TOAST
The Online Argument Structures Tool

About

The Online Argument Structures Tool (TOAST) is an implementation of the ASPIC+ theory of structured argumentation. Using the text fields below, build an argumentation theory consisting of a knowledge base, rules, contrariness and preferences. Evaluating the theory first translates it into a Dung-style abstract argumentation framework, which is subsequently evaluated for to determine the acceptability of the arguments. More information about the format of the knowledge base and rules can be found on the help page. A RESTful API is also available.
