Car Review Sentiment, DistilBERT

distilbert-base-uncased fine-tuned for 3-class sentiment on real Edmunds car owner reviews, for a per-aspect word-of-mouth analyzer.

• Labels: 0 negative, 1 neutral, 2 positive
• Data: Edmunds consumer car reviews, florentgbelidji/car-reviews, labels by distant supervision from the 1 to 5 star rating.
• Test set of 3,652 held-out reviews: accuracy 86.7 percent, macro-F1 0.566.
• Known limits, measured: negation and sarcasm are hard. See the stress tests in the project repo. Deploy with confidence-gated abstention.
