The latest heat map offers a real-time analysis of random data using supercomputers. One such is SGI UV 2000 Big Brain supercomputer at the University of Illinois which processes an impressive amount of raw information from the web very quickly and tells how everybody is feeling on Twitter right now. Much more than the Twitter sentiments.

The realtime Twitter tracking has been able to create more information regarding the people’s view, both positive and negative sentiments, prediction analysis, and much more. The Global Heartbeat Project, a partnership between supercomputer supplier SGI Kalev H. Leetaru of the University of Illinois and Dr. Shaowen Wang of the CyberInfrastructure and Geospatial Information (CIGI) Laboratory at the University of Illinois at Urbana-Champaign, also analyzed tweets during superstorm Sandy. Using red for negative tweets and blue for positive tweets regarding Sandy, the map reveals the mood in various areas of the U.S. as Sandy progressed up the East Coast.

The below video is all about The Global Twitter Heartbeat project performs real-time stream processing of ten percent of Twitter’s 400M daily tweets as they are posted. The project analyses every tweet to assign location (not just GPS-tagged tweets, but processing the text of the tweet itself), and tone values and then visualizes the conversation in a heat map infographic that combines and displays tweet location, intensity and tone. With SGI UV, the entire process from data analysis to heat map was produced once per second.
