On the Inverse Problem for Generalized One-Sided Concept Lattices

Jozef Pócs, Jana Pócsová


Generalized one-sided concept lattices represent a generalization of the classical concept lattices convenient
for analysis of object-attribute models with different types of attributes. Formally, to each objectattribute
model (represented by the notion of formal context) there is assigned a pair of concept-forming
operators. Fixed points of these operators form a hierarchical structure consisting of extent-intent pairs.
From the algebraic point of view this structure forms a complete lattice, called the generalized one-sided
concept lattice. In this paper we deal with the inverse problem for generalized one-sided concept lattices.
For a given generalized one-sided concept lattice we describe an algorithm for finding the corresponding
formal context.
