With the development of web technologies, an increasing amount of opinions are published online every day. People rely on the reviews more than before to help determine the quality of product in which they are interested. This system on movie reviews is developed towards conducting sentiment analysis on movie reviews. It can help relieve the burden for people of viewing a huge amount of reviews. First, the system analyses the reviews and categorizes them into three different classifications: positive, negative and neutral. This analysis is based on the feature words that extracted from review text. Then the review result with sentiment score is shown in different visualizations. Those visualizations give user an overview of reviews to help them gain an impression of product.
