The Sentiment, online app allows you to view tweets containing the search phrase you enter. The tweets are classified according to their sentiment as Positive, Negative and Neutral. Duplicates have been removed along with possible spam.
The sentiment of each tweet is estimated by looking for the presence of words with known sentiment within each tweet. Based on this initial analysis each tweet is classified as either positive, negative or neutral and displayed in the corresponding section of the page. The word list section contains the words collected from all the tweets.
