Definition

A Knowledge Graph represents entities, concepts, attributes, and relationships as connected knowledge rather than isolated records.

Background

The term overlaps the Semantic Web lineage of RDF/OWL and the applied graph representations used in search, recommendation, and enterprise data integration.

Position

Ontology supplies the semantic design, RDF/OWL provide standards, Graphiti is a temporal implementation example, and RAG is an adjacent retrieval-generation pattern.

Distinctions

  • A graph database is storage and query infrastructure; a Knowledge Graph is a semantically interpreted knowledge structure.
  • The meaning of nodes and edges matters more than the visual graph shape.
