The connections between three-way and classical concept lattices
Jianjun Qi,Ting Qian,Ling Wei +2 more
TL;DR: The necessary and sufficient conditions used to construct three-way concepts on the basis of classical concepts are proved, and the algorithms building three- way concept lattices on the based of classical concept lattice are presented.
Journal ArticleDOI
The attribute reductions of three-way concept lattices
Ruisi Ren,Ling Wei +1 more
TL;DR: This paper systematically investigate the attribute reductions of three-way concept lattices which enriches the study of formal concept analysis.
Book ChapterDOI
Three-Way Formal Concept Analysis
TL;DR: A novel concept formation and novel concept lattices are developed with respect to a binary information table to support three-way decisions to provide a new kind of model to make three- way decisions.
Journal ArticleDOI
Relation between concept lattice reduction and rough set reduction
Ling Wei,Jian-Jun Qi +1 more
TL;DR: This paper mainly discusses the relation between concept lattice reduction and rough set reduction based on classical formal context, which will be meaningful for the relation research between these two theories, and for their knowledge discovery.
Journal ArticleDOI
Three-way dual concept analysis
TL;DR: A novel type of three-way concept lattices is presented based on dual concept analysis, which enables ones to characterize specific set by pointing out the attributes that are not possessed by at least one object in the complement of this specific set.
