| 摘 要： | 从拓扑的角度研究形式背景的属性约简问题。对于非决策形式背景,提出基于集合交集的属性约简的新的定义,并得出了交协调集的判定定理,证明了交协调集与概念格协调集是等价的;最后,讨论了带有决策的形式背景的属性约简问题。

| Abstract: | Attribute reduction in formal context is proposed in terms of topology. Firstly, a new definition of attribute reduction in formal context is proposed, and an approach to such attribute reduction is constructed. Furthermore, the connection between meet-reduction and concept lattice-based reduction is discussed. Finally, attribute reduction in consistent decision formal context is explored. |
