TweetMood

TweetMood provides near real time sentiment analysis of Twitter streams and allows for filtering based on user supplied hashtags or search terms.

What is sentiment analysis? Sentiment analysis is the art/science of natural language processing used to determine a 'mood' from a set of expressions, or in this case, the tweet contents.
We are always working on improving our algorithms and will push out updates with incremental improvements as they are made.
TweetMood does not require a Twitter account as it is designed to use the Twitter live streams.
TweetMood was designed with live events in mind. For instance, if you are watching The Voice you can enter all of the associated hashtags or search terms regarding and the 'mood' will be calculated.
