SGI's Big Brain Computer Powers the Global Twitter Heartbeat -- #tweetbeat
SGI has partnered with 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 to create the first ever real-time combined population, tone and geographic analysis and heat map visualization of Tweets on a SGI UV 2000, the Big Brain computer. During the Supercomputing Conference 2012, live up-to-the-moment heat maps were made available to show the sentiment on Twitter.
The Global Twitter Heartbeat project performs real-time stream processing of ten percent of Twitter's 500 million daily tweets as they are posted. The project analyzes 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 ingest to data analysis to heat map visual can easily be completed in less than a second.
The project looked at two significant recent events - Hurricane Sandy and the U.S. Presidential Election. In both events, millions of tweets were sent, making Twitter a significant platform for communicating what was happening at every moment.

During Hurricane Sandy, the project observed a huge increase amount of tweets discussing the weather event, as a percentage of overall tweets.
