CMNA 2012 - 12th workshop on Computational Models of Natural Argument

The series of CMNA workshops, since its inception in 2001, has been acting to nurture and provide succor to the ever growing community working in “Argument and Computation”.
AI has witnessed a prodigious growth in uses of argumentation throughout many of its subdisciplines: agent system negotiation protocols that demonstrate higher levels of sophistication and robustness; argumentation-based models of evidential relations; 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.
