Abstract

This paper shows how the critical questions matching an argumentation scheme can be modeled in the Carneades argumentation system as three kinds of premises. Ordinary premises hold only if they are supported by sufficient arguments. Assumptions hold, by default, until they have been questioned. With exceptions the negation holds, by default, until the exception has been supported by sufficient arguments. By “sufficient arguments,” we mean arguments sufficient to satisfy the applicable proof standard.

Keywords: argumentation schemes, critical questions, artificial intelligence, Carneades system, shifting initiative in dialogue, argument from expert opinion, argument evaluation
