| Abstract: | The concept background is proposed,based on the fact that the paper presents a new heuristic attribute reduction algorithm of concept lattice.The algorithm keeps the extent of every concept unchanged.The validity of the algorithm has been tested by an example,and results show that the algorithm is efficient for attribute reduction of concept lattice. |
| Keywords: | concept lattice concept background attribute reduction |
