摘　　要：在Web服务描述语言（WSDL）与网络服务的本体语言（OWL-S）共存的环境中难以实现Web服务混合组合,为此提出一种以接口自动机为基础的混合Web服务组合方法.分析和描述WSDL与OWL-S间的关系后,在服务组合过程中用接口自动机实现WSDL与OWL-S自动识别和组合;并将服务组合结果与预先设定好的服务质量进行优化对比,选择服务质量最优的来实现不同的业务逻辑.最后通过一组旅游消费服务实验分析验证表明,该方法可行、有效,服务组合效率提高了5％～10％.To realize hybrid Web service composition when Web Services Description Language （WSDL） and Web Ontology Language for Service （OWL-S） coexist, an approach based on interface automata was presented. Firstly, the interface automata were employed to accomplish automatic recognition and composition of Web services after analyzing the relations between WSDL and OWL-S. Simultaneously, the optimal results were obtained to realize different service business logic by comparing the service composition with the predefined service quality. The results of a tourism service sample show that the approach is feasible and effective, and the efficiency of service composition is improved by 5% - 10%.
