近年来，Web服务组合的研究引起了学术界和工业界的广泛关注。相关的研究项目和原型平台也在开发中。我们已经实现了半自动的服务组合与工作流技术相结合的业务流程执行语言Web服务和过程本体。我们提出了一种方法，利用过程本体的Web服务的半自动组合。该方法利用过程本体描述过程中的不确定部分，而确定部分则用过程本体描述。在本文中，我们提出了一个灵活的框架，Web服务组合，其中包括服务组合模型和服务组合执行。前者主要包括Web服务的发现、组合和验证，后者包括Web服务的组合、合成和执行。基于这种方法的框架已经成功地在DartFlow项目中实现。
Recently, research on Web services composition has attracted a lot of attentions from both academic and industry. Related research projects and prototype platforms are also been developed. We have implemented the semi-automatic services composition with workflow technology which combines Business Process Execution Language for Web Services with process ontology. We propose a method for semi-automatic composition of Web services using process ontology. This method describes unfixed part of a process by process ontology, The fixed part is described by BPEL. In this paper, we propose a flexible framework for Web services composition which consists of services composition model and services composition execution. The former includes mainly Web services discovery, composition and verification, the latter includes Web services composition composer and execution. A framework based on this approach has been successfully implemented in the DartFlow project.
