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).

Target entity: Poincaré half-plane model
Context triple: [Non-Euclidean geometry, hasModel, Poincaré half-plane model]
  • A. Poincaré upper half-plane model chosen
    The Poincaré upper half-plane model is a standard representation of the hyperbolic plane using the complex numbers with positive imaginary part, equipped with a specific metric that makes geodesics appear as semicircles and vertical lines.
  • B. Poincaré disk model
    The Poincaré disk model is a representation of hyperbolic geometry in which the entire infinite hyperbolic plane is mapped inside a unit disk, with geodesics appearing as circular arcs orthogonal to the boundary.
  • C. Beltrami–Klein model
    The Beltrami–Klein model is a projective representation of hyperbolic geometry in which the entire hyperbolic plane is mapped inside a disk and geodesics appear as straight line segments.
  • D. Poincaré metric
    The Poincaré metric is the canonical complete Riemannian metric of constant negative curvature on simply connected Riemann surfaces like the unit disk or upper half-plane, fundamental in complex analysis and hyperbolic geometry.
  • E. Riemann sphere
    The Riemann sphere is the complex plane plus a point at infinity, forming a one-dimensional complex manifold topologically equivalent to a sphere and used to study meromorphic functions and complex analysis.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.

Provenance (3 batches)

The batch behind each pipeline step, in order, with when it ran. Timestamps are batch-level — stages were processed in waves, so the object chain (NER → NED1 → NEDg → NED2) reads in order, but predicate / elicitation batches can sit in a different wave.
