INTRODUCTION
Many Asian countries are rapidly growing these days and the importance of communicating and exchanging the information with these countries has intensified.
To satisfy the demand for communication among these countries, machine translation technology is essential.
Machine translation technology has rapidly evolved recently and it is seeing practical use especially between European languages.
However, the translation quality of Asian languages is not that high compared to that of European languages,
and machine translation technology for these languages has not reached a stage of proliferation yet.
This is not only due to the lack of the language resources for Asian languages
but also due to the lack of techniques to correctly transfer the meaning of sentences from/to Asian languages.
Consequently, a place for gathering and sharing the resources and knowledge about Asian language translation is necessary to enhance machine translation research for Asian languages.
The Workshop on Machine Translation (WMT), the world's largest machine translation workshop, mainly targets on European languages and does not include Asian languages.
The International Workshop on Spoken Language Translation (IWSLT) has spoken language translation tasks for some Asian languages using TED talk data,
but these is no task for written language.
The Workshop on Asian Translation (WAT) is an open machine translation evaluation campaign focusing on Asian languages.
WAT gathers and shares the resources and knowledge of Asian language translation to understand the problems to be solved
for the practical use of machine translation technologies among all Asian countries.
WAT is unique in that it is an "open innovation platform":
the test data is fixed and open, so participants can repeat evaluations on the same data and confirm changes in translation accuracy over time.
WAT has no deadline for the automatic translation quality evaluation (continuous evaluation), so participants can submit translation results at any time.
In addition to the shared tasks, the workshop will also feature scientific papers on topics related to the machine translation, especially for Asian languages.
Topics of interest include, but are not limited to:
- analysis of the automatic/human evaluation results in the past WAT workshops
- word-/phrase-/syntax-/semantics-/rule-based, neural and hybrid machine translation
- Asian language processing
- incorporating linguistic information into machine translation
- decoding algorithms
- system combination
- error analysis
- manual and automatic machine translation evaluation
- machine translation applications
- quality estimation
- domain adaptation
- machine translation for low resource languages
- language resources

POLICY
Shared task participation policy:
- There is no limitation on the number of teams from one laboratory to apply for WAT2026.
- From one laboratory (not one team), at most two submissions are allowed for human evaluation in each sub-task.
- If a team takes part in human evaluation, it is mandatory to submit its system description paper and to attend the workshop.
- A team can submit its system description paper even only taking part in automatic evaluation.
- In the case that a team taking part in human evaluation but does not submit their system description paper,
the evaluation results, including automatic and by human, will not be presented in the overview paper provided by the organizers.
Research paper and system description paper submission policy:
- All the submissions to WAT2026 must follow the policy of AACL-IJCNLP 2026, excluding the following exceptions.
- Multiple Submission Policy: submitted papers must not be submitted elsewhere during the AACL-IJCNLP 2026 review period. This policy covers all refereed and archival conferences and workshops (e.g., IJCAI, SIGIR, NAACL). We make an exception to the above: papers can be dual-submitted to both AACL-IJCNLP 2026 and an AACL-IJCNLP 2026 workshop which has its submission deadline falling before our notification date of October 1, 2026.
In addition, we will not consider any paper that overlaps significantly in content or results with papers that will be (or have been) published elsewhere. Authors submitting more than one paper to AACL-IJCNLP 2026 must ensure that submissions do not overlap significantly (>25%) with each other in content or results.
- System description paper submission is only for the participants of shared tasks.
SHARED TASKS

RESEARCH PAPER
WAT2026 invites researchers to submit their original work on machine translation for Asian
languages. The scope covers studies and reports on theories, techniques, and resources to
improve the machines translation of Asian languages. All submitted research papers will be
examined under a double-blind peer-reviewing to decide if they will appear at the workshop.
Topics of interest include, but are not limited to:
- Word-/phrase-/syntax-/semantics-/rule-based, neural, and hybrids machine translation
- Asian language processing
- Incorporating linguistic information into machine translation
- Decoding algorithms
- System combination
- Error analysis
- Manual and automatic machine translation evaluation
- Machine translation applications
- Quality estimation
- Domain adaptation
- Machine translation for low resource languages
- Language resources
Format and Template:
Participants must use the same format as AACL-IJCNLP 2026 papers and follow the same instructions
in terms of the format. We do not distinguish between long and short papers.
Submission site:
All the papers must be submitted to our OpenReview Site.
For the ARR commitment submissions, please use this link.
SYSTEM DESCRIPTION PAPER
Participants who submit results for human evaluation are required to submit description
papers of their translation systems and evaluation results.
The format of system description paper is identical to that of research paper, but there is one difference: the system description paper is single-blind.
We do NOT review the paper, but just give feedback to improve the submitted system description papers.
