# Hate Speech detection in Spanish
## robertuito-hate-speech
Repository: [https://github.com/pysentimiento/pysentimiento/](https://github.com/finiteautomata/pysentimiento/)
Model trained with SemEval 2019 Task 5: HatEval (SubTask B) corpus for Hate Speech detection in Spanish. Base model is [RoBERTuito](https://github.com/pysentimiento/robertuito), a RoBERTa model trained in Spanish tweets.
It is a multi-classifier model, with the following classes:
- **HS**: is it hate speech?
- **TR**: is it targeted to a specific individual?
- **AG**: is it aggressive?
## Results
Results for the four tasks evaluated in `pysentimiento`. Results are expressed as Macro F1 scores
