Google's flagship service, the search engine has become a lot smarter with the introduction of a new enhancement termed as the `Knowledge Graph'.

The company enhanced its online search engine to include sets of associated facts with each user query. Knowledge Graph shows much deeper understanding of the questions typed by the users. Google's knowledge graph will include associated data about a specific search query.

Earlier enhancements like Search Plus Your World and Universal Search aimed at expanding the data returned by the Google search engine or optimized the speed of delivery of outputs. However, the new Google's Knowledge Graph is an aim to make the search engine simply smarter.

The search engine will now display a set of facts in the right-hand sidebar panel along with the usual search results. This may mean that users looking for popular facts about a personality or any other object will simply find the extract on the Google search page, which avoids the need to clock on any of the link presented by the search engine.

Google SVP of engineering Amit Singhal said that the enhancement comes as a result of Google's understanding of what the users want and a better sense of how facts are related. The tool will use a database of about 500 million people, places and things that is put together by the company to better understand what the users are looking for in their search.
