A research on automatic component extraction and retrieval method

为了实现适当的软件重用，有必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及时重用，因为这种传统技术以程序源代码为检索单元。本文提出了一种新的基于构件抽取的节目检索系统。我们的系统分析了面向对象程序的集合，获取了面向对象类之间的关系，提取了由若干类组成的可复用软构件。此外，我们的系统为新提取的组件生成由划分的类型名称和注释组成的索引。使用我们的系统，提取的组件可以通过关键字进行搜索，并且可以通过Web浏览器查看结果集，以便用户可以判断查询结果组件是否符合他/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.
