This workshop will focus on the concepts, theories, methodologies, and applications of computational models of argumentation in building autonomous agents and multi-agent systems. Argumentation can be abstractly defined as the formal interaction of different arguments for and against some conclusion (eg, a proposition, an action intention, a preference, etc.). An agent may use argumentation techniques to perform individual reasoning, in order to resolve conflicting evidence or to decide between conflicting goals.   Multiple agents may also use dialectical argumentation in order to identify and reconcile differences between themselves, through interactions such as negotiation, persuasion, and joint deliberation.

The main goal of this workshop will be to bring together the community of researchers working on argumentation in multi-agent systems. The workshop has the following technical goals:

  1. To explore the use of argumentation in practical reasoning.
  2. To investigate how argumentation can be used to enable rational interaction between autonomous agents.
  3. To explore the applicability of argumentation for solving a variety of problems in multi-agent systems, such as information exchange, negotiation, team formation, deliberation, etc.
  4. To explore strategic reasoning and behaviour in argumentation-based interaction.
  5. To understand how argumentation relates to other areas of multiagent research, such as game theory, agent communications, and planning.
  6. To present and encourage implemented systems which demonstrate the use of argumentation in 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.

This workshop builds on the following successful workshops (see ArgMAS workshop series web site).


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 these dates are set by AAMAS and cannot be extended.

Submission Deadline: 28 January 2011
Notification of Acceptance/Rejection: 27 February 2011
Camera Ready Due: 7 March 2011
Workshop: 3 May 2011


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

As done with previous ArgMAS workshops, 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

As with previous workshops, each ArgMAS submission will be reviewed anonymously by two members of the expert program committee, who will exercise rigorous standards in evaluating the papers.

Contributors may submit either full papers (no longer than 18 pages) 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

Papers must be submitted through a dedicated EasyChair site, which can be found at:


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