【摘要】：随着互联网技术的迅速发展,越来越多的Web应用出现在人们生活的各个领域。这些独立的Web应用分散在Internet上,实现特定的业务功能,通过浏览器就能方便地进行使用。当开发新的Web应用系统时,若能复用现有的Web应用来组成目标系统,就能实现应用级的软件复用,提高软件开发的效率。在目标系统开发过程中,必须要对待复用的Web应用进行统一的封装,进而能够按照统一的流程构建新的Web应用。然而,现有的技术还不能支持Web应用的组合和交互。构件组装技术是一种将已有的可复用构件遵循特定的组装方案进行组合的技术,组装的结果是一个粒度更大的构件或者是一个完整的应用系统。构件组装技术,是一种很重要的软件复用技术,已经在传统的应用软件开发中发挥巨大的作用。然而,现有的构件组装技术还难以自动组装那些涉及在线人工交互操作的Web应用。为了解决上述问题,本文提出Web应用构件的概念,并提出一种基于OWL-S的Web应用构件及其组装方式的语义描述方案。Web应用可按统一的规范封装为Web应用构件,并基于Web应用构件语义描述方案实现语义化标注,从而使Web应用构件具有语义。用户可根据应用需求按照匹配规则从大量构件中筛选出符合语义描述的Web应用构件。为了优化Web复合应用的开发过程、缩短开发周期、提高Web复合应用的开发效率,本文提出了一种基于语义的Web应用构件组装方法。通过语义描述规则筛选出符合用户特定需求的Web构件,并通过OWL-S到BPMN2.0的映射方案,将描述Web应用构件及其组装方式的OWL-S映射为BPMN2.0文件ojBPM流程引擎加载并解释执行该BPMN文件,从而实现Web应用构件的组装与运行。最后,通过一个旅行规划的实例说明了基于语义的Web应用构件组装方法的应用效果。
[Abstract]:With the rapid development of Internet technology, more and more Web applications appear in every field of people's life. These independent Web applications are scattered on Internet to realize specific business functions. When developing a new Web application system, if the existing Web can be reused to form the target system, the application level software reuse can be realized. Improve the efficiency of software development. In the process of target system development, we must deal with the reuse of Web applications for unified encapsulation, and then can be in accordance with the unified process to build new Web applications. The existing technology can not support the combination and interaction of Web applications. Component assembly technology is a kind of technology to combine the existing reusable components in accordance with a specific assembly scheme. The result of assembly is a more granular component or a complete application system. Component assembly technology is a very important software reuse technology. It has played an important role in the traditional application software development. However, the existing component assembly technology is still difficult to automatically assemble those Web applications involving online manual interaction. In order to solve the above problems. This paper presents the concept of Web application component. A semantic description scheme of Web application component and its assembly method based on OWL-S is proposed. The web application can be encapsulated as a Web application component according to the unified specification. Semantic annotation is realized based on semantic description scheme of Web application component. In order to make the Web application component semantic, the user can screen out the Web application component according to the matching rules from a large number of components according to the application requirements. In order to optimize the development process of the Web composite application, the user can select the Web application component that conforms to the semantic description. . Shorten the development cycle, improve the development efficiency of Web composite application. In this paper, we propose a semantic-based Web application component assembly method, through semantic description rules to screen out the Web components that meet the specific needs of the user. And through the OWL-S to BPMN2.0 mapping scheme. The OWL-S that describes the Web application artifacts and how they are assembled is mapped to the BPMN2.0 file ojBPM process engine to load and interpret the execution of the BPMN file. Finally, an example of travel planning is given to illustrate the application effect of Web application component assembly method based on semantics.
