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.

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:

Call for Papers

Authors are invited to submit by August 8th original and unpublished research papers in the following categories: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 22nd 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.
