What is the Knowledge Graph made up of?

In 2012, Google added an expansion of search results with a widget on entities in the Knowledge Graph. In the Knowledge Graph people, places or the circumstances of various facts, images and associated search queries are displayed in a dedicated area if Google recognizes or suspects a semantic entity behind a search term. The information leveraged by the Knowledge Graph used to partially come from Freebase, whereas today it is mainly gathered from Wikidata, enriched with enhancing links or related search terms .

On desktops and tablets the Knowledge Graph is displayed on the right next to the organic search results; on smartphones the display is above the search results. The following elements can be included in the separate info box:

  • Data on a company, a person or a location
  • Image(s) with a link to Google Image Search
  • Text extract as well as a link to the source
  • Prepared, structured data with details on the search query
  • Information on similar search queries “others also searched for”

Which sources does the Knowledge Graph use?
