SAN FRANCISCO — Google (GOOG) 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.
Mountain View-based Google. 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.
