一种新的面向对象概念格属性约简方法

摘要

为了研究概念格的属性约简方法，提出了面向对象概念格的可简化属性和不可简化属性，并研究相关性质。给出了面向对象概念格知识约简的判定定理，及相应的面向对象概念格约简方法。本文提出的属性约简方法，不用建立在差别矩阵上面，便可得到形式背景的约简集。%To study attribute reduction in formal concept ,reducible attributes and irreducible attributes are introduced .And the related properties were studied .The judgment theorems of attributes reduction for object-oriented concept lattice are proposed .This is an effective method for reduction in object-orien-ted concept lattice .
