XLM-RoBERTa Tourism Sentiment Classifier

Fine-tuned XLM-RoBERTa model for multilingual tourism comment sentiment analysis.

Model Description

This model classifies tourism comments in 39 languages into 3 sentiment categories:

• positive (Positive/Tích cực)
• neutral (Neutral/Trung lập)
• negative (Negative/Tiêu cực)

Training Data

• Languages: 39 languages (English, Korean, Russian, German, French, Italian, Spanish, and 32 more)
• Dataset: 2,123 multilingual tourism comments from social media
• Sources: Google Maps, TikTok, YouTube, Facebook
• Split: 80% train (1,698), 20% validation (425)
• Quality: Filtered for meaningful content (min 10 words)

Usage

import torch
import torch.nn as nn
from transformers import AutoTokenizer, AutoModel

# Define model architecture
class XLMRobertaSentimentClassifier(nn.Module):
    def __init__(self, n_classes=3, dropout=0.3):
        super(XLMRobertaSentimentClassifier, self).__init__()
        self.xlm_roberta = AutoModel.from_pretrained('xlm-roberta-base')
        self.dropout = nn.Dropout(dropout)
        self.classifier = nn.Linear(self.xlm_roberta.config.hidden_size, n_classes)
        
    def forward(self, input_ids, attention_mask):
        outputs = self.xlm_roberta(input_ids=input_ids, attention_mask=attention_mask)
        pooled_output = outputs[0][:, 0, :]
        pooled_output = self.dropout(pooled_output)
        logits = self.classifier(pooled_output)
        return logits

# Load model
device = torch.device('cuda' if torch.cuda.is_available() else 'cpu')
tokenizer = AutoTokenizer.from_pretrained('xlm-roberta-base')

model = XLMRobertaSentimentClassifier(n_classes=3)
checkpoint = torch.load('xlm_sentiment_best_model.pt', map_location=device)
model.load_state_dict(checkpoint['model_state_dict'])
model = model.to(device)
model.eval()

# Predict (works with any language!)
text = "Beautiful beach, loved it!"  # English
# text = "아름다운 해변이에요!"  # Korean
# text = "Sehr schöner Strand!"  # German

encoding = tokenizer(
    text,
    add_special_tokens=True,
    max_length=256,
    padding='max_length',
    truncation=True,
    return_attention_mask=True,
    return_tensors='pt'
)

input_ids = encoding['input_ids'].to(device)
attention_mask = encoding['attention_mask'].to(device)

with torch.no_grad():
    outputs = model(input_ids=input_ids, attention_mask=attention_mask)
    probs = torch.softmax(outputs, dim=1)
    confidence, predicted = torch.max(probs, dim=1)

sentiments = ['positive', 'neutral', 'negative']
print(f"Sentiment: {sentiments[predicted.item()]} ({confidence.item():.4f})")
# Output: Sentiment: positive (0.9981)

Features

✅ Truly Multilingual: Works with 39+ languages out of the box ✅ High Accuracy: 80.71% overall accuracy across all languages ✅ Zero-Shot Capability: Can handle new languages not in training set ✅ Production Ready: Used in real-world tourism monitoring system ✅ Fast Inference: ~80ms per comment on GPU

Limitations

• Lower performance on neutral class due to data imbalance (11.8% of data)
• English-dominant training data (51.3%) may affect non-English performance
• Trained on tourism domain (may not generalize to other domains)
• Requires more data for minority languages

Use Cases

• International tourism review sentiment analysis
• Multilingual social media monitoring
• Cross-cultural customer feedback analysis
• Global tourism demand analysis
• Automated content moderation for tourism platforms
