Model description

El modelo base bert-base-cased es una versión pre-entrenada del popular modelo de lenguaje BERT de Google. Inicialmente fue entrenado en grandes cantidades de texto para aprender representaciones densas de palabras y secuencias. Posteriormente, este modelo toma la arquitectura y pesos pre-entrenados de bert-base-cased y los ajusta aún más en la tarea específica de Reconocimiento de Entidades Nombradas (NER por sus siglas en inglés) utilizando el conjunto de datos conll2002.

How to Use

from transformers import AutoTokenizer, AutoModelForTokenClassification, pipeline

tokenizer = AutoTokenizer.from_pretrained("JoshuaAAX/bert-finetuned-ner")
model = AutoModelForTokenClassification.from_pretrained("JoshuaAAX/bert-finetuned-ner")


text = "La Federación nacional de cafeteros de Colombia es una entidad del estado. El primer presidente el Dr Augusto Guerra contó con el aval de la Asociación Colombiana de Aviación."


ner_pipeline= pipeline("ner", model=model, tokenizer=tokenizer, aggregation_strategy="max")
ner_pipeline(text)
