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