摘要 概念格的属性约简是概念格理论研究的一个重要内容,本文给出了概念格中贴近度的定义,并基于贴近度给出了保持概念格中概念外延不变的条件下的启发式属性约简算法。 Attribute reduction is very important in the theory of concept lattices. This paper presents the close - degree of concept lattice and gives an attribute reduction algorithm based on the close - degree. The validity of the algoritLm is shown through a example.
