                 A great example of sentiment analysis occurs around a movie release.  When a big film is released there are thousands of blog posts and hundreds of thousands of tweets published about the subject. By analyzing the feelings of these tweets and posts we can get a sense of how the public is responding to the film. This is like running the world’s largest focus group in real time. When Inception was released there was a constant stream of tweets and blog posts about the film for weeks. Sentiment analysis of all of these posts showed the audience reaction was enormously positive and this was reflected in the films box office numbers.sentiment analysis can be used to monitor customer reactions to products and services over time. It offers a great defense against brand damaging events as problems can be spotted at their source.

But human phrasing is enormously complex. So sentiment algorithms prove to be just a bit more accurate than flipping a coin.
