+This model is based on the multilingual version of BERT, specifically google-bert/bert-base-multilingual-cased, 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.
