The construction of reducts, that is, minimal sets of attributes containing the main information
of a database, is a fundamental task in different frameworks, such as in Formal Concept …

Abstract Knowledge reduction is one of the key issues in formal concept analysis and there
have been many studies on this topic. The irreducible elements in a lattice are also very …

This paper considers the introduced relations between fuzzy property-oriented concept
lattices and fuzzy relation equations, on the one hand, and mathematical morphology, on the …

Information extraction from an L-fuzzy context becomes a hard problem when we work with a
large set of objects and/or attributes. The goal of this paper is to present two different and …

Abstract Objects and attributes play an important role in an L-fuzzy context. From the point of
view of the L-fuzzy concepts, some of them can be more relevant than others. Besides, the …

In this work, we consider a complete lattice L and we study L-fuzzy context sequences which
represent the evolution in time of an L-fuzzy context. To carry out this study, in the first part of …

In this paper we extend some previously established links between the derivation operators
used in formal concept analysis and some mathematical morphology operators to fuzzy …

In this paper we study the relation between L-fuzzy morphology and L-fuzzy concepts over
complete lattices. In particular, we show how the erosion and dilation operators of the former …

We define the randomized fuzzy formal context using the random variables with a normal
distribution and explore the one-sided formal concept stability. Since the modified Rice-Siff …
