Probabilistic Strength of Arguments with Structure

Abstract


This paper investigates the relation between abstract and structured accounts of probabilistic argumentation. The ASPIC+ framework is applied to default reasoning with probabilistic generalisations, using the idea that the probability of an argument is the probability of the conjunction of all its premises and conclusions. Based on this idea, two notions of internal and dialectical argument strength are defined and compared. The resulting account is then related to Hunter and Thimm's epistemic approach to abstract probabilistic argumentation.
