Rational Closure for Defeasible Description Logics

In Proceeedings of the 12th European Conference on Logics in Artificial Intelligence (JELIA-10).


Abstract:
In the field of non-monotonic logics, the notion of rational closure is acknowledged as a landmark, and we are going to see that such a construction can be characterized by means of a simple method in the context of propositional logic. We then propose an application of our approach to rational closure in the field of Description Logics, an important knowledge representation formalism, and provide a simple decision procedure for this case.
