Argumentative Agent Deliberation, Roles and Context

Antonis C. Kakas, Pavlos Moraïtis
2002 Electronical Notes in Theoretical Computer Science  
This paper presents an argumentation based framework to support an agent's deliberation process for drawing conclusions under a given policy.  ...  The framework uses roles and context to define policy preferences at different levels of deliberation allowing a modular representation of the agent's knowledge that avoids the need for explicit qualification  ...  For the more general framework with dynamic priorities we apply the same proof theory extended and a derivation is thus split into levels.  ...

An Argumentation Framework Based on Conditional Priorities [chapter]

Quoc Bao Vo
2008 Lecture Notes in Computer Science  
We also establish a sufficient condition for a conditional priority-based argumentation to have a unique stable extension based on the notion of stratification.  ...  Our work reveals some interesting problems to conditional priority-based argumentation and establishes the fundamental properties of these frameworks.  ...  It employs an argumentation framework as the underlying engine for reasoning. This is because the abstract argumentation framework [8] is very generic and flexible.  ...

Using Argumentation Logic for Firewall Policy Specification and Analysis [chapter]

Arosha K. Bandara, Antonis Kakas, Emil C. Lupu, Alessandra Russo
2006 Lecture Notes in Computer Science  
In this paper we propose an approach to firewall policy specification and analysis that uses a formal framework for argumentation based preference reasoning.  ...  The use of a formal framework means that the security requirements defined can be automatically analysed for inconsistencies and firewall configurations can be automatically generated.  ...  Acknowledgements We acknowledge financial support for this work from the EPSRC (Grant Numbers -GR/R31409/01, GR/S79985/01 and GR/T29246/01) and IBM Research.  ...

Layered Strategies and Protocols for Argumentation-Based Agent Interaction [chapter]

Antonis Kakas, Nicolas Maudet, Pavlos Moraitis
2005 Lecture Notes in Computer Science  
This framework was proposed in [6] and developed further in [7] , in order to accommodate a dynamic notion of priority over the rules (and hence the arguments) of a given theory [2, 12] .  ...  In this paper we propose an argument-based framework for representing communication theories of agents that can take into account in a uniform way these different aspects.  ...  We would like to thank Ulle Endriss and the anonymous referees of this paper for their comments.  ...

Modular Representation of Agent Interaction Rules through Argumentation

Antonis Kakas, Nicolas Maudet, Pavlos Moraitis
2005 Autonomous Agents and Multi-Agent Systems  
In this paper we propose an argument-based framework for representing communication theories of agents that can take into account in a uniform way these different aspects.  ...  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  ...  We would like to thank Ulle Endriss and the anonymous referees of this paper for their comments.  ...

GORGIAS: Applying argumentation

Antonis C. Kakas, Pavlos Moraitis, Nikolaos I. Spanoudakis, Federico Cerutti, Richard Booth
2018 Argument & Computation  
The proposed approach is quite general for this type of applications of argumentation and, thus, it can be used with any preference-based argumentation framework.  ...  We briefly review the Gorgias framework and its past applications and present an emerging general methodological approach for developing "decision making" applications of argumentation.  ...  Acknowledgements The authors acknowledge the (partial) support of the project "Societies of Computees" (SOCS IST-2001-32530), carried out under the 5th framework program of the European Union, for the  ...

Nonmonotonic reasoning as prioritized argumentation

Jia-Huai You, Xianchang Wang, Li-Yan Yuan
2001 IEEE Transactions on Knowledge and Data Engineering  
This paper proposes a formalism for nonmonotonic reasoning based on prioritized argumentation.  ...  We argue that nonmonotonic reasoning in general can be viewed as selecting monotonic inferences by a simple notion of priority among inference rules.  ...  In particular, the term prioritized argumentation was rst used by a referee which prompted an investigation that produced Section 2.3.  ...

Reasoning about preferences in argumentation frameworks

Sanjay Modgil
2009 Artificial Intelligence  
The abstract nature of Dung's seminal theory of argumentation accounts for its widespread application as a general framework for various species of non-monotonic reasoning, and, more generally, reasoning  ...  The extended theory preserves the abstract nature of Dung's approach, thus aiming at a general framework for non-monotonic formalisms that accommodate defeasible reasoning about as well as with preference  ...  I would like to thank Martin Caminada for early discussions that inspired development of the ideas in the paper. Many thanks also to Trevor Bench-Capon and P.M.  ...
