BuzzChurn is a software product of The Frederick S. Pardee Center for International Futures, the home of long-term forecasting and global trend analysis at the Josef Korbel School of International Studies on the University of Denver campus.

The BuzzChurn computer model collects hundreds of news feeds from across the Web hourly and performs a statistical analysis of keyword occurrence in those feeds on a country-by-country basis. The keywords are selected with an emphasis on conflict as well as global economic and social stability.

The BuzzChurn bubble maps will animate the past six or 24 hours of news activity. Here's how you read the maps:

  • Countries experiencing the hottest global news exposure are shown in RED on the BuzzChurn maps. In these "hot" countries, keyword occurrence is stronger compared to their seven day moving window average.
  • Countries that are "cooling" compared to their moving average are shown in BLUE.
  • The size of the bubbles on the bubble map reflects the absolute number of stories generating keyword hits for that country.
  • The slider on the BuzzChurn bubble map can be used to navigate back and forth in time in one hour increments.
  • At any time-point, you can click on a country's bubble to see headlines from the top keyword-intensive stories for that hour.
