Google Revamps Search Engine To Make It Smarter

Google Inc.announced plans Wednesday for an extensive update to its dominant search engine, using troves of data to refine the answers it provides to user queries on specific topics. The technology known as "Knowledge Graph" is being rolled out by Google within its search service over the coming weeks, the company said. It uses a database of about 500 million people, places and things compiled by the company to figure out exactly what users are looking for, and present them with additional, related information.
