ReviewBERT: Romanian Product Review Classifier

🧠 Model Overview

ReviewBERT is a fine-tuned Romanian language BERT model designed to classify product reviews on a scale from 1 to 5. It is based on the readerbench/RoBERT-base checkpoint and was fine-tuned using a dataset of 15826 Romanian-language product reviews on cosmetics. The task is multiclass sentiment classification, where:

1 = Very Negative
2 = Negative
3 = Neutral
4 = Positive
5 = Very Positive

💡 How to Use

python

from transformers import AutoTokenizer, AutoModelForSequenceClassification
from transformers import pipeline

model = AutoModelForSequenceClassification.from_pretrained("catalina-mawas/romanian-product-reviews")
tokenizer = AutoTokenizer.from_pretrained("catalina-mawas/romanian-product-reviews")

clf = pipeline("text-classification", model=model, tokenizer=tokenizer)
clf("Produsul a fost groaznic, nu recomand.")

⚠️ Limitations & Biases

The model was trained exclusively on cosmetics product reviews and may not generalize well to other Romanian-language domains.
Sentiment labels (especially mid-range scores like 2–4) are inherently subjective and could reflect user bias.
