The Knowledge Graph is a knowledge base used by Google to enhance its search engine's search results with semantic-search information gathered from a wide variety of sources. Knowledge Graph display was added to Google's search engine in 2012, starting in the United States, having been announced on May 16, 2012. It provides structured and detailed information about the topic in addition to a list of links to other sites. The goal is that users would be able to use this information to resolve their query without having to navigate to other sites and assemble the information themselves.
According to Google, this information is derived from many sources, including the CIA World Factbook, Freebase and Wikipedia.The feature is similar in intent to answer engines such as Ask Jeeves and Wolfram Alpha. As of 2012, its semantic network contained over 500 million objects and more than 3.5 billion facts about and relationships between these different objects which are used to understand the meaning of the keywords entered for the search.Source : Wikipedia
Google’s Knowledge Graph is launched in all countries for English search.It is amazing.The new Knowledge Graph will appear in the form of short snippets to the right column of its results and provide users more information on a topic and help users explore related items as well.
What is special in Google’s Knowledge Graph?
Information from the Knowledge Graph is available on desktop, tablet, and your smartphone. So wherever you search on Google, you’ll find that answers and discovery are at your fingertips.
Language can be ambiguous—do you mean Rio the city, the movie, or the casino? With the Knowledge Graph, Google can understand the difference, helping you more precisely express what you mean as you enter your search.
But currently when you search in Google's knowledge graph, it shows you up to five related people, books, albums, movies and so on. If you want more, no option. That's why Google is testing new Google’s Expandable Knowledge Graph Test.In which, Google is adding an “explore more” more link that gives you a lot more related topics to scroll through right at the top of the page.
At the moment, a lot of searches don’t have answers from Knowledge Graph or other sources, so instead you get a conspicuously large amount of white space on the right side of the screen. But if anything, the new design seems like foreshadowing. Knowledge Graph may not provide too many answers now, but Google is leaving plenty of room for it to do so in the future.
