The core method used in this research is measuring the resemblance between phrase frequencies in the newspaper and phrase frequencies in the 2005 Congressional Record. The result of comparing these frequencies plays a key indicator to identify the newspaper's ideology. Gentzkow and Shapiro interpret 'how many times the newspaper used congressional phrases' into 'how much slanted the newspaper's ideology is.'
However, does the phrase frequencies necessarily imply the degree of slant? Some newspapers might use "death tax" rather than "estate tax" simply because it could be easy for readers to understand the new policy. How can we sort out this kind of problem?
