ssa-comet-stl

SSA-COMET-STL, a robust, automatic metric for MTE, built based on SSA-MTE: It receives a triplet with (source sentence, translation, reference translation), and returns a score that reflects the quality of the translation. This model is based on an improved African enhanced encoder, afro-xlmr-large-76L.

Usage (SSA-COMET)

Using this model requires unbabel-comet to be installed:

pip install --upgrade pip  # ensures that pip is current 
pip install unbabel-comet

Then you can use it through comet CLI:

comet-score -s {source-inputs}.txt -t {translation-outputs}.txt -r {references}.txt --model McGill-NLP/ssa-comet-stl

Or using Python:

from comet import download_model, load_from_checkpoint
model_path = download_model("McGill-NLP/ssa-comet-stl")
model = load_from_checkpoint(model_path)
data = [
    {
        "src": "Nadal sàkọọ́lẹ̀ ìforígbárí o ní àmì méje sóódo pẹ̀lú ilẹ̀ Canada.",
        "mt": "Nadal's head to head record against the Canadian is 7–2.",
        "ref": "Nadal scored seven unanswered points against Canada."
    },
    {
        "src": "Laipe yi o padanu si Raoniki ni ere Sisi Brisbeni.",
        "mt": "He recently lost against Raonic in the Brisbane Open.",
        "ref": "He recently lost to Raoniki in the game Sisi Brisbeni."
    }
]
model_output = model.predict(data, batch_size=8, gpus=1)
print (model_output)

Intended uses

Our model is intended to be used for MT evaluation.

Given a triplet with (source sentence, translation, reference translation), it outputs a single score between 0 and 1, where 1 represents a perfect translation.
