2011 International Conference on Electric Information and Control Engineering, ICEICE 2011 - Proceedings（2011）
摘要
In the theory of the concept lattices, the structure of a concept lattice is the base of data analysis and is very important. This paper mainly constructs two kinds of new concept lattices using the approximation operators " □ " and " ◇ " respectively. And also studies the relations among new concept lattices, object oriented concept lattice, property-oriented concept lattice and complementary concept lattices.
