A Computational Model of Pragma-dialectics as a Tool for its Analysis and Evaluation

Alejandro Secades

Abstract


The overall goal of this paper is to show that computational modelling of argumentation theories is a useful tool to deepen them. Specifically, it provides a basic computational formalization of part of Pragma-dialectics’ model of a critical discussion, which serves as a basis for analyzing this influential theory of argumentation. Such analysis reveals some weaknesses and leaves some questions opened for Pragma-dialectics. Particularly, it shows that the model of a critical discussion is not independent of the model of reasoning/inference chosen, because, while it performs differently with different models of reasoning, it does not work well with some of them.
