Sentiment Analysis: A New Approach for Effective Use of Linguistic Knowledge and Exploiting Similarities in a Set of Documents to be Classified

چکیده
Sentiment Analysis aims at determining the overall polarity of a document, for instance, identifying whether a movie review appreciates or criticizes a movie.

The technique is made more effective by incorporating linguistic knowledge gathered through Wordnet1 synonymy graphs. A method to improve the accuracy of classification over a set of test documents is finally given.
