基于刻面分类模式的构件库检索方法

可复用软件构件的检索是构件库和软件复用领域研究的一个重要课题。基于刻面分类模式的检索方式拥有准确、高效的优势，因而得到了广泛应用。论文介绍了刻面分类模式的相关概念以及刻面树的创建方式，分析了基于刻面分类模式对软件构件库进行检索的规则，该规则将用户选择的刻面和术语通过合理的并和交运算组合生成数据库查询条件来完成检索。最后根据规则提出了相应算法以及刻面分类模式检索在实际构件库系统中的实现方法。

Component Retrieval Method Based on Faceted Classification Scheme

The retrieval of software components is an important issue in the development of component library and research on reusable software. The retrieval technologies based on faceted classification scheme have been widely accepted for its high accuracy and efficiency. This paper introduces the idea of faceted classification scheme and facet tree, analyzes the principles of retrieving components based on faceted classification scheme, which process the facets and terms selected by user and accomplish the condition of data base query by some reasonable union and intersection operations. According to the principles, it proposes an arithmetic and some implementation methods in a real component library management system.
