Using data from May 2010 to January 2011, the tool analyzes click-through rates to 155 top U.S. political blogs with a particular political leaning.

The categorization of the blogs is based on the paper “A Tale of Two Blogospheres: Discursive Practices on the Left and Right” by Yochai Benkler and Aaron Shaw” published by the Berkman Center for Internet and Society.
According to Yahoo, the project is an intermediate output of collaboration between Yahoo! research labs Barcelona and the University of Amsterdam’s Digital Methods Initiative.

We look into all the queries landing on 155 top U.S. political blogs annotated with a political leaning.* Subsequently we assign a leaning to each query, proportional to the number of times it lands on a blog with a particular leaning. The resulting data set consists of classified queries, made by hundreds of thousands of users.
