We invite submissions of shared task proposals for ArgMining 2026, the 13th Workshop on Argument Mining and Reasoning, co-located with ACL 2026 (San Diego).
Background Argument mining (also known as argumentation mining) is a well-established area in computational linguistics focusing on the automatic identification of argumentative structures such as premises, conclusions, and inference schemes. The field has historically emphasized the development of large-scale datasets and tasks including argument quality assessment, argument persuasiveness, and argumentative text synthesis across domains such as legal, social, medical, political, and scientific settings. In line with broader advances in CL and NLP, recent work has expanded toward explainable argumentation, multimodal settings, and modeling human label variation. Previous editions of ArgMining have promoted shared tasks to advance research on specific aspects of argument mining, including: * Multimodal argumentative fallacy detection: https://nlp-unibo.github.io/mm-argfallacy/2025/ Dialogical argument mining: http://dialam.arg.tech/ ArgMining 2026 Shared Tasks Following the success of prior workshops, ArgMining 2026 plans to feature one or more shared tasks addressing unsolved problems for the community to investigate. In keeping with this year’s special theme—“Understanding and evaluating arguments in both human and machine reasoning”—we particularly encourage proposals aligned with this focus. What to Include in a Proposal Shared task proposals should include: * Title and brief task description * Description of the datasets to be used and their readiness * Previous work on the datasets, including relevant publications (if any) * A short description of the evaluation methodology for submitted systems * Brief introduction of the task organizers * Anticipated timeline, including dates for dataset releases and final evaluation How to Submit Submit your shared task proposal via email to: argmining.org [at] gmail.com * Submission deadline: December 22, 2025 * Notification of acceptance: beginning/mid January 2026 Tentative Shared Task Schedule * Mid January: Training data release * Early March: Test data release; evaluation start * Mid/late March: Evaluation end * Early April: Results announcement * Mid April: Paper submission deadline * Mid May: Camera-ready deadline * July: ArgMining 2026 workshop (at ACL) Organizers Mohamed Elaraby (University of Pittsburgh) Annette Hautli-Janisz (University of Passau) John Lawrence (University of Dundee) Elena Musi (University of Liverpool) Julia Romberg (GESIS) Federico Ruggeri (University of Bologna)
