The Knowledge Graph from Google isn’t rooted merely in public sources like Freebase, the CIA World Factbook and Wikipedia. It is augmented at a much vaster scale. It focuses on breadth and depth, which is really comprehensive. It contains over 500 million objects currently, as well as over 3.5 billion facts about and relationships that exist among these different objects – based on what searchers look search for, and what is found out on the web.
It can help users make certain unexpected discoveries as well. For example, one might end up learning a sudden new fact or perhaps new connection, which would prompt a novel line of inquiry or thought. Google engineers work on a premise that the perfect engine should be capable to exactly understand what a user means and then give them back exactly what they want, grasping the context and connotation of the query. And it can now even help answer the next question sometimes before you have asked it, since the facts it shows are apparently informed by what other like-minded people have looked for previously.

Added intelligence in search methodology

Here are  few examples of added intelligence apparent in the new Google search functionality:

• The information it shows for Tom Cruise, for example, answers a large percentage of next queries fans ask about the star. In fact, many serendipitous discoveries that can be made utilizing the graph are through the feature called ‘People also search for’. Google has started to roll out gradually this version of the Knowledge Graph to U.S. users. So if you’ve an unexpected question pop into your mind while on the move, tablets and smartphones Google will come in handy since it puts the precise information online right at your fingertips, a process that has been simplified with the functionality for wireless devices.
• The idea of imparting this added intelligence is to give people a more complete and holistic picture of their interest, offer smarter results, and pique their curiosity on new, interesting topics. This is what the Knowledge Graph intends to do: To make search much more intelligent.
• A test search for the query on Barack Obama would now yield a linked photo from his Google Plus page, a bio sourced from Wikipedia, his date and place of birth with a link for details on Honolulu, his education with links to relevant institutions, the President’s net worth, his children’s names with allied links, and linked titles of his important books. Just across the bottom of the comprehensive Knowledge Graph will be thumbnails for links for Mitt Romney, Michelle Obama, Ron Paul, and Rick Santorum.
• If you happen to click on Santorum, what you will get is his primary results amidst those in the main column plus his nickname Rooster apart from other details highlighted in the Knowledge Graph box. A search for ‘The Rock’ will result in a box carrying details of actor Dwayne Johnson and for the film starring Sean Connery below a box. Knowledge Graph, in essence, can provide more specific answer about those random trivia questions in your head. It may prompt the search engine users to spend more quality time on the site as they continue to click deeper and deeper into a favorite or any other random topic.

Of course, Google agrees that all the results won’t be perfect hence it has invited its users to give feedback using a link highlighted at the bottom of the right-rail box.
