Model Name: NER-finetuned-BETO

This is a BERT model fine-tuned for Named Entity Recognition (NER).

Model Description

This is a fine-tuned BERT model for Named Entity Recognition (NER) task using CONLL2002 dataset.

In the first part, the dataset must be pre-processed in order to give it to the model. This is done using the 🤗 Transformers and BERT tokenizers. Once this is done, finetuning is applied from BETO and using the 🤗 AutoModelForTokenClassification.

Finally, the model is trained obtaining the neccesary metrics for evaluating its performance (Precision, Recall, F1 and Accuracy)
