Goal of the Project

This project is a successor to the project Abstract Dialectical Frameworks: Advanced Tools for Formal Argumentation, which was on the theoretical foundations of ADFs: we clarified, corrected and generalized the semantics of ADFs; we performed an in depth complexity analysis; we studied dynamic aspects of abstract argumentation; we also did various test implementations. Although theoretical investigations are still at the heart of our research, in this project we will give a lot more emphasis to the development of software tools. An important question we want to address now is the following: how to turn the by now quite well-understood abstract representation formalism of ADFs into easy-to-use tools which help lay users both to specify and to evaluate complex argumentation scenarios and debates.

The objectives of the proposed research are the following:
