The 9th Workshop on Event Extraction and Understanding: Challenges and Applications (EEUCA 2026) (formerly CASE) @ ACL 2026
Also, this year the EEUCA workshop continues the tradition of the eight previous editions of our workshop on challenges and applications of event extraction. Website: https://bit.ly/EEUCA2026 Submission page: https://openreview.net/group?id=aclweb.org/ACL/2026/Workshop/EEUCA Paper submission deadline: March 16, 2026 Pre-reviewed ARR commitment deadline: April 15, 2026 Notification of acceptance: April 28, 2026 Camera-ready paper due: May 12, 2026 Pre-recorded video due (hard deadline): June 4, 2026 Shared tasks and shared task papers: Start of the Competition: Dec 10, 2025 Eval Phase Start: Dec 10, 2025 Test Phase Start: Jan 15, 2026 Test Phase End: March 15, 2026 Paper Submission Deadline: March 28, 2026 Notification of acceptance: April 28, 2026 Camera-ready paper due: May 12, 2026 We invite work on all aspects of automated coding and analysis of events from mono- or multi-lingual text sources. This includes (but is not limited to) the following topics 1) Extracting events and their arguments in and beyond a sentence or document, event coreference resolution. 2) New datasets, training data collection and annotation for event information. 3) Event-event relations, e.g., subevents, main events, spatiotemporal relations, causal relations. 4) Event dataset evaluation in light of reliability and validity metrics. 5) Defining, populating, and facilitating event schemas and ontologies. 6) Automated tools and pipelines for event collection related tasks. 7) Lexical, syntactic, semantic, discursive, and pragmatic aspects of event manifestation. 8) Methodologies for development, evaluation, and analysis of event datasets. 9) Applications of event databases, e.g. early warning, conflict prediction, and policymaking. 10) Estimating what is missing in event datasets using internal and external information. 11) Detection of new event types, e.g. creative protests, cyber activism, COVID-19 related, terrorism, food safety, food security, climate change, extreme weather events, disasters. 12) Release of new event datasets, 13) Bias and fairness of the sources and event datasets. 14) Ethics, misinformation, privacy, and fairness concerns pertaining to event datasets. 15) Copyright issues on event dataset creation, dissemination, and sharing. 16) Cross-lingual, multilingual, and multimodal aspects in event analysis. 17) Exploiting LLMs in Event Extraction. 18) Generative AI and event reports: detecting AI-generated news, exploiting generative AI for creating event corpora, etc. Shared Task 1: Multimodal Identification of Vaccine Critical Content on Social Media This shared task focuses on detecting vaccine-critical stance in multimodal social media memes. Using the VaxMeme dataset of over 10,000 annotated memes, participants will develop models that jointly leverage visual and textual signals to classify a meme’s stance as pro-vaccine, vaccine-critical, or neutral. The task encourages research on cross-modal understanding, sarcasm, implicit messaging, and misinformation dynamics in public health discourse. External data and transfer learning are permitted, and submissions will be evaluated using macro-F1. All system description papers will be published in the ACL Anthology.

Participants will develop models that classify a player’s message into six fine-grained intent categories, including hate, threats, insults, extremism, and non-toxic communication. The challenge highlights contextual nuance, gaming slang, implicit aggression, and varied severity levels of toxicity. External datasets are allowed, and submissions are evaluated using macro-F1. All system description papers will be published in the ACL Anthology.
