NER-PT-BERT-CRF-Conll2003

Portuguese NER BERT-CRF Conll 2003

This model is a fine-tuned BERT model adapted for Named Entity Recognition (NER) tasks. It utilizes Conditional Random Fields (CRF) as the decoder.

The model follows the Conll 2003 labeling scheme for NER. Additionally, it provides options for HAREM Default and Selective labeling schemes.

How to Use

You can employ this model using the Transformers library's pipeline for NER, or incorporate it as a conventional Transformer in the HuggingFace ecosystem.

from transformers import pipeline
import torch
import nltk

ner_classifier = pipeline(
    "ner",
    model="arubenruben/NER-PT-BERT-CRF-Conll2003",
    device=torch.device("cuda:0") if torch.cuda.is_available() else torch.device("cpu"),
    trust_remote_code=True
)

text = "FCPorto vence o Benfica por 5-0 no Estádio do Dragão"
tokens = nltk.wordpunct_tokenize(text)
result = ner_classifier(tokens)
