Google has announced the upgrade of its search engine that allows users to find the necessary information easier. The new search engine features ‘Knowledge Graph,’a service that provides results with better accuracy and additional information.

Users will be able to filter results and see a brief information of relevant content on the right side of the page. To create the new database, Google used a variety of knowledge databases, including Freebase, which it bought in 2010, Wikipedia, Google Local, Google Maps and Google Shopping. The service is based on the a two-year effort to build a collection of 500 million people, places and things on the Internet that are identified by how they’re connected, according to Google’s Ben Gomes.

To avoid misinformation, Google’s Knowledge Graph includes an error reporting system. When users find misinformation, Google will share it with the source and the knowledge graph will ‘remember’ it.

The new Google service comes soon after Microsoft has upgraded its Bing search engine to make it more social. Google’s answer is aimed to maintain its user base. The new ‘smart’ search engine can distinguish names and notions. For example, it differentiates a sports team name, such as ‘Kings’ and the TV series.

Google’s Knowledge Graph will roll out across the U.S. in the coming days. Later, it will go global.
