even twitter is aplace where in the tweets deliver reviews, but seeking to reap the generalunderstanding of these unstructured records (reviews) may be very timeingesting. those unstructured statistics (reviews) on a specific web site areseen through the users and as a result growing an image about the products orofferings and as a result finally producing a sure judgment. these reviews arethen being generalized to acquire feedbacks for extraordinary purposes to offerbeneficial reviews in which we use sentiment analysis.
