AlbertoC/roberta-negative-emotions

This model is based on the Spanish version of ROBERTA, specifically ClassCat/roberta-base-spanish, and has been fine-tuned to classify negative emotions in Spanish tweets.

The fine-tuning was performed using a labeled corpus available from the IPN CIC repository https://www.cic.ipn.mx/~sidorov/corpus_marcado6emociones.txt, which contains Spanish tweets annotated with six emotions.

For this model, only the four negative emotions defined by Ekman were used:

0 → Anger

1 → Disgust

2 → Fear

3 → Sadness

The model is designed to support tasks in emotion detection and sentiment analysis in Spanish.
