摘　　要：在面向应用的服务组装平台中,服务匹配是服务组装的重要前提。分析现有服务匹配模型,在异构服务统一描述的基础上,提出适合于异构服务组装平台的服务匹配模型。该模型由功能匹配和非功能匹配(服务质量匹配)两阶段组成,引进具有替代性质的相似函数来度量服务的功能相似程度,并采用可扩展的QoS模型选择质量最优者,能从查全率和查准率两方面提高服务检索的质量。In the application - oriented services composition platform, service matching is an important prerequisite for services composition. In this paper, the existing service matching model were analyzed. Furthermore, a service matching model, which fit for heterogeneous services composition platform, were proposed on the basis of unifying description of heterogeneous services. This model features functional matching and non- functional matching （QoS matching） two parts. Similarity functions which have substitute nature were introduced to measure the functional similarity of services and scalable quality of service model was proposed to choice the optimum one. It can improve the quality of service matching from the rate of recall and precision.
