The goal of this paper is to apply this background, particularly to "identify fallacies made by dialogue participants" on the WWW. The Semantic Web is seen as a way to do this.

This paper begins by presenting a definition of argumentation, reviewing Walton's and Toulmin's analyses of arguments, and showing basic argument diagrams. It also discusses the importance, for computer modelling, of classifications of arguments, citing Walton's 1996 book, Argumentation Schemes for Presumptive Reasoning, as the most influential of these. Then, it presents the notion of critical questions and criteria for argument acceptability, which form part of the core basis for this work. Finally, dialogue games are mentioned in passing.
