Call for Shared Task Proposals: ArgMining 2026
by Musi, Elena 16 Dec '25

16 Dec '25

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)

Our offices will reopen on Monday, January 5, 2026. Requests received by the Membership Office during Winter Break will be processed when the office reopens. ________________________________ New publications: 2021 NIST Speaker Recognition Evaluation Test Set<https://catalog.ldc.upenn.edu/LDC2025S11> was developed by LDC and NIST (National Institute of Standards and Technology). It contains approximately 447 hours of Cantonese, Mandarin, and English conversational telephone speech, audio from video, and selfie image data for development and test, along with answer keys, enrollment, trial files, and documentation from the NIST-sponsored 2021 Speaker Recognition Evaluation (SRE)<https://www.nist.gov/itl/iad/mig/nist-2021-speaker-recognition-evaluation-s…>. The SRE task is speaker detection, that is, to determine whether a specified target speaker was speaking during a segment of speech. SRE21 focused on telephone speech and audio from video and included close-up images of participants. The evaluation also featured cross-lingual trials, that is, enrollment and test segments spoken in different languages. The data was drawn from the WeCanTalk corpus collected by LDC in which speakers called friends or relatives who agreed to record their telephone conversations lasting between 8-10 minutes. Subjects contributed multiple conversational telephone speech recordings and audio recordings in which they were talking, plus a single selfie image. Recordings were manually audited to verify speaker, language, and quality. 2025 members can access this corpus through their LDC accounts. Non-members may license this data for a fee. * LORELEI Sinhala Incident Language Pack<https://catalog.ldc.upenn.edu/LDC2025T17> was developed by LDC and is comprised of 8.1 million words of Sinhala monolingual text, 700,00 words of English monolingual text, 6.4 million words of parallel Sinhala- English text, and 50,000 words annotated for entity discovery and linking and situation frames. It constitutes all of the text data, annotations, supplemental resources, and related software tools for the Sinhala language used in the DARPA LORELEI / LoReHLT 2018 Evaluation<https://www.nist.gov/itl/iad/mig/lorehlt-evaluations>. The LORELEI (Low Resource Languages for Emergent Incidents) program was concerned with building human language technology for low resource languages in the context of emergent situations. In the evaluation scenario, an unforeseen event triggered a need for humanitarian and logistical support in a region where the incident language had received little or no attention in NLP research. Evaluation participants provided NLP solutions, including information extraction and machine translation, with limited resources and limited development time. Data was collected from news, social network, weblog, newsgroup, discussion forum, and reference material. Entity discovery and linking annotation identified entities to be detected by systems for scoring purposes. Situation frame analysis was designed to extract basic information about needs and relevant issues for planning a disaster response effort. 2025 members can access this corpus through their LDC accounts.
