This little application can be used for easily and quickly computing extensions of an abstract argumentation framework (AF), under most classical extension-based semantics. It can be used for educational purpose (e.g. letting students easily compare the outcome of different semantics on the same AF, or comparing the outcome of the same semantics on slightly different AFs), or for quickly checking that your examples are correct when you include it in a research paper :)

The AF reasoning engine is Tweety.

This first version of the application was quickly developped a long time ago, and there are many options for improving it, e.g. taking into account enriched models (incomplete AFs, preference-based or value-based AFs,...), adding a graph visualization,...

Feel free to contact me for any remark, question, or collaboration proposal :)
