Knowledge panel data about Thomas Jefferson displayed on Google Search, as of January 2015

The Google Knowledge Graph is a knowledge base from which Google serves relevant information in an infobox beside its search results. This allows the user to see the answer in a glance, as an instant answer. The data is generated automatically from a variety of sources, covering places, people, businesses, and more.[1][2]

The information covered by Google's Knowledge Graph grew quickly after launch, tripling its data 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 and Wikipedia.[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 with neither source attribution nor citations.[11]
