Task Description


In this shared task, your goal is to correct a text in the Ukrainian language to make it grammatical or both grammatical and fluent. We see this shared task as an opportunity to facilitate research of GEC for Slavic languages.


There are two tracks in this shared task: GEC-only and GEC+Fluency. It is not mandatory to participate in both subtasks, i.e., participating in either GEC-only or GEC+Fluency is acceptable.


You can find the detailed instructions, train and validation data, and the evaluation script at




Teams that intend to participate should register by filling in this form.




Participants in the shared task are invited to submit a paper to the UNLP 2023 workshop. Submitting a paper is not mandatory for participating in the Shared Task. Papers must follow the workshop submission instructions and will undergo regular peer review. Their acceptance will not depend on the results obtained in the shared task, but on the quality of the paper. Accepted papers will appear in the ACL anthology and will be presented at a session of UNLP 2023 specially dedicated to the Shared Task.
