中所面临的挑战进行了论述。

Abstract: Web service composition, as a new technology to fulfill the user’s requirements using existing ones, has become a pop topic in the research of Service Oriented Architecture(SOA). The survey is made on current WSC methods. The concepts and implementing frameworks of WSC are discussed. And based on the research emphases and its dependent technology, WSC methods are classified into process driven WSC such as work-flow based, state-figure and process algebra based methods, and semantics based automatic WSC. The evaluation models and the challenges in research and implementation of WSC have been summarized.

Key words: Service Oriented Architecture(SOA), Web service, Web service composition
