AB - This paper is concerned with the problem of quantifying the strengthof arguments in controversial debates, which we model as abstract argumentationframeworks [Dung, 1995]. Standard approaches to abstract argumentation provideonly a qualitative account of the status of arguments, whereas numerical measuresof argument strength might provide a more precise evaluation of their individualstatus. Intuitively, the strength of an argument in a debate essentially depends onhow a proponent of that argument would defend himself against the criticisms ofsomeone opposed to the argument. Since there can be many ways of defending andattacking an opinion, we essentially conceive argument strength as an equilibriumresulting from the interactions taking place between the opinions that a proponentand an opponent of the argument could a priori embrace. More formally, we defineargument strength in terms of the value of a repeated two-person zero-sum strategicgame with imperfect information. Then, using the game-theoretic properties ofsuch games and notably the von Neumann minimax theorem [Neumann, 1928], weestablish and illustrate the main properties of this new argument strength measure.
