The Knowledge Graph is a knowledge base used by Google to enhance its search engine’s understanding of the world and provide more relevant and informative search results to users. It contains structured data about a wide range of topics, including people, places, events, and concepts, sourced from various reputable and authoritative sources such as Wikipedia, Freebase, and Google’s own data. The Knowledge Graph powers features such as knowledge panels, which appear alongside search results and provide quick answers and information about specific entities, and knowledge cards, which provide detailed information about topics such as movies, books, and landmarks.
