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.
NEDg
Description generation
gpt-5.1
Instruction
Generate a one-sentence description of the target entity. You are given a context triple in the form (subject, predicate, object), where the object is the target entity. # Instructions Use the triple to infer relevant information about the entity. Describe the entity based on what is most defining, well-known. Avoid repeating the information from the triple, unless really essential. # Response Format Return only the sentence: "Description: [one-sentence description of the target entity]"
Input
