bert-base-portuguese-cased-porsimplessent

BERTimbau base for Text Simplification

This is the neuralmind/bert-base-portuguese-cased model finetuned for Text Simplification with the PorSimplesSent dataset. This model is suitable for Portuguese.

• Git Repo: Evaluation of Portuguese Language Models.
• Demo: Hugging Face Space: Portuguese Text Simplification

Labels:

• 0 : Sentence A is more simple than Sentence B.
• 1 : The two sentences are equally simple.
• 2 : Sentence B is more simple than Sentence A.

Full classification example

from transformers import AutoModelForSequenceClassification, AutoTokenizer, AutoConfig
import numpy as np
import torch
from scipy.special import softmax

model_name = "ruanchaves/bert-base-portuguese-cased-porsimplessent"
s1 = "O preço para instalar um DVD player no carro fica entre R$ 2 mil e R$ 5 mil."
s2 = "Instalar um DVD player no carro tem preço médio entre R$ 2 mil e R$ 5 mil."
model = AutoModelForSequenceClassification.from_pretrained(model_name)
tokenizer = AutoTokenizer.from_pretrained(model_name)
config = AutoConfig.from_pretrained(model_name)
model_input = tokenizer(*([s1], [s2]), padding=True, return_tensors="pt")
with torch.no_grad():
    output = model(**model_input)
    scores = output[0][0].detach().numpy()
    scores = softmax(scores)
    ranking = np.argsort(scores)
    ranking = ranking[::-1]
    for i in range(scores.shape[0]):
        l = config.id2label[ranking[i]]
        s = scores[ranking[i]]
        print(f"{i+1}) Label: {l} Score: {np.round(float(s), 4)}")
