摘要
在研究了粗糙近似和形式概念之后,把Roughsets思想应用于FCA中,拓宽了形式概念的范围,对一些特殊的不可定义的概念进行了研究.
After investigating the rough set approximation and the formal concept ,the authors apply the rough set to formal concept analysis. In this paper, the meaning of formal concept is extended. And some special non-definable concepts are discussed.
