The series of workshops on Computational Models of Natural Argument is continuing to attract high quality submissions from researchers around the world. CMNA 1 was held at ICCS in San Francisco in 2001, CMNA 2 was held at ECAI in Lyon in 2002, CMNA 3 was held at IJCAI in Acapulco in 2003, CMNA 4 was held at ECAI in Valencia in 2004, and CMNA 5 was held at IJCAI in Edinburgh in 2005.

Like the past editions, CMNA-6 intends to recognise and consolidate the critical mass that research in the field overlapping Argumentation Theory and Artificial Intelligence has developed in recent years. Potential for exploitation of research in the philosophical theory of argumentation, in informal logic, and in dialectics, have been recognised relatively recently by researchers in artificial intelligence, but already fruits of such cross fertilisation are beginning to ripen. Recent successes include agent system negotiation protocols that demonstrate higher levels of sophistication and robustness; argumentation-based models of evidential relations and legal processes that are more expressive; models of language generation that use rhetorical structures to produce effective arguments; groupwork tools that use argument to structure interaction and debate; computer-based learning tools that exploit monological and dialogical argument structures in designing pedagogic environments; decision support systems that build upon argumentation theoretic models of deliberation to better integrate with human reasoning; and models of knowledge engineering structured around core concepts of argument to simplify knowledge elicitation and representation problems. Furthermore, benefits have not been unilateral for AI, as demonstrated by the increasing presence of AI scholars in classical argumentation theory events and journals, and AI implementations of argument finding application in both research and pedagogic practice within philosophy and argumentation theory.

Areas of Interest

The workshop focuses on the issue of modelling "natural" argumentation. Naturalness may involve the use of means which are more immediate than language to illustrate a point, such as graphics or multimedia. Naturalness can also relate to the preference for one particular style of reasoning as opposed to another to structure complex arguments. Or to the use of more sophisticated rhetorical devices, interacting at various layers of abstraction. Or the exploitation of "extra-rational" characteristics of the audience, taking into account emotions and affective factors. In particular, contributions will be solicited addressing, but not limited to, the following areas of interest:

Submission instructions

The workshop encourages submissions in three categories:

Electronic submissions should be received by one of the organisers no later than 26 March 2006 for long papers, and 23 April 2006 for short papers and demonstration reports.

Extended versions of selected papers accepted to CMNA 1, CMNA 2 and CMNA 3 are to appear in a special issue of the International Journal of Intelligent Systems. Similar avenues will be explored for CMNA 4 and CMNA 5 and CMNA 6.
