Heuristic method for attribute reduction of concept lattice based on Boolean matrix

The improved attribute reduction method based on Boolean matrix of rough set in Reference [6–9] transplanted to concept lattice field. Based on definition of Boolean matrix structural way and the attribute significance of concept lattice, A heuristic method for attribute reduction of concept lattice which save the distinguish attributes between the concept intention and its direct successor intention with Boolean matrix and adopt attribute significance as heuristic information is proposed. Finally, the feasibility and validity of the method are proved with examples.
