Big Data - The Sentiment of the World Throughout History Through Wikipedia

The SGI Wikipedia Project
Kalev Leetaru turned to Wikipedia and together with SGI has created the first-ever historical mapping and exploration of the full text contents of the English-language edition of Wikipedia, in time and space, with visualizations of modern history captured in under a day.

See the positive or negative sentiments unfold through Wikipedia through space and time.  Each location is plotted against the date referenced and cross referenced when mentioned with other locations.  The sentiment of the reference is expressed from red to green to reflect negative to positive. All done using an SGI UV Shared Memory System.

A year on year analysis of social media from January 2010 clearly demonstrates the rapid growth of the major networks.

While Wikipedia is chugging along with 5,000 new contributors Facebook continues to blitz the opposition, signing up 290 million new accounts over the same period.

Note also that users accessing Facebook on their mobile device has grown by over 200 percent to 200 million.  This growth trend will continue

Another significant mover has been the professional network, LinkedIn with a 100% growth and Flickr has now features 5 billion images, which represents a 25% increase in their activity.
