CMNA5 at IJCAI, Edinburgh

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, and CMNA 4 was held again at ECAI in Valencia in 2004. Like the past editions, CMNA 5 intends to recognise and consolidate the critical mass that research in the field overlapping Argumentation Theory and Artificial Intelligence has developed in recent years.

AI has witnessed a growth in uses of research in the philosophical theory of argumentation, in informal logic, and in dialectics throughout many of its subdisciplines. 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. Similarly, argumentation theory has benefitted from applied AI work on new tools for teaching and research in argumentation and critical thinking, and from AI problems and issues that have offered a proving ground and evaluation framework for theories of argumentation. The CMNA series is acting to support this community.

Areas of Interest

The workshop focuses on the issue of modelling "natural" argumentation. The need for more "naturalness" has been raised in several occasions, and several interpretations have been given to the attribute. Especially when the human is involved in the loop, arguments which are, for instance, expressed in natural language are definitely more appropriate. But the use of human languages is not the only way to make the reasoning process closer to its addressees. Some researchers have, for instance, acknowledged that the development of the argument itself can take advantages of human reasoning abilities and, among other things, the ability to infer implicit steps of the argument. 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 20 February 2005 for long papers, and 20 March 2005 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.
