Google Knowledge Graph-new update

Google launched its much awaited “Knowledge Graph” today. Apart from traditional search results this new technology from Google shows popular and well known facts about people, places & things.  The new technology has given Google a new way of searching. Earlier the searches were based on pages that matched the query term. The new technology searches on the basis of “entities” or “concepts” the keyword describes.

Knowledge Graph - “Graph” as we all know is an abstract representation that shows set of objects connected by links. Google used “link graph” concept to model how pages in the search, link to each other, with the aim of determining, what are popular and relevant searches for that particular keyword. Facebook used a “social graph” in order to understand how people are related. “Knowledge Graph” is Google expression, which shows how Google is building associations between people, place, & things and it shows information about these entities. Google states for Knowledge Graph it has compiled more than 3.5 billion facts. It includes information and relations between 500 million entities. The entities are generally persons, places & things.

Let us have a look at some of the prominent categories of objects Google has information and facts about.
  • Actors, Movies, Producers, Directors.
  • Cities & Countries.
  • Art Works and Museums.
  • Islands, Lakes & Lighthouses.
  • Music Albums, Artist & Music Groups.
  • Planets, Astronauts, Space & Spacecraft.
  • Sports Teams.
These are some of the categories. The most important thing is relationships between the facts. The relationships help Knowledge Graph to link which actors did a particular movie or which player or team has won a particular tournament. Knowledge Graph is going to bring a revolution in the way of searching.
