SAN FRANCISCO (Dow Jones) -- Google Inc. (GOOG) said Wednesday it is rolling out an extensive update to its dominant search engine by using massive troves of data to refine the answers it provides to user queries on specific topics.
The "Knowledge Graph" being rolled out by Google within its search service over the coming weeks 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.
An example would be a search for the term "Kings," which could be a professional basketball team, hockey team or TV series, said Google Fellow Ben Gomes.
Using the new feature, Google will be able to figure out which "Kings" users mean by giving them some options, and then presenting them with a box on the right of search results with related photos and other data.
"There's only so far that words themselves can take us," Gomes said. "What we need to do is create a map of all the things in the real world, and the relationships between them."
The new service builds on Google's purchase of start-up Metaweb Technologies Inc., which had developed the Freebase database of information, in 2010.
Other data sources it has tapped include Google's own Books and Local services. In addition, "We have cars driving all over the place learning about places and businesses," Gomes said, in reference to Google's Street View cars which roam the streets gathering mapping and other data.
Gomes said he doesn't anticipate the new feature will detract much from the search links paid for by advertisers, which traditionally appear on the right of a Google search page: "It has no significant impact on our ads."
He declined to say what percentage of total Google searches would be affected.
The move could bolster other Google initiatives, such as its Wallet mobile payment service. For example, Gomes noted that a search on a phone for a particular musician could return information including the date and time of their next concert.
The new feature is sweeping amplification of the so-called OneBox results that Google has been presenting alongside some search results for years, which include small bits of in-house data compiled by Google.
Google held a 66.5% share of the U.S. search market as of last month, according to comScore data. That compares to a combined 28.9% share for Microsoft Corp. (MSFT) and Yahoo Inc. (YHOO), which have teamed up in a search alliance.
