response-toxicity-classifier-base
BERT classifier from Skoltech, finetuned on contextual data with 4 labels.
Training
Skoltech/russian-inappropriate-messages was finetuned on a multiclass data with four classes (check the exact mapping between idx and label in model.config).
- OK label — the message is OK in context and does not intent to offend or somehow harm the reputation of a speaker.
- Toxic label — the message might be seen as a offensive one in given context.
- Severe toxic label — the message is offencive, full of anger and was written to provoke a fight or any other discomfort
- Risks label — the message touches on sensitive topics and can harm the reputation of the speaker (i.e. religion, politics)
The model was finetuned on a soon-to-be-posted dialogs datasets.
Evaluation results
Model achieves the following results on the validation datasets (will be posted soon):
| OK - F1-score | TOXIC - F1-score | SEVERE TOXIC - F1-score | RISKS - F1-score | |
|---|---|---|---|---|
| internet dialogs | 0.896 | 0.348 | 0.490 | 0.591 |
| chatbot dialogs | 0.940 | 0.295 | 0.729 | 0.46 |
