Judgement aggregation in multi-agent argumentation

Edmond Awad, Richard Booth, Fernando Tohmé, Iyad Rahwan
2015 Journal of Logic and Computation  
In addition to identifying fundamental barriers to collective argument evaluation, our results open up the door for a new research agenda for the argumentation and computational social choice communities  ...  We study the problem of how multiple such judgments can be aggregated. We define the problem by adapting various classical social-choice-theoretic properties for the argumentation domain.  ...  Our results on the aggregation of different argument evaluations by multiple agents provide a new approach for conflict-resolution in multi-agent systems.  ...

Combining Social Choice Theory and Argumentation: Enabling Collective Decision Making

Jordi Ganzer-Ripoll, Natalia Criado, Maite Lopez-Sanchez, Simon Parsons, Juan A. Rodriguez-Aguilar
2018 Group Decision and Negotiation  
In this paper, we provide computational infrastructure to support argumentation-based debates, in particular focusing on the problem of how participants in a debate can reach agreement about the outcome  ...  We prove that to ensure that the collective decision is coherent, a property that we think is essential, an aggregation function needs to take into account the dependencies between arguments.  ...  distributed under the terms of the Creative Commons Attribution 4.0 International License (http://creativecommons.org/licenses/by/4.0/), which permits unrestricted use, distribution, and reproduction in  ...

2011 Expert systems with applications  
Nevertheless, solutions such as the Aggregation of Individual Judgements (AIJ) and the Aggregation of Individual Priorities (AIP) do not offer sufficient explanatory data in regards with the final decision  ...  Altogether, the proposed solution enhances the quality of multi-criteria group decision making.  ...  The Aggregation of Individual Judgements (AIJ), and the Aggregation of Individual Priorities (AIP) (Forman & Penitawi, 1998) .  ...

Artificial Intelligence Research for Fighting Political Polarisation: A Research Agenda

Andrea Loreggia, Nicholas Mattei, Stefano Quintarelli
2020 International Forum on Digital and Democracy  
Specifically, we focus on the design of multi-winner voting rules that are both efficiently computable and have provable guarantees on desirable properties such as proportionality and representation.  ...  Political polarization is a growing phenomenon in numerous countries around the world.  ...  In our multi-winner case, switching to the Majority Judgement voting rule does not resolve the problem.  ...

Multi-Agent Decision Problems [chapter]

Pierre Carpentier, Jean-Philippe Chancelier, Guy Cohen, Michel De Lara
2015 Stochastic Multi-Stage Optimization  
It is shown that impulsivity modifies the discount function of each individual, and false consensus effect increases the degree of consensus in a multi-agent decision problem.  ...  Analyzing them together we note that in strategic interactions these two human factors involve choices which change equilibriums expected by rational individuals.  ...  Multi-agent decision problem: consensus and false consensus effect In a multi-agent decision problem an individual needs to take his intertemporal choice considering others' preferences, to the purpose  ...

Embedded ethics: some technical and ethical challenges

Vincent Bonnemains, Claire Saurel, Catherine Tessier
2018 Ethics and Information Technology  
Moreover, we are greatly indebted to Berreby et al (2015) for the way of formalizing ethical frameworks including the Doctrine of Double Effect, and to Cointe et al (2016) for having inspired the judgements  ...  According to preference criteria, the agent selects an action. Another goal of this model is to allow an agent to assess the ethics of other agents within a multi-agent system.  ...  Finally game theory, voting systems or multi-criteria approaches may be worth considering to compare ethical frameworks judgements.  ...

Eliminating Group Agency

Lars J. K. Moen
2021 Economics and Philosophy  
Such groups, group-agent realists argue, are agents in control of their own attitude formation.  ...  In this paper, however, I show how group-agent realism overlooks the important fact that groups consist of strategically interacting agents.  ...  Attitude aggregation An important step in the argument for group-agent realism is showing why satisfying the attitude-to-attitude standards of rationality requires groups to form attitudes that are irreducible  ...

Aggregating Bipolar Opinions (With Appendix) [article]

Stefan Lauren and Francesco Belardinelli and Francesca Toni
2021 arXiv   pre-print
We introduce a novel method to aggregate Bipolar Argumentation (BA) Frameworks expressing opinions by different parties in debates.  ...  By leveraging on recent results on judgement aggregation in Social Choice Theory, we prove several preservation results, both positive and negative, for relevant properties of Bipolar ABA.  ...  When these debates emerge in multi-agent systems [15, 21] , a key question concerns opinion aggregation, namely how we can obtain a collective consensus from several opinions expressed as argumentation  ...

Nikos Karanikolas, Pierre Bisquert, Christos Kaklamanis
2019 Proceedings of the 11th International Conference on Agents and Artificial Intelligence  
There has been also notable research on the combination of Judgement Aggregation, which is one of the main problems in Social Choice, and Argumentation where Pigozzi et al. have extensively studied the  ...  Social choice theory can be applied to multi-agent systems (Endriss, 2014) where voting can provide the classical means for aggregating the individual agents' preferences into a collective decision.  ...  The attacking power for the vote arguments A Rac is less or equal to the attacking power for the vote arguments A Rca , when the majority of agents prefer a over c in the preference profile . 2.  ...
