Call for Papers: The 3rd Workshop on Uncertainty-Aware NLP @ EMNLP 2026
We are pleased to announce the Third Workshop on Uncertainty-Aware NLP (UncertaiNLP 2026), which will be held in conjunction with EMNLP 2026 in Budapest, Hungary, on October 29, 2026.
UncertaiNLP brings together researchers studying uncertainty in human language and NLP systems, including LLMs, and how uncertainty can be represented, estimated, evaluated, and harnessed to build more reliable NLP technologies.
We invite submissions on topics including uncertainty representation and quantification, calibration and conformal prediction, ambiguity and variation in language, hallucination detection, selective prediction, active learning, retrieval-augmented systems, multimodal systems, and related areas.
SUBMISSIONS
We welcome full papers of up to 8 pages and short papers of up to 4 pages. The workshop accepts:
- Archival submissions
- Non-archival submissions
- ARR commitments
INVITED SPEAKERS
We are excited to announce four distinguished invited speakers:
- Dan Roth, University of Pennsylvania and Oracle
- Yingzhen Li, Imperial College London
- André F. T. Martins, Instituto Superior Técnico / Instituto de Telecomunicações
- Gintare Karolina Dziugaite, Google DeepMind
SHROOM-VISIONS SHARED TASK
UncertaiNLP 2026 will also feature SHROOM-Visions, the fourth edition of the SHROOM shared task on hallucination detection.
This year’s shared task focuses on fine-grained hallucination span detection for Vision-and-Language Models. Participants will work on identifying hallucinated spans in model outputs across Chinese, English, French, and Italian, contributing to the development of more reliable and uncertainty-aware multimodal systems.
Further details about the shared task, including data, participation instructions, and evaluation setup, will be announced on the workshop website.
IMPORTANT DATES
- Submission deadline: August 7, 2026
- Workshop date: October 29, 2026
- Deadlines are 11:59pm UTC-12 / Anywhere on Earth
