NOTE: This file implements translation tasks using datasets from WMT conferences, |
|
|
provided by sacrebleu. Traditionally they are evaluated with BLEU scores. TER |
|
|
and CHRF are other options. |
|
|
We defer citations and descriptions of the many translations tasks used |
|
|
here to the SacreBLEU repo from which we've obtained the datasets: |
