摘要： 在分析人类概念形成机理的基础上，提出一种基于对象和属性交叉渐进式概念格生成算法，从空概念格开始，逐个地将形式背景中的对象和属性交叉插入到概念格中，实现对概念格的渐进式构造。该算法能渐进式地有效构造概念格，解决了以往渐进式概念格生成算法针对属性和对象交叉渐增更新需要重新构造概念格的问题。

Abstract: By analyzing the human concept formation, this paper proposes an incremental concept formation approach based on alternate object and attribute. This approach starts from the empty concept lattice, inserts alternately object and attribute of the formal context, and constructs the concept lattice incrementally. The approach can construct incrementally the concept lattice, and avoid reconstructing the concept lattice in view of the attribute and the object alternately increasing.

Key words: concept lattice, incremental algorithm, formal context
