The natural language text is analyzed by using sentiment analysis and classified into positive, negative or neutral based on the human emotions, sentiments, opinions expressed in the text. The user reviews and comments on movies on the web are increasing day by day. And to make a decision in movie planning, these reviews are useful for other users. To perform manual analysis of a huge number of reviews is practically not possible. Hence, to solve such problem we require an automated approach of a machine that mines the overall sentiment or opinion polarity from the reviews. This paper analyses the movie reviews using sentiment analysis and text mining techniques. In this technique, Sentiment scores are assigned to the aspects with respect to the words used. Sentiment analysis is performed at three different levels. These are documented level, sentence level, and aspect level. Most of the previous work is done in the document or sentence-level sentiment analysis. We focus on the aspect level opinion mining of movie reviews. From a given set of reviews of a movie, we get a sentiment profile. By using SentiWordNet different approaches are proposed for sentiment analysis. It contains two-word phrases and linguistic rules together for opinion mining. The Send score algorithm is devised to perform this function. For attempting to mine and understand the user's feedback data, we perform an aspect level sentiment extraction. To predict the polarity of the reviews, a priority-based algorithm forms the rule base for the classifier. First, we perform a cleanup on the review data, then Send score algorithm is utilized to generate the aspect document matrix.
