On intent stability index for one-sided concept lattices
TL;DR: The intent stability index represents an useful relevancy measure of the extracted patterns in the FCA data mining method for the so-called one-sided concept lattices, which represent a fuzzy generalization of the classical FCA.

Influences of Three-Way Concept Lattice Caused by Variations of Attribute Values
Huilai Zhi,Shulin Hu +1 more
TL;DR: The influences of three-way concept lattices caused by variations of attribute values are explored and two types of changes are discussed, including changing the value of a specific incidence relation from 0 to 1, and the other is from 1 to 0.

Restructuring lattice theory: an approach based on hierarchies of concepts
TL;DR: Restructuring lattice theory is an attempt to reinvigorate connections with the authors' general culture by interpreting the theory as concretely as possible, and in this way to promote better communication between lattice theorists and potential users of lattices theory.

Concept lattices and order in fuzzy logic
TL;DR: A theorem is presented characterizing the hierarchical structure of formal fuzzy concepts arising in a given formal fuzzy context, Dedekind–MacNeille completion of a partial fuzzy order and results provide foundations for formal concept analysis of vague data.

Bipolar fuzzy sets and relations: a computational framework for cognitive modeling and multiagent decision analysis
TL;DR: It is proved that /spl alpha/-level fuzzy number-based bipolar operations can be converted to interval-based and then real-valued bipolar operations and the conversions lead to significant computational simplification on bipolar fuzzy relations.
