Characterizing One-Sided Formal Concept Analysis by Multi-Adjoint Concept Lattices
María José Benítez-Caballero, Jesús Medina, Eloísa Ramírez‐Poussa · Mathematics · 2022
Managing and extracting information from databases is one of the main goals in several fields, as in Formal Concept Analysis (FCA). One-sided concept lattices and multi-adjoint concept lattices are two frameworks in FCA that have been developed in parallel. This paper shows that one-sided concept lattices are particular cases of multi-adjoint concept lattices. As a first consequence of this characterization, a new attribute reduction mechanism has been introduced in the one-side framework.
