This conference builds on a series of annual workshops and conferences on statistical machine translation, going back to 2006:


Release of training data for shared tasksFebruary/March, 2021
Evaluation periods for shared tasksJune/July, 2021
Paper submission deadlineAugust 5, 2021 (Anywhere on Earth)
Paper notificationSeptember 5, 2021
Camera-ready version dueSeptember 15, 2021
Conference in Punta CanaNovember 10-11 , 2021


This year's conference will feature the following shared tasks:

In addition to the shared tasks, the conference will also feature scientific papers on topics related to MT. Topics of interest include, but are not limited to:

We encourage authors to evaluate their approaches to the above topics using the common data sets created for the shared tasks.


These will both be handled by EMNLP 2021.


WMT has a number of MT-related shared tasks. Please consult the links at the top of the page for more details.


WMT accepts two types of submissions: research papers and system papers. Both types of papers are submitted electronically, have the same deadlines, and should follow EMNLP2021 formatting guidelines. WMT will participate in the ACL Rolling Review and any paper submitted to ARR by July 15th can be considered for publication in WMT.

Research Papers

Research papers should describe original research corresponding to the categories listed above. Research papers that have been or will be submitted to other meetings or publications must indicate this at submission time, and must be withdrawn from the other venues if accepted and published at WMT 2021. We will not accept for publication papers that overlap significantly in content or results with papers that have been or will be published elsewhere. It is acceptable to submit work that has been made available as a technical report (or similar, e.g. in arXiv) without citing it. For the research track, papers should be anonymised, be between 6 and 10 pages in length (excluding references) and may include supplementary material.

We encourage individuals who are submitting research papers to evaluate their approaches using the training resources provided by this conference and past workshops, so that their experiments can be repeated by others using these publicly available corpora.

System Papers

System papers must describe one or more shared task submissions. System paper submissions that we cannot link to a shared task submission will be rejected without review. System papers can overlap with other published work, and do not have to follow the double submission policy. There is no maximum length for system papers, but normally a short paper (4-6 pages) is appropriate. System papers should not be anonymised.


Details TBC, but we expect that posters will be presented in Gather.Town.
