摘　　要：为提高Web服务合成的动态性及降低合成的复杂度,提出了一个基于语义与模板的混合合成框架,并详细分析了基于该框架的抽象服务流程和具体服务流程构建过程。在宏观上,采用工作流及语义模板实现服务合成,并基于服务模板和过程约束设计流程,创建复杂流程以表示现实世界的需求及实现对粗粒度服务合成流程的控制;在微观上,对工作流抽象活动节点实现动态服务合成规划,以减少人工干预,提高服务合成的动态性和自动性。通过宏观、微观间的有机结合,该框架可有效降低服务合成的复杂度,提高合成的可靠性及效率。In order to improve the dynamic capability and reduce the complex degree, a hybrid composition framework based on semantic and template is proposed. The construction of abstract process and concrete process of web services composition are analyzed. Work flow and semantic template are adopted to realize the macroscopical composition of web services and to design the process which is based on the services template and process constraints. Complex process is created to express the requirement of real world and to control the coarse web services composition. The microcosmic composition is realized at the abstract active node and this method can reduce manual intervention and increase the dynamic capability and automatism of services composition. The framework can reduce the complexity of web services composition effectively and improve the reliability and efficiency of web services composition.
