Google Inc has
overhauled its search algorithm, the foundation of the Internet's
dominant search engine, to better cope with the longer, more complex
queries it has been getting from Web users.
Amit Singhal, senior vice
president of search, told reporters on Thursday that the company
launched its latest "Hummingbird" algorithm about a month ago and that
it currently affects 90 percent of worldwide searches via Google.
Google
is trying to keep pace with the evolution of Internet usage. As search
queries get more complicated, traditional "Boolean" or keyword-based
systems begin deteriorating because of the need to match concepts and
meanings in addition to words.
"Hummingbird"
is the company's effort to match the meaning of queries with that of
documents on the Internet, said Singhal from the Menlo Park garage where
Google founders Larry Page and Sergey Brin conceived their
now-ubiquitous search engine.
"Remember
what it was like to search in 1998? You'd sit down and boot up your
bulky computer, dial up on your squawky modem, type in some keywords,
and get 10 blue links to websites that had those words," Singhal wrote
in a separate blogpost.
"The world
has changed so much since then: billions of people have come online, the
Web has grown exponentially, and now you can ask any question on the
powerful little device in your pocket."
Page
and Brin set up shop in the garage of Susan Wojcicki -- now a senior
Google executive -- in September 1998, around the time they incorporated
their company. This week marks the 15th anniversary of their
collaboration.
