A research on automatic component extraction and retrieval method

为了实现适当的软件复用，需要寻找满足给定需求的软件。然而，传统的搜索技术不能实现软件的快速重用，因为这种传统的技术的目标是作为检索单元的程序源代码。在本文中，我们提出了一个新的组件提取为基础的程序搜索系统。我们的系统分析了一个面向对象（OO）程序的集合，获取OO类之间的关系，并提取可重用的软件组件组成的一些类。此外，我们的系统生成的索引组成的划分类型名称和新提取的组件的意见。使用我们的系统，提取的组件可以搜索的关键字，结果集可以通过Web浏览器查看，这样用户就可以决定是否查询结果组件匹配他/她的要求。

To realize appropriate software reuse, it is necessary to seek software that satisfies a given requirement. However, conventional search techniques can not realize prompt reuse of software because such conventional techniques target the program source code as the retrieval unit. In this paper, we propose a new component-extraction-based program search system. Our system analyses a collection object-oriented (OO) programs, acquires relationships among OO classes, and extracts reusablee software components composed of some classes. Moreover, our system generates indexes composed of divided type names and comments for newly extracted components. Using our system, the extracted components can be searched by keywords, and the result set can be viewed by a web browser such that the user can decide whether the query result component matches his/her requirements.
