⬇️Narrower Term

NEW

A term representing a more specific concept that stands below a given concept in a hierarchy.

DESCRIPTION

Narrower terms capture specialization, enabling drill-down to detailed concepts and precise retrieval. In SKOS, skos:narrower links a concept to its more specific children. Consistent narrower assignments improve precision and user navigation. Over-fragmentation can create unusable depth and confusion. Governance should define granularity, avoid cycles, and support balanced structures. Narrower relationships are essential in thesauri, taxonomies, and dimensional models.

ALTERNATIVE DEFINITIONS

W3C

The properties skos:broader and skos:narrower are used to represent hierarchical links between concepts.
