COMMA 2026

Overview

The 11th International Conference on Computational Models of Argument (COMMA 2026) will be held 16–18 September 2026 at the CSIC Delegación de Catalunya, Barcelona, Spain. COMMA 2026 will be preceded by the seventh edition of the Summer School on Argumentation (SSA 2026).

COMMA is a regular forum for the presentation and exchange of the latest research results concerning theory and applications of computational argumentation. In addition to the main conference track, COMMA 2026 will include workshops devoted to specific themes and system demonstrations.

Invited Speakers

• Guillem Alenyà, Director of the Institut de Robòtica i Informàtica Industrial at CSIC-UPC, Spain
• Ulrike Hahn, Director of the Centre for Cognition, Computation and Modelling at Birkbeck, University of London, UK
