摘要
提出了概念格的概念背景,在保持概念格中各概念外延不变的情况下,即保持概念背景的论域划分不变的情况下对概念格的属性集进行了约简,提出了概念格启发式属性约简算法,最后通过实例表明了该约简算法的可行性与有效性.
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.
