⬆️Broader Term

NEW

A term representing a more general concept that stands above a given concept in a hierarchy.

DESCRIPTION

Broader terms capture generalization relationships, enabling hierarchical navigation and retrieval expansion. In SKOS, skos:broader links a concept to its more general parent. Proper broader assignments improve browsing, recall, and roll-up analytics. Overusing broader links can dilute specificity; underuse hides meaningful context. Governance ensures consistent broader-narrower application and prevents cycles. Broader relationships are foundational in thesauri and taxonomies.

ALTERNATIVE DEFINITIONS
