Google search gets smarter


17/05/2012

Technology called "Knowledge Graph" (Russo "Information Earl"), designed to distinguish different meanings of certain key words have been launched in the United States and eventually will operate around the world.

During the demonstration, was produced by a search for "Kings" (Russo Kings). This word can mean both the hockey team from Los Angeles, and the basketball team from Sacramento, as well as the eponymous television series, or, most of these monarchs.

With the Knowledge Graph, the results will be divided into categories that are associated with this word. In the above example, users will be presented separate results for the hockey and basketball teams, as well as for the TV series.

Clicking on one of these categories, the user will get exactly the results that he needed.

"It allows us to provide the people what they are looking for," - said Jack Menzel from Google.

More specific requests, for example, a celebrity’s name will now be accompanied by a little background information as well as links to related to your search queries.

According to Menzel, the original version of the Knowledge Graph contains information about 500 million people, places and things, and uses the 3.5 billion specifying attributes and relationships that define the categories for these words.

Search engine Google has rapidly adjusts its algorithm to the collection of information from databases such as Freebase and Wikipedia, in order to determine the context of words.

Search query name of a specific person, such as an architect, will be processed Knowledge Graph, which will offer a variety of categories, such as biographical information or projects performed by him.

Google also added to the search results section with unexpected facts.

For example, when searching for information about the creator of the animated series "The Simpsons" Matt Groening, you will be able to simultaneously learn the names of his parents and sisters were the same as the names of the characters he created the animated series - Homer, Margaret and Lisa.

"Text strings are ambiguous and we need to make some changes in order to teach our system to understand the real-world objects," - said Ben Gomes of Google. "This is a very interesting problem that we solve for the past two years."

Users are given the opportunity to tell Google about a possible error on the part of Knowledge Graph, by clicking on a link.

"Not everything is working correctly," - said Gomes. "While we are putting into this project a lot of effort, but even after reaching the ideal - the facts are changed every day."

"This is especially useful for mobile phones and tablets", - he said.

Google’s share of the search market in the U.S. is currently 66.5%, and the search engine Bing from Microsoft - ranked second, with a share of 15.4%, according to the company comScore.
