WMT24++ Reference Translations for Romansh

Description

WMT24++ benchmark in Romansh (six varieties: Rumantsch Grischun, Sursilvan, Sutsilvan, Surmiran, Puter, and Vallader).

Paper: "Expanding the WMT24++ Benchmark with Rumantsch Grischun, Sursilvan, Sutsilvan, Surmiran, Puter, and Vallader"
Code: https://github.com/ZurichNLP/romansh_mt_eval
Original WMT24++ benchmark (55 languages): https://huggingface.co/datasets/google/wmt24pp
The reference translation have been created by human translators based on the German version of WMT24++.

The Sutsilvan subset is currently incomplete. See Appendix A of the paper for an overview. We will update the dataset once the Sutsilvan translations have been completed.

Data Creation Workflow

The data acquisition process was structured into three steps to ensure high quality, consistency, and adherence to idiom-specific conventions.

Translation: We hired language professionals who are native speakers of both German and the respective Romansh idiom.
Review: Two expert linguists of Lia Rumantscha reviewed a sample of translations for a representative selection of varieties, and formulated feedback that was communicated to all translators.
Revision: The translators incorporated the feedback into the reference translations.

We provided the translators with a guidelines document, inspired by the WMT24 translator brief.

The key points of the guidelines, which we provide in Appendix E of the paper, are:

The German text is the main source for the translation into Romansh, while the English text can be used as an additional reference in case of ambiguity.
No AI tools should be used for the translation.

The translators and reviewers had access to the complete context of each segment, including a link to the original website from which the segment was extracted (e.g., for segments from the Speech domain, the original YouTube video).
