Shared Task: Biomedical Translation Task

Task description

This task aims to evaluate systems on the translation of documents from the biomedical domain. The test data will consist of biomedical abstracts and it will address the following language pairs:


ATTENTION!! We ask the participants to not download the Medline database by themselves in order to retrieve training data. Submissions that are derived from a model that was trained on the whole PubMed will be not considered in the evaluation.

Participants can rely on training (and development) data from various sources, for instance:

Participants are also free to use out-of-domain data.


Evaluation will be carried out both automatically and manually. Automatic evaluation will make use of standard machine translation metrics, such as BLEU.

Native speakers of each of the languages will manually check the quality of the translation for a small sample of the submissions. If necessary, we also expect participants to support us in the manual evaluation (accordingly to the number of submissions).

We plan to release test sets for the following language pairs and sources:

Scientific abstracts:

For the test set of Medline abstracts, the format will be plain text files. The format will be the following:

The three values are separated by a TAB character:
doc1	1	sentence_1
doc2	2	sentence_2
doc2	3	sentence_3
doc2	4	sentence_4
doc2	5	sentence_5
doc2	n	sentence_n
doc4	1	sentence_1
doc4	2	sentence_2
The format for the submission will be the same, such as in the example below. The participants should follow the same order of the sentences as in the original test set file.
doc1	1	translated_sentence_1
doc2	2	translated_sentence_2
doc2	3	translated_sentence_3
doc2	4	translated_sentence_4
doc2	5	translated_sentence_5
doc2	n	translated_sentence_n
doc4	1	translated_sentence_1
doc4	2	translated_sentence_2

Submission Requirements

Please notice that, following general WMT policy explicitly enforced in other tasks, we will release all participants' submissions after this year's edition of the task to promote further studies.

Please register your team using this form. You will receive a mail with the confirmation of your registration. The link for submission site will be informed in this mail. Please register your team as soon as possible.

The Medline test files are available in the WMT'23 biomedical task Google Drive folder.

The format for the submission files should include the original test file name preceded by the team identifier (as registered in the form above) and the run number, following this example for the abstracts:

Each team will be allowed to submit up to 3 runs per test set. Please notice that the submission form will include questions about details of your methods, please inform as much details as possible, this is important for us.


Initial results for the biomedical task are available here.
