Pang Movie Reviews
Bo Pang distributes a number of versions of the widely-used movie review dataset. The original version has 700 positive and 700 negative reviews, but other data (like a larger pool of reviews harvested from IMDB, subjective and objective sentences, etc) are also distributed from the same page. Pang also maintains an extensive list of papers that used the movie review dataset.
