LoResMT 2021 Shared Tasks
Registration open:
System submission due: July 01, 2021
(1) Taiwanese Sign Language () Traditional Chinese
(2) English () Irish
(3) English () Marathi


Based on the success of past low-resource machine translation (MT) workshops at AACL-IJCNLP 2020 (, MT Summit 2019 ( and AMTA 2018 (, we introduce the fourth LoResMT workshop at MT Summit 2021. Like its predecessors, this workshop will bring together researchers and translators of low-resource languages to compare and contrast how each uses digital technology for translation. Specifically, the workshop focuses on novel advances on the coverage of even more languages than past workshops with different geographical presence, degree of diffusion, and digitalization.

We solicit original work on low-resource translation which includes, but is not limited to, MT systems that include word tokenizers/de-tokenizers, word segmenters, morphological analyzers, and more. We furthermore invite work that includes MT systems based on neural networks along with their methods, natural language processing approaches, and overall coverage of low-resource languages. Additionally, novel work covering translations of COVID-related text and their practical use for low-resource communities is of high interest.

The goal of this workshop is to begin to close the gap between low-resource translation systems and their practical use in the real world. Online systems and original research that can be used by native speakers of low-resource languages is of particular interest. Therefore, It will be beneficial if the evaluations of these tools in research papers include their impact on the quality of MT output and how they can be used in the real world.


We are highly interested in (1) original research papers, (2) review/opinion papers, and (3) online systems on the topics below; however, we welcome all novel ideas that cover research on low-resource languages.
- COVID-related corpora, their translations and corresponding NLP/MT systems
- Neural machine translation for low-resource languages
- Work that presents online systems for practical use by native speakers
- Word tokenizers/de-tokenizers for specific languages
- Word/morpheme segmenters for specific languages
- Alignment/Re-ordering tools for specific language pairs
- Use of morphology analyzers and/or morpheme segmenters in MT
- Multilingual/cross-lingual NLP tools for MT
- Corpora creation and curation technologies for low-resource languages
- Review of available parallel corpora for low-resource languages
- Research and review papers of MT methods for low-resource languages
- MT systems/methods (e.g. rule-based, SMT, NMT) for low-resource languages
- Pivot MT for low-resource languages
- Zero-shot MT for low-resource languages
- Fast building of MT systems for low-resource languages
- Re-usability of existing MT systems for low-resource languages
- Machine translation for language preservation


We are soliciting two types of submissions. For research, review, and position papers, the length of each paper should be at least four (4) and not exceed eight (8) pages, plus unlimited pages for references. For system demonstration papers, the limit is four (4) pages. Submissions should be formatted according to the official MT Summit 2021 style templates (PDF, LaTeX, Word). Accepted papers will be published online in the MT Summit 2021 proceedings and will be presented at the conference either orally or as a poster.

Submissions must be anonymized and should be done using the official conference management system ( Scientific papers that have been or will be submitted to other venues must be declared as such, and must be withdrawn from the other venues if accepted and published at LoResMT. The review will be double-blind.

We would like to encourage authors to cite papers written in ANY language that are related to the topics, as long as both original bibliographic items and their corresponding English translations are provided.

Registration will be handled by the main conference. (To be announced)


March 25, 2021 – Call for papers released
May 04, 2021 – Second call for papers
May 20, 2021 – Third call for papers
July 1, 2021 – Paper submissions due [Submission Deadline Extended]
July 8, 2021 – Notification of acceptance
July 15, 2021 – Camera-ready due
August 5, 2021 – Video recordings due
August 16, 2021 - LoResMT workshop


We are happy to announce the introduction of new shared tasks focused on the building of MT systems for COVID-related texts. The task aims to encourage research on MT systems involving three low-resource language pairs:

(1) Taiwanese Sign Language () Traditional Chinese () 100,000 pairs)
(2) English () Irish
(3) English () Marathi

The training, development, and test sets for the three groups will be released shortly (please see the important dates). Updated information will be available on the LoResMT website ( and in the Google Group (
