ELEVENTH INTERNATIONAL CONFERENCE ON COMPUTATIONAL MODELS OF ARGUMENT (COMMA 2026)

Barcelona, Spain, 16th – 18th September 2026

FIRST CALL FOR PAPERS

https://comma2026.vercel.app<https://comma2026.vercel.app/>

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. This successful series has comprised editions held in Liverpool (2006), Toulouse (2008), Desenzano del Garda (2010), Vienna (2012), Pitlochry (2014), Potsdam (2016), Warsaw (2018), Perugia (2020), Cardiff (2022), Hagen (2024). For 2026, the biennial COMMA event will be hosted 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). In addition to the main conference track, COMMA 2026 will include system demonstrations, as well as workshops devoted to specific argumentation-related themes.

COMMA topics include, but are not limited to:
•     Formal, semi-formal and informal models for argumentation
•     Argumentation and non-monotonic reasoning
•     Dialogue based on argumentation
•     Strategies in argumentation
•     Argumentation and game theory
•     Argumentation and probability
•     Argumentation and narrative
•     Argumentation-based explanation
•     Argumentation and computational linguistics
•     Argument mining
•     Argumentation and large language models
•     Neuro-symbolic computing with argumentation
•     Computational properties of argumentation
•     Reasoning about action and time with argumentation
•     Decision making based on argumentation
•     Argumentation in agent and multi-agent systems
•     Argumentation for coordination and coalition formation
•     Argumentation-based negotiation
•     Argumentation, trust and reputation
•     Argumentation and human-computer interaction
•     Systems for learning through argument
•     Implementation of argumentation systems
•     Tools for supporting argumentation
•     Domain-specific systems using argumentation
•     Innovative applications and tools

We invite submission of original and unpublished work. Parallel submission to journals or other conferences or workshops with published proceedings is not permitted. The conference includes a Regular Track and an Innovative Applications Track. For the latter, we encourage the submission of original papers about innovative applications, e.g., in law, medicine, e-democracy, risk assessment, intelligent user interfaces, recommender systems, argument mining, scientific discovery etc. Innovative applications papers will be assessed in an equally rigorous reviewing procedure as regular track papers. The reviewing process is single blind. The length of each submission, for both Regular and Innovative Applications papers, must not exceed 12 pages.

Paper submission, in PDF format, will be managed through EasyChair (site going live in 2026), with a submission deadline of 18 April 2026 (all dates are 23:59 UTC-12, ‘anywhere on Earth’).

We are delighted that the conference will feature keynote talks from:
•     Guillem Alenyà, Director at the Institut de Robotica i Informatica Industrial at CSIC-UPC, Spain
•     Ulrike Hahn, Director of the Centre for Cognition, Computation and Modelling at Birkbeck, University of London, UK.

The proceedings of the conference will be published by IOS Press as an open-access book. Authors should prepare their submission following the instructions given by IOS Press (http://www.iospress.nl/service/authors/latex-and-word-tools-for-book-authors/).

Important Dates
•     Paper submission open: 23 February 2026
•     Paper submission deadline: 18 April 2026
•     Notification of acceptance: 10 June 2026
•     Camera-ready versions due: 1 July 2026
•     Conference: 16 - 18 September 2026

A separate call will be issued to solicit demonstration of systems and tools, and also proposals for workshops. Details will also be forthcoming of a summer school to be run in conjunction with the conference.

Conference Organisation
•    Program Chair: Katie Atkinson (University of Liverpool, UK)
•    Local Chairs: Vanina Martinez and Lluis Godo (Artificial Intelligence Research Institute IIIA-CSIC, Barcelona)
•    Workshop Chair: Antonio Rago (King’s College London, UK)
•    Demo Chair: Vicent Costa (Artificial Intelligence Research Institute IIIA-CSIC, Barcelona)
