Sentiment Analysis/Opinion Mining Resources

According to Wikipedia, Sentiment analysis or opinion mining refers to the application of natural language processing, computational linguistics, and text analytics to identify and extract subjective information in source materials. The rise of social media such as blogs (Blogger, WordPress, TypePad) and social networks (Facebook, LinkedIn, Ning) has fueled interest in sentiment analysis. With the proliferation of reviews, ratings, recommendations and other forms of online expression, online opinion has turned into a kind of virtual currency for businesses looking to market their products, identify new opportunities and manage their reputations. As businesses look to automate the process of filtering out the noise, understanding the conversations, identifying the relevant content and actioning it appropriately, many are now looking to the field of sentiment analysis.

For example, if you are considering buying an Apple iPad, you can check latest Twitter sentiment (positive, negative or neutral) towards the product using online Twitter Sentiment site as below:

Other sites that offer such similar applications are:
1. TweetFeel – Tweetfeel monitors positive and negative feelings in twitter conversations about stuff like movies, musicians, TV shows and popular brands.
