摘要
提出面向属性概念协调集和概念约简,定义了包含补二元关系的面向属性概念极小集,讨论了面向属性概念格中核心概念、相对必要概念及不必要概念的概念特征,并研究了三种概念的判别方法.给出了面向属性概念约简的可行方法及其相应算法.
Abstract
The attribute-oriented concept coordination set and concept reduction are proposed,and the attribute-oriented concept minimal set with complementary binary relation is defined.The concept characteristics of core concepts,relatively necessary concepts and unnecessary concepts in attribute-oriented concept lattice are discussed,and the discriminating methods of three concepts are studied.The feasible method and corresponding algorithm for attribute-oriented concept reduction are given.
