A note on similarity relations between fuzzy attribute-oriented concept lattices

摘要

Studying fuzzy attribute-oriented concept lattices has been a challenging issue of Formal Concept Analysis. In [19], the author introduced a fuzzy similarity relation between two collections of L-sets and proved some properties of this similarity type. In this paper, based on a duality technique which allowed us to transfer some properties from antitone to isotone fuzzy concept lattices, we provide alternative proofs for the inequality relations between the similarity of fuzzy attribute-oriented concept lattices and the similarity of the fuzzy contexts.
