三元背景基于二元关系不变的约简

Reduction based on the binary relations for triadic contexts

针对三元背景,提出了基于二元关系不变的约简问题。根据每个论域中元素对约简所起的不同作用对所有元素进行分类,并对不同类型元素的性质进行讨论。最后研究了约简前后三元概念之间的关系。

Under the framework of triadic concept analysis, the reduction to a triadic context is proposed. According to the roles the elements play in three universes during the reduction process, all the elements are classified into three types, and their properties are given. Finally, the relationship between the triadic concepts and triadic concept lattices before and after reduction are discussed.
