Extended multi-adjoint logic programming
M. Eugenia Cornejo, David Lobo, Jesús Medina
Extended multi-adjoint logic programming arises as an extension of multi-adjoint normal logic programming where constraints and a special type of aggregator operator have been incl…
Bipolar fuzzy relation equations systems based on the product t-norm
M. Eugenia Cornejo, David Lobo, Jesús Medina
Bipolar fuzzy relation equations arise as a generalization of fuzzy relation equations considering unknown variables together with their logical connective negations. The occurrenc…
Impact of local congruences in variable selection from datasets
Roberto G. Aragón, Jesús Medina, Eloísa Ramírez-Poussa
Formal concept analysis (FCA) is a useful mathematical tool for obtaining information from relational datasets. One of the most interesting research goals in FCA is the selection o…
Reducing concept lattices by means of a weaker notion of congruence
Roberto G. Aragón, Jesús Medina, Eloísa Ramírez-Poussa
Attribute and size reductions are key issues in formal concept analysis. In this paper, we consider a special kind of equivalence relation to reduce concept lattices, which will be…
Syntax and semantics of multi-adjoint normal logic programming
M. Eugenia Cornejo, David Lobo, Jesús Medina
Multi-adjoint logic programming is a general framework with interesting features, which involves other positive logic programming frameworks such as monotonic and residuated logic…
