Resumen:
In this paper we present an embedding of abstract argumentation systems into the framework of Barwise and Seligman s logic of information flow. We show that, taking P.M. Dung s characterization of argument systems, a local logic over states of a deliberation may be constructed. In this structure, the key feature of non-monotonicity of commonsense reasoning obtains as the transition from one local logic to another, due to a change in certain background conditions. Each of Dung s extensions of argument systems leads to a corresponding ordering of background conditions. The relation among extensions becomes a relation among partial orderings of background conditions. This introduces a conceptual innovation in Barwise and Seligman s representation of commonsense reasoning.
