m-e5-small-hosrev

Overview

Vietnamese aspect-category sentiment classification model for hospital reviews. The model predicts sentiment for 13 aspect categories covering facilities, medical staff, and overall experience.

Dataset

• Dataset: HosRev HosRev is a Vietnamese hospital review dataset for Aspect-Category Sentiment Analysis (ACSA). The data contains reviews of hospitals in Ho Chi Minh City with aspect-category sentiment labels.

Data Format

• Review is the input text column.
• Each remaining column is one aspect-category label encoded as 0/1/2/3.

Splits

• Train: 4566 samples
• Validation: 978 samples
• Test: 979 samples

Checkpoint Metrics

• loss: 0.2834
• accuracy: 0.8970

Usage

Load the model with trust_remote_code=True because this repository contains custom modeling code.

from transformers import AutoModelForSequenceClassification, AutoTokenizer

repo_id = "NeoCyber/m-e5-small-hosrev"
tokenizer = AutoTokenizer.from_pretrained(repo_id)
model = AutoModelForSequenceClassification.from_pretrained(
    repo_id,
    trust_remote_code=True,
)

texts = ["Bác sĩ nhiệt tình và giải thích rất dễ hiểu."]
inputs = tokenizer(texts, return_tensors="pt", truncation=True, padding=True)
outputs = model(**inputs)
predictions = model.decode_predictions(outputs.logits)
print(predictions)

Notes

• The repository includes custom configuration_*.py and modeling_*.py files required by transformers AutoClasses.
• outputs.logits has shape [batch_size, num_aspects, 4] and model.decode_predictions(...) maps logits back to aspect-level labels.
