【摘要】：考虑到三支概念分析中三支算子可以表达对象集和属性集之间"共同具有"和"共同不具有"这两种语义,基于该理论对混合蕴含规则进行研究.首先定义三支概念分析下的混合蕴含规则,并利用三支算子的性质给出混合蕴含规则成立的充分必要条件;然后根据三支概念的构建算法以及三支概念之间的偏序关系给出三支概念格线图的构建方法;最后,基于三支概念格线图提出混合蕴含规则的获取方法.
[Abstract]:Considering that three operators can express the semantics of "common existence" and "common non-existence" between object set and attribute set in three-branch conceptual analysis, the mixed implication rule is studied based on this theory. Firstly, the mixed implication rule is defined under the three-branch concept analysis, and the necessary and sufficient conditions for the existence of the mixed implication rule are given by using the properties of the three-branch operator. Then, according to the algorithm of constructing three-branch concept and the partial order relation between three concepts, the construction method of three-branch concept lattice graph is given. Finally, the method of obtaining mixed implication rule is proposed based on three-branch concept lattice graph.
