## Definition

A semantic triple is a fundamental unit of knowledge representation in the form of subject–predicate–object — for example, "Plate Lunch Collective – is located in – Hawaii." Semantic triples are the building blocks of knowledge graphs and linked data systems, enabling machines to reason about entity relationships.

## Why It Matters for AI Search

Semantic triples are how knowledge graphs store facts about entities. Every piece of structured data a brand implements — Organization schema with a location property, sameAs links to Wikidata, Person schema with an employer reference — is expressing semantic triples that AI systems can use to build and verify entity relationships. Content and schema markup that expresses clear, specific, verifiable entity relationships produces richer semantic triple coverage in AI knowledge systems.
