NER Named-entity recognition gpt-5-mini
Instruction
Given a phrase, classify it is english named entity (e.g., persons, organizations, works of art) in Latin script, or not (e.g., literals, dates, URLs, verbose phrases). For disambiguation, the statement where the phrase occurs as object is also given. Please return a JSON object with `phrase` (string, the phrase being analyzed) and `is_ne` (boolean, indicating whether the phrase is a Named Entity).
Input
Phrase: Transverse Mercator | Statement: [Ordnance Survey National Grid, projection, Transverse Mercator]
NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07 
Target entity: Transverse Mercator
Context triple: [Ordnance Survey National Grid, projection, Transverse Mercator]
  • A. Lambert conformal conic projection
    The Lambert conformal conic projection is a map projection that preserves local shapes and angles, commonly used for aeronautical charts and regional maps in mid-latitude areas.
  • B. Irish Transverse Mercator
    Irish Transverse Mercator is a modern, high-precision map projection and coordinate reference system used for surveying and mapping across Ireland.
  • C. Mercator projection
    The Mercator projection is a cylindrical map projection widely used for navigation because it preserves angles and directions but greatly distorts the size of landmasses near the poles.
  • D. Lambert azimuthal equal-area projection
    The Lambert azimuthal equal-area projection is a map projection that preserves area while representing the Earth on a circular, azimuthally symmetric plane, commonly used for mapping continents and polar regions.
  • E. WGS84
    WGS84 is the global geodetic reference system and standard coordinate framework used for GPS and most modern mapping applications.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
