The First International Workshop on Argumentation and Applications was today!

It was a pleasure to organize the first Arg&App workshop, with Oana Cocarascu, Sylvie Doutre and Antonio Rago. We warmly thank Antonis Kakas who gave an invited talk, and Andreas Niskanen who announced the results of the Fifth International Competition on Computational Models of Argumentation.

Arg&App durign the keynote talk by Antonis Kakas.

During the workshop, I also present two papers:

Abstract Argumentation Applied to Fair Resources Allocation: A Preliminary Study,
A New Evolutive Generator for Graphs with Communities and its Application to Abstract Argumentation.

Graph generators are a powerful tool to provide benchmarks for various sub elds of KR (e.g. abstract argumentation, description logics, etc.) as well as other domains of AI (e.g. resources allocation, gossip problem, etc.). In this paper, we describe a new approach for generating graphs based on the idea of communities, i.e. parts of the graph which are densely connected, but with fewer connections between di erent communities. We discuss the design of an application named crusti_g2io implementing this idea, and then focus on a use case related to abstract argumentation. We show how crusti_g2io can be used to generate structured hard argumentation instances which are challenging for the fourth International Competition on Computational Models of Argumentation (ICCMA’21) solvers.

Abstract Argumentation Applied to Fair Resources Allocation: A Preliminary Study

In this paper, we discuss the application of abstract argumentation mechanisms to resources allocation. We show how such problems can be modeled as abstract argumentation frameworks, such that specific sets of arguments corresponds to interesting solutions of the problem. By interesting solutions, here we mean Local Envy-Free (LEF) allocations. Envy-freeness is an important notion of fairness in resources allocation, assuming than no agent should prefer the resource allocated to another agent. We focus on LEF, a generalized form of envy-freeness, and we show that LEF allocations corresponds to some specific sets of arguments in our argument-based modeling of the problem. This work in progress paves the way to richer connections between the various models of argumentation and resources allocation problems.
