| 摘 要： | 服务组合是一种重要的服务应用形式，为服务重用与自动化集成提供了支撑。传统服务组合方法依赖基于关键字的查找，缺乏服务语义的分析，且现有服务组合算法往往未考虑QoS的因素。文章将语义本体和QoS结合起来，共同作为Web服务选择和组合的条件，以提高服务组合的质量和组合结果的执行效率。仿真实验结果显示出该方法较传统组合方法能够获得更好的组合结果，使应用的服务性能得到改善。

| Abstract: | Web services composition is an important form of service application,which provides support for service reusing and automatic integration.Traditional Web service composition that depends on keyword selecting lacks semantic analysis.And existing methods of web services composition do not take QoS factors into consideration.In the paper,semantic ontology and service QoS are combined together,which are used as criteria for web services selections and compositions.So the high quality of service composition coul... |
