Argumentation can be abstractly defined as the interaction of different arguments for and against some conclusion. Over the last few years, argumentation has been gaining increasing importance in multi-agent systems, mainly as a vehicle for facilitating "rational interaction" (i.e., interaction which involves the giving and receiving of reasons). This is because argumentation provides tools for designing, implementing and analysing sophisticated forms of interaction among rational agents. Argumentation has made solid contributions to the practice of multi-agent dialogues. Application domains include: legal disputes, business negotiation, labor disputes, team formation, scientific inquiry, deliberative democracy, ontology reconciliation, risk analysis, scheduling, and logistics. A single agent may also use argumentation techniques to perform its individual reasoning because it needs to make decisions under complex preferences policies, in a highly dynamic environment.

This workshop will be concerned with the use of the concepts, theories, methodologies, and computational models of argumentation in building autonomous agents and multi-agent systems. The workshop will solicit papers looking at both theory and practice. In particular, the workshop aims at bridging the gap between the vast amount of work on argumentation theory and the practical needs of multi-agent systems research.

The workshop will be co-located with the third international conference on Autonomous Agents and Multi-Agent Systems AAMAS 2004.


We solicit papers dealing with, but not limited to, the following areas:

  • Computational models for argumentation
  • Argumentation-based decision making
  • Argumentation-based joint deliberation
  • Argumentation-based persuasion
  • Argumentation-based inquiry
  • Argumentation-based negotiation and conflict resolution
  • Argumentation and risk assessment
  • Argumentation for legal reasoning
  • Argumentation for electronic democracy
  • Argumentation for coordination, cooperation and team formation
  • Argumentation and game theory in multi-agent systems
  • Human-agent argumentation
  • Argumentation and preferences modelling
  • Strategic behaviour in argument-based dialogues
  • Deception, trust, reputation in argument-based interaction
  • Computational complexity of argumentation dialogues
  • Properties of argumentation dialogues (termination, success, etc.)
  • Hybrid argumentation-based models
  • Implemented argumentation-based multi-agent systems
  • New application areas

Preliminary Program


    Argument as Belief-Monitoring
    Prof. Jonathan Adler, Faculty of Philosophy, City University of New York

    Argument is generally conceived as aiming at rational persuasion. However, argument serves another crucial cognitive function: It is a device of belief self-correction. By arguing with an agent, whose judgments I do not control, yet which are coordinated with mine, I can uncover weaknesses in my own beliefs, and weaknesses that I am barred from even recognizing by the very fact of belief. Similarly, perception, memory, simple reasoning, and testimony are generally viewed as reliable ways to acquire good information (new beliefs). But these are also on-going mechanisms to monitor, and so correct or revise, beliefs. I want to explore the value of argument as a second-order monitoring system of self-correction, and for the conceptual and modeling problems this role raises.

Important Dates
Submission Deadline: Thursday 1 April 2004
Notification of Acceptance: Saturday 1 May 2004
Camera Ready Due: Tuesday 25 May 2004
Workshop: Mon 19 July 2004


The proceedings of ArgMAS will be printed and distributed at the workshop.

It is planned to publish revised versions of the accepted full papers in an edited book as part of the Springer Lecture Notes in Artificial Intelligence (LNAI) series. This publication will have an ISBN number, and will be available both in printed form, as well as electronically on the SpringerLink online library.

Submission Procedure

Contributors may submit either full papers (no longer than 5000 words, not including figures) or a two page position statement that outlines their interests, background, and discussion of an aspect of the workshop theme.

Authors are encouraged to submit their papers in the Springer Lecture Notes in Computer Science (LNCS) style, since this will be the format required for the post-proceedings book. Formatting instructions, as well as the style and sample files, can be found here: http://www.springer.de/comp/lncs/authors.html

All submissions should be sent either in PostScript format or in PDF format by email to Iyad Rahwan on

At least one author of each accepted papers must register for the workshop.
