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: Fermat's principle
Context triple: [brachistochrone problem, relatedConcept, Fermat's principle]
  • A. Fermat’s principle of least time chosen
    Fermat’s principle of least time is a fundamental variational principle in optics stating that light follows the path that takes the least time, from which many laws of geometrical optics can be derived.
  • B. Snell’s law of refraction
    Snell’s law of refraction is a fundamental principle in optics that relates the angles of incidence and refraction to the refractive indices of two media, governing how light bends when passing between them.
  • C. Huygens–Fresnel principle
    The Huygens–Fresnel principle is a fundamental concept in wave optics that explains how every point on a wavefront acts as a source of secondary wavelets whose interference determines the wave’s subsequent propagation and diffraction.
  • D. Fresnel
    Fresnel is a surname most famously associated with Augustin-Jean Fresnel, the French physicist whose pioneering work on wave optics and the Fresnel lens revolutionized the understanding and application of light.
  • E. Babinet's principle
    Babinet's principle is a fundamental concept in wave optics stating that the diffraction pattern from an opaque object is identical to that from a complementary aperture of the same shape, apart from the overall intensity.
  • 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.
