EEUCA Workshop @ ACL 2026 (Formerly CASE)

Call for workshop papers and Shared Task participation: 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. 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.

EEUCA will be held in ACL 2026! I will be co-chairing this workshop alongside my friends @hurrial and @TechnoTwitBot Excited for this 9th edition of the workshop!

We are glad to share that the 9th CASE workshop will be held alongside ACL 2026 as the 9th Workshop on Event Extraction and Understanding: Challenges and Applications (EEUCA 2026)! Stay tuned for further updates. @hurrial @therealthapa @TechnoTwitBot

Last day to commit your pre-reviewed submissions to WiNLP 2025 @WiNLPWorkshop

🚨 Deadline Extended! 🚨 Submit your paper to the CASE Workshop at #RANLP2025! 🗓️ New Deadline: August 4, 2025 Don’t miss the chance to share your work on socio-political event extraction! 📢 #NLProc #CFP #CASE2025

Excited to chair @WiNLPWorkshop for next two years! Please submit to WiNLP which is co-located at EMNLP this year. More details in CFP link provided.

Chairs @hurrial @TechnoTwitBot @therealthapa

We are also hosting a shared task on multimodal detection of hate speech, humor, and stance in marginalized socio-political discourse. To know more and participate, please visit: lnkd.in/eBwrDgSr All shared task papers will also be published in ACL anthology.

• Legal, ethical, and privacy considerations in dataset creation and dissemination. • Cross-lingual, multilingual, and multimodal event extraction. • Use of LLMs and generative AI for event extraction, analysis, and dataset generation.

• Applications of event data in conflict prediction, early warning, and policy support. • Detection of emerging SPE types, including protests, public health crises, and cyber activism. • Bias, fairness, and misinformation in event extraction systems and datasets.

• Event schemas and ontologies: population, definition, and enrichment. • Tools, pipelines, and infrastructure for event annotation and analysis. • Linguistic aspects of event representation: lexical, syntactic, semantic, discursive, and pragmatic.

• Creation and annotation of datasets for event extraction. • Modeling event-event relations such as subevents, causal, temporal, and spatial links. • Evaluation of event datasets: reliability, validity, and coverage.

Call for Papers: CASE 2025 @ RANLP Challenges and Applications of Automated Extraction of Socio-political Events from Text (CASE)

We invite submissions of research papers, resource papers, and position papers addressing (but not limited to) the following topics: • Event extraction at the sentence, document, or cross-document level, including event coreference.

CASE is a leading venue for research, resources, and practical advances in automated event extraction and analysis, with a focus on social and political event data. It has been organized consistently in top venue like ACL, EMNLP, EACL, etc.

Submit paper at: lnkd.in/ekfTx2HN Submission Deadline: 6 July 2025 We are pleased to announce the 8th edition of the CASE workshop, to be held in conjunction with RANLP 2025!

Excited to host you all!
