SAN FRANCISCO (AP) — Google is introducing a new tool, designed to make its search engine smarter.The new feature debuting Wednesday draws from a Google-built database of more than 500 million people, places and commonly requested things to provide a summary of vital information alongside the main search results.Google Inc. spent the past two years poring through online encyclopedia Wikipedia, the CIA Factbook and other sources to expand a database of 12 million items that it picked up as part of its 2010 acquisition of Metaweb.The information warehouse, which Google calls a “Knowledge Graph,” is an attempt by the Internet’s dominant search engine to provide answers as quickly and concisely as possible so users don’t have to sift through a hodgepodge of Web links displayed on the main results page.The nuggets of information will appear in boxes to the right of the main search results. Google will gradually roll out the feature to its logged-in users in the U.S.
