Automatically highlighting the central words of the candidates’ debate rhetoric.
As the primary election season continues to other important contests in the U.S., we continue our data-driven analysis of the presidential candidates. Previously, we have looked at the most distinctive words used by voters of each candidate and at the distinctive words of each candidate in debate speeches. This time, we were interested in what are the core concepts in each candidate’s rhetoric. To uncover this, we used a different algorithm that highlights the most ‘central’ words and phrases of each candidate those which appear over and over to bridge the distinct themes of each candidate (see Technical Section for more details).
