… Today, we’re launching the Twitter Political Index, a daily measurement of Twitter users’ feelings towards the candidates as expressed in nearly two million Tweets each week.
The Twitter Political Index is built in partnership with the data analysis team at Topsy (@Topsy) and two respected polling firms: The Mellman Group (@markmellman) and North Star Opinion Research (@northstaropin).
Each day, the Index evaluates and weighs the sentiment of Tweets mentioning Obama or Romney relative to the more than 400 million Tweets sent on all other topics. [cont.]
