Multi-Domain Sentiment Dataset is a multi-domain sentiment analysis dataset that collects reviews of products from different categories (i.e., domains) on the Amazon platform. Some products (such as books and DVDs) have hundreds of thousands of reviews, while other products (such as musical instruments) have only a few hundred reviews. These buyer reviews include star ratings (1 star-5 stars), buyer username, location, product name, review title, date, and text, and support conversion into binary labels.
