Web services icws 2004 , san diego , ca , usa , june , 2004 , pp . 26 - 34 . 12 benatallah b , sheng q z , dumas m . the self - serv environment for web services composition . ieee internet computing , 2003 , 7 : 40 - 48 以此为出发点，我们在vinca个人服务网格项目中，提出了一种以客户端为核心的计算模型，客户端作为应用调度和执行的控制中心，组织和使用本地及网络资源，为用户提供个性化的问题求解环境。

( 3 ) proposed qos model of service composition template and service recommendation algorithm based on global qos constraint the most service selection arithmetic is aimed at the function and non - function property of one service , our approach is aimed at the global non - function property of composition process and relationship between services , which turn service selection into initiative recommendation 该模型不仅针对单个服务的qos属性进行描述,而且针对整个组合模板qos进行描述,给出了组合模板qos的计算和表示方法,解决了vinca流程中用户无法基于整个流程表达qos约束的问题。再此基础上,给出了基于流程qos约束的服务

To support end - user - programming and reuse composition knowledge , this paper discusses the key problems of how to extract , manage and reuse the composition knowledge in the service - oriented applications , and presents a service composition template based approach to larger - granularity business - level composition knowledge management and initiative recommendation - trybest , the main research work and contribution of this dissertation is described as follows : ( 1 ) proposed a novel approach to service composition knowledge management and recommendation - trybest we introduce the thinking of software reuse into composition knowledge extraction and use ; propose an approach to service composition knowledge extraction by using make use of the technology of case based rule and vinca process 在业务端编程思想和面向最终用户编程的vinca语言已有工作的基础上,从支持最终用户编程、对组合知识复用的角度出发,提出了面向业务用户的基于服务组合模板的大粒度业务级组合知识的管理与主动推荐方法? ? trybest ,通过对服务组合中组合知识的抽取、管理和复用,为最终业务用户主动参与面向服务的应用构造提供支持。主要工作和贡献如下:提出了一种支持复用的服务组合知识管理和主动推荐方法? ? trybest 。

With the approach and the composition logic , we define a service composition knowledge template , which using pattern , quality of service and service resource can configure flexibly . end - users can construct application by configuring the parameter according to their own individuation requirement and realize the service optimal selection by initiative recommendation at runtime . ( 2 ) proposed domain ontology based template selection algorithm and content based service recommendation algorithm we introduce domain ontology into composition template , provide the semantic description with domain ontology , and facilitate the management of composition template 从支持业务用户“编程”的角度出发,充分利用领域专业人员的知识和经验,将其引入到组合知识的抽取和使用中,采用基于案例推理的技术,利用已有的vinca流程,提出了一种基于vinca服务组合的知识抽取方法,利用给定的知识抽取方法,并基于组合逻辑定义了一种使用模式、服务质量和服务资源均可灵活配置、具有行为多态特征的服务组合知识模板,给出了其性质分析和实例化方法。
