Concept characteristic and concept reduction of attribute-oriented concept lattice
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.
