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 builds on three successful workshops:

  • ArgMAS 2006 held in conjunction with AAMAS 2006, at Future University, Hakodate, Japan (attracted 21 participants)
  • ArgMAS 2005 held in conjunction with AAMAS 2005, at Universiteit Utrecht, Utrecht, The Netherlands (attracted 31 participants)
  • ArgMAS 2004 held in conjunction with AAMAS 2004, at Columbia University, New York, USA (attracted 20 participants)
Post-proceedings of previous editions of the workshop have been published in two Springer LNCS volumes:
S. Parsons, N. Maudet, P. Moraitis, and I. Rahwan (Eds.) (2006). Argumentation in Multi-Agent Systems Second International Workshop, ArgMAS 2005, Utrecht, Netherlands, July 26, 2005, Revised Selected and Invited Papers. Lecture Notes in Artificial Intelligence, Volume 4049, Springer-Verlag, Berlin, Germany.
I. Rahwan, P. Moraitis and C. Reed (Eds.) (2005). Argumentation in Multi-Agent Systems: Proceedings of the First International Workshop (ArgMAS'04): Expanded and Invited Contributions. Lecture Notes in Artificial Intelligence, Volume 3366, Springer-Verlag, Berlin, Germany.

The 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 sixth international conference on Autonomous Agents and Multi-Agent Systems AAMAS 2007.


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

Important Dates

Note that the dates are fixed by the AAMAS conference:
Submission Deadline: 5 February 2007
Notification of Acceptance/Rejection: 5 March 2007
Camera Ready Due: 19 March 2007
Workshop: 15 May 2007


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

As done with ArgMAS 2004, ArgMAS 2005, and ArgMAS 2006, 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 would have an ISBN number, and would 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 planned 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 Simon Parsons on parsons@sci.brooklyn.cuny.edu

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