The 26th International Workshop on Computational Models of Natural Argument (CMNA'26)

We are pleased to invite submissions for our forthcoming 26th annual edition of the workshop on Computational Models of Natural Argument (CMNA'26) which will be hosted by the 11th International Conference on Computational Models of Argument (COMMA 2026).

The CMNA workshop series focuses on the issue of modelling “natural” argumentation, where naturalness may range across a variety of forms, perhaps involving the use of visual rather than linguistic means to illustrate a point, for example using graphics or multimedia, or applying more sophisticated rhetorical devices, interacting at various layers of abstraction, or exploiting “extra-rational” characteristics of the audience, taking into account emotions and affective factors.

We also solicit papers concerned with the full range of topics that CMNA usually focusses upon.

Topics

Regular Topics The CMNA workshop series focuses on the general issue of modelling “natural” argumentation. Contributions are solicited addressing, but not limited to, the following areas of interest: The characteristics of “natural” arguments (e.g. ontological aspects, cognitive issues, legal aspects). The linguistic characteristics of natural argumentation, including discourse markers, sentence format, referring expressions, and style. The generation of natural argument.
