Twitterlytics grew out of the question: can I access the Twitter stream programmatically and perform a sentiment analysis on the content returned? The answer is: yes. Create multiple Twitter queries. Analyze key words used in the respective context most frequently. Automatic, repetitive polling from Twitter. Attribute analysis based on multiple attributes and keywords using scoring. Calculation of averages for comparability. Top 20 word analysis taking into account a user-definable list of words to be ignored.
