Knowledge graph
Also: knowledge graphs
A map of things and how they connect, such as people, companies, and events, with lines between them.
The fuller definition
A knowledge graph represents entities and relationships explicitly, often as nodes and labelled connections.
- Person
Morgan
- Relationship
Sent
- Document
Email A03
A simplified relationship, not a screenshot or a complete design.
A concrete example
A matter graph links a person to an email they sent and that email to the document it attaches.
The distinction that matters
