How did we gather the info? Pulse data scientist Doug Puett explains the process:
“The Pulse data team used Latent Dirichlet Allocation, a statistics technique that categorizes articles based on key words within them. Using the Pulse ‘Best of Politics’ feed, we were able to find the key words that were most often mentioned over the course of the year, and then grouped those words into larger topics. We plotted the number of documents per day for each topic, and compared the issues with the number of headlines featuring ‘Romney’ or ‘Obama’.”
