cometoid22-wmt22

cometoid22-wmt22

A referenceless/quality-estimation metric for machine translation evaluation. This metric is created by using the knowledge distillation of wmt22-comet-da (a referece-based teacher). Refer to the publication for technical details.

Setup

Option 1: Install pymarian, aka python bindings to marian

pip install pymarian

Option 2: Build marian binary, reference: https://marian-nmt.github.io/quickstart/

Usage

Pymarian

pymarian-eval -m checkpoints/marian.model.bin -v vocab.spm --like comet-qe  -s src.txt -t mt.out.txt

Marian

paste src.txt mt.out.txt | marian evaluate --quiet --model checkpoints/marian.model.bin --vocabs vocab.spm vocab.spm --width 4 --like comet-qe \
  --mini-batch 16 --maxi-batch 256 --max-length 512 --max-length-crop true --workspace 8000
