The CBS News/TNS tool measures and evaluates the Twitter conversation about the Republican presidential candidates on a daily basis. It provides the volume of Tweets per candidate and the proportion of positive and negative non-informational English-language Tweets. Tweets are categorized based on a text mining algorithm developed by TNS and Vigiglobe, specifically designed to analyze online political discussions, and that extracts the sentiment contained in each Tweet. This allows second to second monitoring of people's opinions on Twitter, providing instant reads on the current Twitter conversation about political candidates.
