Overview

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 2007 held in conjunction with AAMAS 2007, in Honolulu, Hawai'i, USA (attracted 22 participants)
• 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)

Publication

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

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

Papers must be submitted through a dedicated EasyChair site, which can be found at: http://www.easychair.org/conferences/?conf=argmas2008

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