# cardiffnlp/twitter-xlm-roberta-base-hate-spanish

This model is a fine-tuned version of [cardiffnlp/twitter-xlm-roberta-base](https://huggingface.co./cardiffnlp/twitter-xlm-roberta-base) using the [`HaterNet`](https://zenodo.org/record/2592149) dataset and the Spanish subset of 
[`SemEval-2019 Task 5`](https://aclanthology.org/S19-2007/).

## Following metrics are achieved 

* `on the test split of SemEval-2019 Task 5`

  - F1 (weighted):  0.7866 
  - F1 (macro):  0.7935 
  - Accuracy:  0.7937

* on custom test split of `Haternet`

  - F1 (weighted): 0.7815
