Knowledge Graph Knowledge Graph The web of entities engines use to reason.

A knowledge graph is a structured database of entities and the relationships between them. Google's Knowledge Graph powers the right-rail panel and underpins entity disambiguation across Search and AI Overviews. LLMs build implicit knowledge graphs from training data; explicit graphs (Wikidata, schema.org markup) help them ground answers.
