cESA annotation protocol speeds up MT evaluation and is adopted by WMT26

zouharvi · x · 2026-09-14

The author shares an EMNLP paper introducing the cESA annotation protocol: annotators view multiple model outputs side by side, marking error spans and giving absolute scores, which is faster and more objective than judging one output at a time. It is implemented in the open-source tool Pearmut and used in the WMT26 evaluation.
