Parametrized Logic Programming
CENTRIA seminar: Parametrized Logic Programming
Wednesday, 20th of October 2010, 14h00
FCT/UNL, Seminar Room (Ed. II)
Traditionally, a logic program is built up to reason about atomic first-order formulas. The key idea of parametrized logic programming is that, instead of atomic first-order formulas, a parametrized logic program reasons about formulas of a given parameter logic.
We define semantics for such general programs and prove results that can be instantiated for every particular choice of the parameter logic.
We show that some known approaches in the literature of logic programming, such as paraconsistent answer-sets and the MKNF semantics for hybrid knowledge bases, are obtained as particular choices of the parameter logic.
Ricardo Gonçalves is a Post-doc researcher at CENTRIA. His work is now focused on the problem of combining rules and ontologies for the Semantic Web. He holds a PhD in Mathematics from the Technical University of Lisbon within the subject of Abstract Algebraic Logic.
