Google Knowledge Graph
The Google Knowledge Graph is a knowledge base used by Google and its services to enhance its search engine's results with information gathered from a variety of sources. The information is presented to users in an infobox next to the search results. These infoboxes were added to Google's search engine in May 2012, starting in the United States, with international expansion by the end of the year.[1] Google has referred to these infoboxes, which appear to the right (top on mobile) of search results, as "knowledge panels".[2]
The information covered by Google's Knowledge Graph grew quickly after launch, tripling its size within seven months (covering 570 million entities and 18 billion facts[3]). By mid-2016, Google reported that it held 70 billion facts[4] and answered "roughly one-third" of the 100 billion monthly searches they handled. By May 2020, this had grown to 500 billion facts on 5 billion entities.[5]
There is no official documentation of how the Google Knowledge Graph is implemented.[6] According to Google, its information is retrieved from many sources, including the CIA World Factbook, Wikidata, and Wikipedia.[1][7] It is used to answer direct spoken questions in Google Assistant[8][9] and Google Home voice queries.[10] It has been criticized for providing answers without source attribution or citation.[11] Google knowledge panel will update automatically based on the information available on the web and various other sources.[12]
