Dear colleagues, We cordially invite submissions of shared tasks as part of ArgMining 2025, the “12th Workshop on Argument Mining”. The workshop will be co-located with ACL 2025 (to be held in Vienna, Austria). Argument mining (also known as “argumentation mining”) is a gradually maturing research area within computational linguistics. It involves the automatic identification of argumentative structures in free text, as well as argument quality assessment, argument persuasiveness, and the synthesis of argumentative texts. To advance research on specific aspects of argument mining, previous editions of the ArgMining workshop series have promoted shared tasks, including key point analysis for quantitative summarization of arguments (see Argmining 2021 ), the validity and novelty of arguments (see Argmining 2022), multimodal argument mining and pragmatic tagging of peer reviews (see Argmining 2023, and argument mining considering perspective and dialogical aspects (see Argmining 2024). Following the success of previous workshops, ArgMining 2025 plans to share one or more unsolved problems to be investigated by the community. Proposals for shared tasks should include: a title and a brief description of the task a description of the datasets that will be used in the task and their readiness, and a proposed plan for data collection and annotation previous work on the datasets, including publications (if any) a few lines regarding evaluation of the submitted systems a brief introduction of the task organizers Shared task organizers will have the opportunity to publish a task overview paper in the workshop proceedings. Please submit your shared task proposal via email to argmining.org<http://argmining.org/>2025 [at] gmail.com<http://gmail.com/>. The submission deadline is January 7th, 2025, and task organizers will be notified of proposal acceptance on January 19th. While exact dates are not yet available, we assume the following tentative schedule: End of February - Training data release Mid of April - Test data release, evaluation start End of April - Evaluation end Mid of May - Results announcement End of May - Paper submission due Mid of June - Camera-ready version due July 31st or August 1st 2025 - ArgMining 2025 workshop (ACL) The timeline will be finalized with the shared task organizers.
