# Model Name: bert-finetuned-ner-1

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 *[bert-base-cased](https://huggingface.co/google-bert/bert-base-cased)* and using the 🤗 *AutoModelForTokenClassification*.

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