Portuguese Name Identification

The NoHarm-Anony - De-Identification of Clinical Notes Using Contextualized Language Models and a Token Classifier paper contains ModernBert-based models for Portuguese Language, initialized with Ettin-17m & trained on clinical notes with names tagged.

Demo: How to use in Flair

Requires: Flair (pip install flair)

python

from flair.data import Sentence
from flair.models import SequenceTagger
# load tagger
tagger = SequenceTagger.load("noharm-ai/anony")
# make example sentence
sentence = Sentence("FISIOTERAPIA TRAUMATO - MANHÃ  Henrique Dias, 38 anos. Exercícios metabólicos de extremidades inferiores. Realizo mobilização patelar e leve mobilização de flexão de joelho conforme liberado pelo Dr Marcelo Arocha. Oriento cuidados e posicionamentos.")
# predict NER tags
tagger.predict(sentence)
# print sentence
print(sentence)
# print predicted NER spans
print('The following NER tags are found:')
# iterate over entities and print
for entity in sentence.get_spans('ner'):
    print(entity)

This yields the following output:

Span [5,6]: "Henrique Dias"   [− Labels: NOME (0.9735)]
Span [31,32]: "Marcelo Arocha"   [− Labels: NOME (0.9803)]

So, the entities "Henrique Dias" (labeled as a nome) and "Marcelo Arocha" (labeled as a nome) are found in the sentence.
