Multilingual Hate Speech Classifier for Social Media Content
A multilingual model for hate speech classification of social media content. The model is based on pre-trained multilingual representations from the XLM-T model (https://arxiv.org/abs/2104.12250) and was jointly fine-tuned on five languages, namely Arabic, Croatian, English, German and Slovenian. The test results on these five languages in terms of F1 score are as follows:
| Language | F1 |
|---|---|
| Arabic | 0.8704 |
| Croatian | 0.7226 |
| English | 0.7851 |
| German | 0.7826 |
| Slovenian | 0.7596 |
Tokenizer
During training the text was preprocessed using the original XLM-T tokenizer. The pretrained tokenizer files are included in this repository. We suggest the same tokenizer is used for inference.
Model output
The model classifies each input into one of two distinct classes:
- 0 - not-offensive
- 1 - offensive
