A structured representation of entities and their relationships, enabling machines to understand and reason about real-world concepts. Knowledge graphs enable structured reasoning and relationship inference. They are often used alongside language models to improve contextual understanding. For more on AI system architectures, see our systems analysis.
Knowledge graphs provide structured, verified information that can ground AI responses and reduce hallucinations.
Some AI systems query knowledge graphs during response generation to verify facts and retrieve structured information about entities.
Knowledge graphs help AI systems understand that a company and its CEO are related entities.
