面向属性归纳和判定树的结合及其在软构件查询中的应用

Application in Software Reuse Based on the Integration of AOI and Decision Tree

构件的复用是软件复用的主要形式,大批的构件必须用一个数据库进行管理,如何从构件库中查询满足条件的构件是构件库系统的研究重点之一.数据挖掘技术为解决上述问题提供了一条可行的途径.利用数据挖掘技术中的面向属性归纳(attribute-oriented induction,AOI)对数据挖掘集进行处理得到初始工作关系,再利用判定树(decision tree)对初始工作关系进行数据概化,从而将两种方法结合起来在构件库中快速、有效地查找到有用的构件信息.通过对数据挖掘技术的应用,为复用者理解和选取构件提供了一定程度的辅助判定支持.

Component reuse is the main form of software reuse. A large amount of components must be managed in a database, to retrieve the most satisfying component among the library of components plays a key role in component library system. Data mining technologies provide a feasible approach for effective decision support. In this paper, the set of mining data is turned into the set of beginning work relation by using AOI, then, to generalize the data of the beginning work relation with decision tree. The integration of AOI and decision tree is discussed, with which we can find useful information of component quickly. Solutions improved possibility and quality of reuse.
