Call for Papers

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), Warsaw (2018), Perugia (2020), and Cardiff (2022), the biennial COMMA event will be hosted at the FernUniversität in Hagen, Germany. COMMA 2024 will be preceded by the sixth edition of the Summer School on Argumentation (SSA 2024). In addition to the main conference track, COMMA 2024 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
  • 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
  • Demonstrations of innovative working 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We invite submission of original and unpublished work.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. As to 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 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 online at and will be open between 23 February 2024 and 18 April 2024 (all dates are 23:59 UTC-12, ‘anywhere on Earth’).

We also invite submissions of demonstration of systems and tools. Authors of accepted submissions will be invited to present their demonstrations during a special demonstration session. Systems of interest include (but are not limited to):

  • Innovative applications in law, medicine, -democracy, risk assessment, intelligent user interfaces, recommender systems
  • Argumentation-based reasoners
  • Systems for generating arguments from knowledge bases
  • Systems for editing, presenting, and judging arguments and counterarguments
  • Collaborative and social systems based on argumentation
  • Simulations of dialogue-based argumentation
  • Argumentation-based agents and multi-agent systems
  • Decision support systems based on argumentation
  • Argument mining systems
  • Argumentation-based systems for explainable decision making

All those intending to demonstrate a system should notify the demonstrations coordinator Tjitze Rienstra ( by e-mail no later than 04 April 2024, specifying whether the demo is connected to a paper in the main conference track. Where a demonstration is not connected to a paper in the regular or innovative applications tracks, a two-page extended abstract about the system must be submitted for review by the general paper submission deadline of 18 April 2024. For those demonstrations that are connected to a paper in one of the main conference tracks, no separate abstract about the demonstration should be submitted. The submission site, format and dates for extended abstracts are the same as for regular papers. Accepted extended abstracts will be published in the conference proceedings.

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 (
