中文摘要： 本课题依托项目组之前在服务计算领域的研究成果，探索从业务流程的角度去研究服务及演化过程，围绕服务与之所处业务流程的关系，开展服务的划分、推荐和治理的研究。通过研究服务组合的历史并采用关联规则挖掘分析服务依存关系，并在此基础上依靠层次分析法逐步抽取服务候选单元。为了将合理划分的服务更好地参与到业务流程中，在关联规则分析的基础上，提出了隐式服务偏好评分方法，利用改进的协同过滤方法实现服务的推荐。同时，进一步研究服务随着业务改变而不断演化的生命周期管理机制，引入可量化的利益相关人分析框架，使得服务始终能够与所涉及的业务流程保持关联性，确保服务始终处与一个合理的粒度。具体研究内容包括：1）基于业务流程的服务划分技术；2）面向业务规则的服务推荐技术；3）基于利益相关者的服务治理技术，并最终搭建一个面向业务流程的服务综合管理原型系统，验证方法和技术的有效性。

英文摘要： SOA is a very important mechanism to support flexible business process. In this research, inspired by the relationship between service and business process, comprehensive analysis is conducted from viewpoint of service and its evolution with regard to the business process. Particularly three objectives are identified, i.e., service identification, service recommendation and service governance. First the association rule is employed to describe the inter-dependency among services, based on which a semantic analysis is utilized to describe the dependency among services. Afterwards service identification is realized by using clustering methods. After service is identified, the next important task is to properly recommend it to the users. In this research, the recommendation process uses the implicit selection ratio of services on particular process as a preference hints. And then a collaborative filtering based re-raking mechanism is designed to support appropriate service recommendation. Furthermore, since business is always changing from time to time, it becomes necessary for the service to evolve gradually accordingly. In this research, a service lifecycle management framework is discussed to support service evolution to make sure the service is always consistent with the requirement of business process. As such the main research objectives are as follow: 1) business process aware service identification; 2) business constraint oriented service recommendation; 3) stakeholder based service evolution and management. Finally a prototype of for service governance supporting service identification and recommendation will be conducted and case study and field study will be included for validating the proposed mechanism.
