Argument strength in probabilistic argumentation based on defeasible rules

It is common for people to remark that a particular argument strong (or weak) argument. Having handle on the relative strengths of arguments can help in deciding which consider, regard as acceptable, and present others discussion. In computational models argument, there need deeper understanding strength. multidimensional problem, this paper, we focus one aspect strength deductive argumentation based defeasible logic. We assume probability distribution over language consider how are various ways calculate probabilistic necessity sufficiency premises claim, competing claims. provide axioms characterizing probability-based measures strength, investigate four specific measures.
