# Named Entity Recognition (NER) model for Portuguese |
|
|
|
This is a NER model for Portuguese which uses the standard 'enamex' classes: LOC (geographical locations); PER (people); ORG (organizations); MISC (other entities). |
|
|
|
The model is based on [BERTimbau Base](https://huggingface.co/neuralmind/bert-base-portuguese-cased), which has been fine-tuned using a combination of available corpora (see [1] for details). |
|
|
|
There is an alternative model trained using [BERTimbau Large](https://huggingface.co/neuralmind/bert-large-portuguese-cased): [bert-large-pt-ner-enamex](https://huggingface.co/marcosgg/bert-large-pt-ner-enamex). |
|
|
|
It was trained with a batch size of 8 and a learning rate of 2e-5 during 3 epochs. It achieved the following results on the test set (Precision/Recall/F1): 0.913/0.918/0.915. |
