摘要：Complicated text understanding technology which extracts opinion, and sentiment analysis is called opinion mining. Building systems to collect/examine opinions about a product in blog posts, comments, and reviews/tweets is sentiment analysis. Product reviews are the focus of existing work on review mining and summarization. This study focuses on movie reviews, investigating opinion classification of online movie reviews based on opinion/corpus words used regularly in reviewed documents.
