> A [[Knowledge base|knowledge base]] whose entities and relationships are represented as nodes and edges in a [[Graph|graph]], structured so the graph itself can be [[Query|queried]], [[Graph traversal|traversed]], or [[Reasoning|reasoned over]]. ^definition The graph itself becomes a queryable object: paths, neighbourhoods, reachability, and community structure are first-class operations. The specific shape (directed, typed, weighted, schema-bound or schema-on-read, fact-asserted or confidence-graded) is a design choice each implementation makes.
