| Abstract: | 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. |
