Sentiment Analysis Final Year Projects 2026

Sentiment analysis classifies text as positive, negative, neutral — or into finer emotion and aspect categories. Student projects range from classical bag-of-words models to BERT fine-tuning, aspect-based sentiment (ABSA), social media streams and explainable predictions on public benchmarks.

Below: 80+ topics with tools and representative datasets.
