# Knowledge Graph A knowledge graph represents entities and the relationships among them as an explicit network. Nodes may be people, documents, concepts, organizations, events, or other addressable things; edges carry typed relationships and often provenance. Bryant's anydata and PeopleLinking work, the Obsidian wiki, and the lexical association systems all contain graph-shaped information. The term should not erase their differences: a document graph, social/entity graph, and lexical association graph have different node and edge semantics.
