Multilingual Verdict Classifier

This model is a fine-tuned version of xlm-roberta-base on 2,500 deduplicated multilingual verdicts from Google Fact Check Tools API, translated into 65 languages with the Google Cloud Translation API. It achieves the following results on the evaluation set, being 1,000 such verdicts, but here including duplicates to represent the true distribution:

—Loss: 0.2238
—F1 Macro: 0.8540
—F1 Misinformation: 0.9798
—F1 Factual: 0.9889
—F1 Other: 0.5934
—Prec Macro: 0.8348
—Prec Misinformation: 0.9860
—Prec Factual: 0.9889
—Prec Other: 0.5294
