      Adaptive agent negotiation via argumentation 

      Kakas, Antonis C.; Moraïtis, Pavlos (2006)
      In this paper, we study how argumentation can be used as a basis for negotiation between autonomous agents, where negotiation strategies of the different parties are represented as argumentation theories within their ...

      Argumentation and temporal persistence 

      Hadjisoteriou, Evgenios; Kakas, Antonis C. (2011)
      We study how the problem of temporal projection can be formalized in terms of argumentation. In particular, we extend earlier work of translating the language E for Reasoning about Actions and Change into a Logic Programming ...

      Hadjisoteriou, Evgenios; Kakas, Antonis C. (2012)
      We study how the problem of temporal projection can be formalized in terms of argumentation. In particular, we extend earlier work of translating the language for ε Reasoning about Actions and Change into a Logic Programming ...

      Argumentation Based Decision Making for Autonomous Agents 

      Kakas, Antonis C.; Moraïtis, Pavlos (2003)
      This paper presents an argumentation based framework to support the decision making of an agent within a modular architecture for agents. The proposed argumentation framework is dynamic, with arguments and their strength ...

      Argumentation Logic 

      Kakas, Antonis C.; Toni, F.; Mancarella, P. (2014)
      We propose a novel logic-based argumentation framework, called Argumentation Logic (AL), built upon a restriction of classical Propositional Logic (PL) as its underlying logic. This allows us to control the application of ...

      Argumentative alternating offers 

      Hadidi, N.; Dimopoulos, Yannis; Moraïtis, Pavlos (International Foundation for Autonomous Agents and Multiagent Systems (IFAAMAS), 2010)
      This paper presents an argumentative version of the well known alternating offers negotiation protocol. The negotiation mechanism is based on an abstract preference based argumentation framework where both epistcmic and ...

      Conflicts resolution with the SoDA methodology 

      Spanoudakis, Nikolaos I.; Kakas, Antonis C.; Moraïtis, Pavlos (2017)
      This paper studies the application of argumentation theory and methods from Artificial Intelligence to the problem of conflict resolution. It shows how the decision theories of each of the parties involved in a conflict ...

      A general framework for argumentation-based negotiation 

      Amgoud, L.; Dimopoulos, Yannis; Moraïtis, Pavlos (2008)
      This paper proposes a unified and general framework for argumentation-based negotiation, in which the role of argumentation is formally analyzed. The framework makes it possible to study the outcomes of an argumentation-based ...

      Modeling data access legislation with Gorgias 

      Spanoudakis, Nikolaos I.; Constantinou, Elena; Koumi, Adamos; Kakas, Antonis C. (2017)
      This paper uses argumentation as the basis for modeling and implementing the relevant legislation of an EU country relating to medical data access. Users can consult a web application for determining their allowed level ...

      Modular representation of agent interaction rules through argumentation 

      Kakas, Antonis C.; Maudet, N.; Moraïtis, Pavlos (2005)
      Communication between agents needs to be flexible enough to encompass together a variety of different aspects such as, conformance to society protocols, private tactics of the individual agents, strategies that reflect ...

      On Argumentation Logic and Propositional Logic 

      Kakas, Antonis C.; Mancarella, P.; Toni, F. (2017)
      This paper studies the relationship between Argumentation Logic (AL), a recently defined logic based on the study of argumentation in AI, and classical Propositional Logic (PL). In particular, it shows that AL and PL are ...

      On the computational complexity of assumption-based argumentation for default reasoning 

      Dimopoulos, Yannis; Nebel, B.; Toni, F. (2002)
      Bondarenko et al. have recently proposed an abstract framework for default reasoning. Besides capturing most existing formalisms and proving that their standard semantics all coincide, the framework extends these formalisms ...

      On the semantics of abstract argumentation 

      Kakas, Antonis C.; Mancarella, P. (2013)
      Arguments need to be judged against other arguments. The decision to accept or reject an argument is generally a global decision that involves examining the same question for other arguments that oppose or can defend the ...

      Tactics and concessions for argumentation-based negotiation 

      Hadidi, N.; Dimopoulos, Yannis; Moraïtis, Pavlos (2012)
      Argumentation-based negotiation has gained increasing prominence in the multi-agent field over the last years. There is currently a long literature on the use of argumentation in negotiation and especially the modeling of ...
