On the interplay between games, argumentation and dialogues
Game theory, argumentation and dialogues all address problems concerning inter-agent interaction, but from different perspectives. In this paper, we contribute to the study of the interplay between these fields. In particular, we show that by mapping games in normal form into structured argumentation, computing dominant solutions and Nash equilibria is equivalent to computing admissible sets of arguments. Moreover, when agents lack complete information, computing dominant solutions/Nash equilibria is equivalent to constructing successful (argumentation-based) dialogues. Finally, we study agentsâ behaviour in these dialogues in reverse game-theoretic terms and show that, using specific notions of utility, agents engaged in (argumentation-based) dialogues are guaranteed to be truthful and disclose relevant information, and thus can converge to dominant solutions/Nash equilibria of the original games even under incomplete information
Strategic Argumentation Dialogues for Persuasion: Framework and Experiments Based on Modelling the Beliefs and Concerns of the Persuadee
Persuasion is an important and yet complex aspect of human intelligence. When
undertaken through dialogue, the deployment of good arguments, and therefore
counterarguments, clearly has a significant effect on the ability to be
successful in persuasion. Two key dimensions for determining whether an
argument is good in a particular dialogue are the degree to which the intended
audience believes the argument and counterarguments, and the impact that the
argument has on the concerns of the intended audience. In this paper, we
present a framework for modelling persuadees in terms of their beliefs and
concerns, and for harnessing these models in optimizing the choice of move in
persuasion dialogues. Our approach is based on the Monte Carlo Tree Search
which allows optimization in real-time. We provide empirical results of a study
with human participants showing that our automated persuasion system based on
this technology is superior to a baseline system that does not take the beliefs
and concerns into account in its strategy.Comment: The Data Appendix containing the arguments, argument graphs,
assignment of concerns to arguments, preferences over concerns, and
assignment of beliefs to arguments, is available at the link

Strategic argumentation dialogues for persuasion: Framework and experiments based on modelling the beliefs and concerns of the persuadee
Persuasion is an important and yet complex aspect of human intelligence. When undertaken through dialogue, the deployment of good arguments, and therefore counterarguments, clearly has a significant effect on the ability to be successful in persuasion. Two key dimensions for determining whether an argument is 'good' in a particular dialogue are the degree to which the intended audience believes the argument and counterarguments, and the impact that the argument has on the concerns of the intended audience. In this paper, we present a framework for modelling persuadees in terms of their beliefs and concerns, and for harnessing these models in optimizing the choice of move in persuasion dialogues. Our approach is based on the Monte Carlo Tree Search which allows optimization in real-time. We provide empirical results of a study with human participants that compares an automated persuasion system based on this technology with a baseline system that does not take the beliefs and concerns into account in its strategy
Negotiating with a logical-linguistic protocol in a dialogical framework
This book is the result of years of reflection. Some time ago, while working in
commodities, the author felt how difficult it was to decide the order in which to
use arguments during a negotiation process. What would happen if we translated the arguments into cards and played them according to the rules of the
Bridge game? The results were impressive. There was potential for improvement in the negotiation process. The investigation went deeper, exploring players, cards, deals and the information concealed in the players´ announcements,
in the cards and in the deals. This new angle brought the research to NeuroLinguistic Patterns and cryptic languages, such as Russian Cards.
In the following pages, the author shares her discovery of a new application for
Logical Dialogues: Negotiations, tackled from basic linguistic structures placed
under a dialogue form as a cognitive system which âunderstandsâ natural language, with the aim to solve conflicts and even to serve peace
