# Model Card for mT5-counternarrative-en

This is a fine-tuned text-to-text [mT5-base](https://huggingface.co/google/mt5-base) model to generate counternarratives against hate speech. 
The model has been fine-tuned on the [CONAN-EUS](https://huggingface.co/datasets/HiTZ/CONAN-EUS) splits of the
original CONAN dataset.

The CONAN (COunter NArratives through Nichesourcing) dataset was published by [Chung et al., 2019](https://aclanthology.org/P19-1271.pdf)
and is publicly available in [https://github.com/marcoguerini/CONAN](https://github.com/marcoguerini/CONAN).

CONAN-EUS was created by professionally translating all 6654 English HS-CN pairs of the original CONAN dataset into
**Basque and Spanish**. For experimentation we generated train, validation and test splits in a way that no HS-CN pairs occurred across them.

## HS-CN example

The CONAN dataset includes HS-CN pairs, regarding the topic of Muslims and Islam. 
An example of a HS-CN pair in Basque, Spanish and English is illustrated below: 

| HS                                                                                                                                                    | CN                                                                                                                      |
