Abstract: Two types of consistencies are defined in property oriented concept lattice and three-way property oriented concept lattice, respectively. The relationship between these two types of consistencies is also studied. Then, the?definition?of?decision?rules?and?redundant decision?rules in three-way property oriented concept lattices is introduced, characterization and algorithm of non-redundant rules in three-way property oriented concept lattice are presented. Lastly, the differences and connection of the decision rules between property oriented concept lattice and three-way property oriented concept lattice are further studied in the complement decision formal contexts.

Key words: property oriented concept, three-way decisions, rule acquisition

摘要: 在面向属性概念格和三支面向属性概念格中定义了两种协调性,并研究了两种协调性之间的关系;在三支面向属性概念格中定义了三支面向属性规则及其相应的冗余规则,并给出三支面向属性非冗余规则的刻画和算法;在决策形式背景的补背景下,进一步研究了面向属性规则和三支面向属性规则之间的区别与内在联系。
