Knowledge Graph by Google

In the next few days, Google will be rolling out Knowledge Graph as part of Google search.  This tool will help you refine your search and present more relevant search results.  For example, it you search for lion, it will help you narrow your search to the animal or the Mac operating system.

Check out the video below for a closer look or go to http://www.google.com/insidesearch/features/search/knowledge.html for more information.
