Call for Papers, Demos and Workshops

The International Conference on Computational Models of Argument (COMMA) is a regular forum for presentation and exchange of the latest research results concerning theory and applications of computational argumentation. After the successful editions in Liverpool (2006), Toulouse (2008), Desenzano del Garda (2010), Vienna (2012), Pitlochry (2014), Potsdam (2016) and Warsaw (2018), the biennial COMMA event will be hosted by the Department of Mathematics and Computer Science of the University of Perugia. COMMA 2020 will be preceded by the fourth edition of the Summer School on Argumentation (SSA 2020). In addition to the main conference track, COMMA 2020 will include system demonstrations, as well as workshops devoted to specific argumentation-related themes, for both of which we invite proposals.

Please consult the complete Final Call for Workshops, Demos, and Papers (pdf), which also includes the layout, formatting and submission instructions.
