摘要
概念格是知识处理与分析中的一个有力工具,对它进行约简可以提高效率简化问题。该文在协调决策形式背景下给出了协调集及属性特征的判定定理,并在此基础上得到了一种求属性约简的方法。
The concept lattice is useful in knowledge processing and analyzing.By reducing lattice,it can get the process more efficiently and the work will be simpler.This paper gives the judgement theorems of consistent set and characters of attributes in consistent decision formal context and provides an algorithm to explore the reduction.
