Welcome to the website of the second UncertaiNLP workshop to be held at EMNLP 2025 in Suzhou, China.

Tagline: UncertaiNLP brings together researchers embracing sources of uncertainty from human language and NLP tools; harnessing them for improved NLP.

Previous editions of UncertaiNLP: 2024.

Update 18/07: We have extended the submission deadlines and the subsequent review schedule by a week!

Important Dates

All deadlines are 11:59pm UTC-12 (“anywhere on earth”).

Workshop Topic and Content

Human languages are inherently ambiguous and understanding language input is subject to interpretation and complex contextual dependencies. Nevertheless, the main body of research in NLP is still based on the assumption that ambiguities and other types of underspecification can and have to be resolved. This workshop will provide a platform for research that embraces variability in human language and aims to represent and evaluate the uncertainty that arises from it, and from modeling tools themselves.

Workshop Topics

UncertaiNLP welcomes submissions to topics related (but not limited) to:

Invited Speakers

Gal Yona Clara Meister Eyke Hüllermeier
Gal Yona (Google Research, IL)
Maxim Panov (MBZUAI, UAE)
Eyke Hüllermeier (LMU Münich, DE)

Gal Yona is a Research Scientist at Google Research, Tel Aviv, where she is working on improving factuality in large language models, with an emphasis on robustness and uncertainty. Before joining Google, Gal completed her PhD in Computer Science at the Weizmann Institute of Science, developing definitions and algorithms for preventing discrimination in machine learning models. Gal received numerous award during her PhD, including the Google PhD Fellowship in Machine Learning (2021).

Maxim Panov is an Assistant Professor at MBZUAI, UAE. Before joining MBZUAI, Panov worked as a research scientist at DATADVANCE Company, where he participated in developing a library of data analysis methods for engineering applications. This library, pSeven, is now used by many companies worldwide, including Airbus, Porsche, Mitsubishi, Toyota, and Limagrain. From 2018, Panov has been an assistant professor at Skolkovo Institute of Science and Technology, Moscow, where he led a statistical machine learning group. Since 2022, he has led an AI theory and algorithms group at the Technology Innovation Institute, Abu Dhabi, UAE. His research interests lie in uncertainty quantification for machine learning model predictions and Bayesian approaches in machine learning. Maxim is leading a research team dedicated to exploring the theoretical foundations of uncertainty quantification and its practical applications. Maxim is also co-leading the development of the LM-Polygraph framework for uncertainty quantification for LLMs. Maxim was a local chair for the ICDM 2024 conference and a recipient of the Best Paper Runner-up Award at the Uncertainty in Artificial Intelligence 2023 conference.

Eyke Hüllermeier heads the Chair of Artificial Intelligence and Machine Learning at LMU Munich. His research interests are centered around methods and theoretical foundations of artificial intelligence, with a specific focus on machine learning and reasoning under uncertainty. He has published more than 300 articles on these topics in top-tier journals and major international conferences, and several of his contributions have been recognized with scientific awards.

Call for Papers

Authors are invited to submit by August 15th original and unpublished research papers in the following categories:

All submissions must be in PDF format, submitted electronically via OpenReview and should follow the EMNLP 2025 formatting guidelines (following the ARR CfP: use the official ACL style templates, which are available here).

We now accept submissions with already existing ACL Rolling Reviews (ARR) via OpenReview, with the deadline August 29th AoE. These submissions must have been reviewed by ARR before, which will be used in our evaluation, and which must be linked to our system through the paper link field available in the OpenReview form. Please make sure to also follow the EMNLP 2025 formatting guidelines (following the ARR CfP: use the official ACL style templates, which are available here).

All submissions are archival, but we also invite authors of papers accepted to Findings to reach out to the organizing committee of UncertaiNLP to present their papers at the workshop, if in line with the topics described above.

Camera-ready versions for accepted archival papers should be uploaded to the submission system by the camera-ready deadline. Authors may use up to one (1) additional page to address reviewer comments.

Call for Papers is available here.
