摘要
基于信息概念格,给出了信息形式背景下协调集的判定定理.同时区分了在信息概念格属性约简中起不同作用的属性,给出了各类属性的特征和判别方法.
Judgment theorems of consistent set in information formal context based on information concept lattices are dealt with in this paper. At the same time, different kinds of attributes which play different roles during attribute reduction in information concept lattices are distinguished. Characteristics and judgment theorems of all kinds of attributes are also given.
