Solving the Frame Problem

Vladimir Lifschitz

University of Texas at Austin

The frame problem is the problem of formalizing the "commonsense law of inertia," which asserts that properties of the world tend to remain unchanged as time goes by. This is an important problem in the area of knowledge representation -- the part of Artificial Intelligence that deals with representing declarative knowledge in formal languages. In this talk, I will outline a solution to the frame problem, proposed by Norman McCain and Hudson Turner, which is based on a nonmonotonic causal logic.
