中文摘要	越来越多的企业采用面向服务的架构来构建其信息基础设施,并通过执行Web服务流程来实现其业务逻辑。然而,当前作为工业界标准的服务流程建模语言BPEL4WS只能支持非常有限的运行时动态性,难以适应复杂多变的业务需求。针对这一问题,提出了在BPEL4WS及其执行引擎之上,实现基于语义的服务流程动态细化的机制——在BPEL4WS中增加目标类型的活动以及流程的语义描述；扩展现有BPEL4WS执行引擎使之能够执行带有目标活动的流程,并能够根据目标描述与流程的数据内容,在运行时为目标活动匹配与绑定子流程。; More and more enterprises are adopting the service-oriented architecture to build their information infrastruc- tures and implement their business processes through orchestrating Web services.However,as the current industry stan- dard for business process modeling,BPEL4WS can only provide limited support for runtime dynamics;thus it can not adapt to diverse and rapidly changing business requirements.To address this issue,a semantic-based dynamic process re- finement mechanism based on BPEL4WS and its execution engine was proposed.BPEL4WS was extended via adding a new activity type,referred to as GOAL,as well as a semantic description of business process,referred to as process pro- file.The BPEL4WS execution engine was also extended to execute business processes with GOAL activities,by match- ing and binding a sub-process for a GOAL activity according to the GOAL description and data content.; 国家自然科学基金(90412009)~~
