A Knowledge Graph is a structured database of real-world entities (people, places, organizations, concepts) and their semantic interrelationships maintained by search engines and AI models.

Powers Google Knowledge Panels and supplies baseline entity facts that LLMs consult during training and RAG retrieval.

Analogy & Mental Model

A Knowledge Graph is like a giant interconnected mind map connecting every famous person, company, and concept in the world with labeled relationship lines.

Relationship Linking
