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: Universal Polar Stereographic system | Statement: [UTM coordinate system, relatedSystem, Universal Polar Stereographic system]

Target entity: Universal Polar Stereographic system
Context triple: [UTM coordinate system, relatedSystem, Universal Polar Stereographic system]
  • 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. Transverse Mercator
    Transverse Mercator is a widely used map projection that represents the Earth’s surface on a cylinder aligned along a meridian, providing accurate large-scale mapping in narrow north–south zones.
  • 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. UTM coordinate system
    The UTM coordinate system is a global map projection and grid-based referencing system that divides the Earth into numbered zones to provide precise, metric-based location coordinates.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
