Topological Space for Attributes Set of a Formal Context.

Generating concept lattice is investigated for long years. Whether formal concepts and concept lattice can be generated in topological space for objects set G or attributes set M of a formal context F = (G,M,I) is an interesting problem. In this paper, our discussions are concentrated on constructing a topology for M of F , the topology is generated by an approximation space on M . Then there exists one-to-one mapping between the approximation space on M and the topology for M , and it is obtained that attributes of each formal concept is open set in the topological space.
