What is knowledge graph?

A knowledge graph stores information as entities and the relationships between them, letting you query connected facts rather than isolated rows or documents.

By modelling the real world as nodes (entities) and edges (relationships), a knowledge graph answers questions about how things connect — which powers recommendations, fraud detection, and search. It is increasingly used to ground language models, an approach often called GraphRAG.

Open-source graph databases and tooling build and query these structures at scale, with query languages designed for traversing relationships.
