| 摘 要： | 扩展概念格是作者在Galois格中引入等价内涵关系而得到的一种扩展形式,并且已对其渐进式构造进行了研究。文章针对已构造好的扩展概念格,在数据对象删除时如何维护的问题,提出了一种算法,经验证是有效的。

| Abstract: | Authors have presented Extended Concept Lattice by introducing equivalence relation between intensions to Galois Concept Lattice and studied its incremental algorithm.This paper proposes an maintaining algorithm for built Ex-tended Concept Lattice and its corresponding graph when some object is deleted from context.Results of empirical test shows that it is efficient. |
