Vietnamese Sentiment Analysis Model

This model is fine-tuned from vinai/phobert-base for Vietnamese sentiment analysis with entity context.

Model description

The model classifies text sentiment into three categories:

• NEGATIVE (0)
• NEUTRAL (1)
• POSITIVE (2)

It is specifically designed to analyze sentiment toward a specific entity mentioned in the text.

Intended uses & limitations

The model is intended to be used for Vietnamese sentiment analysis, specifically when analyzing sentiment toward a named entity.

How to use

from transformers import AutoTokenizer, AutoModelForSequenceClassification
import torch

# Load model and tokenizer
tokenizer = AutoTokenizer.from_pretrained("Khoa/vietnamese-sentiment-analysis-with-entity")
model = AutoModelForSequenceClassification.from_pretrained("Khoa/vietnamese-sentiment-analysis-with-entity")

# Function to predict sentiment
def predict_sentiment(text, entity, model, tokenizer):
    combined_text = f"Đối với {entity}, {text}"
    inputs = tokenizer(combined_text, return_tensors="pt", truncation=True, padding=True)

    with torch.no_grad():
        outputs = model(**inputs)
        predictions = torch.nn.functional.softmax(outputs.logits, dim=-1)
        predicted_class = torch.argmax(predictions, dim=-1).item()

    sentiment_labels = {0: "NEGATIVE", 1: "NEUTRAL", 2: "POSITIVE"}
    return sentiment_labels[predicted_class], predictions[0].tolist()

# Example usage
text = "Món ăn rất ngon nhưng giá hơi đắt"
entity = "Nhà hàng ABC"
sentiment, confidence = predict_sentiment(text, entity, model, tokenizer)
print(f"Sentiment: {sentiment}")

Training procedure

The model was fine-tuned on a custom Vietnamese dataset with entity-specific sentiment annotations.
