AIMS AND SCOPE

Argumentation is an exciting research topic in artificial intelligence, with a broad 
spectrum of research activities ranging from theory to applications. The International 
Conference on Computational Models of Argument (COMMA) is a regular forum for presentation 
and exchange of the latest research results related to computational aspects of argumentation. 
After the successful editions in Liverpool (2006), Toulouse (2008) and Desenzano del Garda (2010), 
COMMA 2012 will be held  in Vienna in September 2012.

 	TOPICS

 	 Topics include, but are not limited to:

  * Formal, semi-formal and informal models for argumentation
  * Dialogue based on argumentation
  * Strategies in argumentation
  * Argumentation and game theory
  * Argumentation and probability
  * Argumentation and narrative
  * Analogical argumentation
  * Computational properties of argumentation
  * Reasoning about action and time with argumentation
  * Decision making based on argumentation
  * Argumentation in agent and multi-agent systems
  * Argumentation for coordination and coalition formation
  * Argumentation-based negotiation
  * Argumentation, trust and reputation
  * Argumentation and human-computer interaction
  * Systems for learning through argument
  * Implementation of argumentation systems
  * Tools for supporting argumentation

 	SPECIAL TRACK: INNOVATIVE APPLICATIONS

Next to papers about theoretical results (in the conference's regular track), we encourage 
the submission of original papers about innovative applications,  e.g., in law, medicine, 
e-democracy, risk assessment, intelligent user interfaces, recommender systems. Innovative 
applications papers will be  assessed in an equally rigorous reviewing procedure as regular 
track  papers.

 	DEMONSTRATIONS

 As in the previous edition, a session will be organized for the demonstration of innovative 
working applications and tools. Systems of interest include  (but are not limited to):

 * Innovative applications in law, medicine, e-democracy, risk assessment,
   intelligent user interfaces, recommender systems
  * Argumentation-based reasoners
  * Systems for generating arguments from knowledge bases
  * Systems for editing, presenting and judging arguments and counterarguments
  * Collaborative and social systems based on argumentation
  * Simulations of dialogue-based argumentation
  * Argumentation-based agents and multi-agent systems
  * Decision support systems based on argumentation

 All those intending to demonstrate a system should notify the demonstrations coordinator 
(Adam Wyner). Where a demonstration is not connected to a paper in a track, a two page extended 
abstract about the system should be submitted  for review directly to the demonstrations 
coordinator following the conference style. Accepted extended abstracts will be published in 
the  conference proceedings. For those demonstrations that are connected to a paper in the standard
track or innovative applications track, no separate statement about the demonstration should be 
submitted.

 SUBMISSIONS

 We invite submission of original and unpublished work. Parallel submissions  to journals or other 
conferences or workshops with published proceedings is  not permitted.

 Paper submission will be managed through EasyChair and will be open between March 1 and March 30.

 If you want your paper to be considered for the innovative applications  track, please submit your
 paper via Easychair and also send a message  to the program chair ( b.verheij@ai.rug.nl 
[mailto:b.verheij@ai.rug.nl] ).

 Extended abstracts for demonstrations should be sent directly to the demonstration coordinator 
of the conference, Adam Wyner ( adam@wyner.info [mailto:adam@wyner.info] ).
