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 summaries of proposals for animal experiments. This year, the biomedical translation task will address the following language pairs:

• English-Chinese and Chinese-English (en/zh, zh/en)
• English-French and French-English (en/fr, fr/en)
• English-German and German-English (en/de, de/en)
• English-Italian and Italian-English (en/it, it/en)
• English-Portuguese and Portuguese-English (en/pt, pt/en)
• English-Russian and Russian-English (en/ru, ru/en)
• English-Spanish and Spanish-English (en/es, es/en)

Data

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 considererd in the evaluation.

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

• The Biomedical Translation repository includes links to parallel corpora of scientific publications (en/pt, en/es, en/fr, en/de, en/zh, en/it, en/ru), among others
• The UFAL Medical Corpus (formerly HimLCorpus) includes medical text from various sources for many language pairs (en/es, en/de, en/fr, en/ro) HimL test sets can be used as the development sets for some language pairs (en/es, en/de, en/fr, en/ro)
• The Khresmoi development data can be used for some language pairs (en/es, en/de, en/fr).
• The UNCorpus contains training data for some languages (en/es, en/fr, en/zh)
• The MeSpEn corpus contains many parallel documents of en/es
• The Scielo full text corpus for en, es and pt
• The Brazilian Thesis and Dissertations for en/pt

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

• Russian/English (both directions)
• Spanish/English (both directions)
• Clinical case reports:
• English into Spanish
• Ontology Concepts:

Test Sets and Submission formats

Scientific abstracts:

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

DOC_ID	SENT_ID	SENTENCE_TEXT

• DOC_ID: sequential one, e.g. doc1, doc8, not the original PMID in Medline
• SENT_ID: a sequential number from 1 to n
• SENTENCE_TEXT: the sentence text to be translated by the participants

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
...

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.

For all participants, before 4th August: Prepare an abstract of your system (it may be a half/one-page brief description, or already full system description paper) and upload it to the paper submission system. Only primary systems of teams that submit an abstract paper will be included in the human evaluation.

It is possible to download test sets and submit the translation either using OCELoT or our submission system. Our testsets are also included in the General MT Task. Please check instructions below.

OCELoT

1. Register your team at OCELoT.
2. Send an email with your name, affiliation, OCELoT username to wmtbiomedical@gmail.com to get your team activated (it is not possible to submit translations before team validation).
3. Download testsets for the Biomedical task and sub-tasks.
4. You may want to use XML wrapping and unwrapping scripts.
5. Translate testsets.
6. Upload your submissions to the OCELoT. Each team is allowed at most 3 submissions per language pair. Scores in the system do not reflect actual system performance, they are mainly for validation purposes.

WMT Biomedical Submission System

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'22 biomedical task Google Drive folder. For the test sets for the "Clinical case reports", "Ontology Concepts", and "Clinical Terminology" sub-tasks, please refere to OCELoT above.

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:

• The submission file for run 1 of the "ABC" team for the Medline scientific abstracts from English into Spanish should be called "ABC_run1_medline_en2es_es.txt".
• The submission file for run 3 of the "ABC" team for the Medline scientific abstracts from Spanish into English should be called "ABC_run3_medline_es2en_en.txt".

Each team will be allowed to submit up to 3 runs per test set.
