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: Franck–Hertz experiment | Statement: [James Franck, notableWork, Franck–Hertz experiment]

Target entity: Franck–Hertz experiment
Context triple: [James Franck, notableWork, Franck–Hertz experiment]
  • A. Davisson–Germer experiment
    The Davisson–Germer experiment was a landmark 1927 physics experiment that demonstrated the wave nature of electrons through diffraction from a nickel crystal, providing key evidence for quantum mechanics and wave–particle duality.
  • B. Trouton–Noble experiment
    The Trouton–Noble experiment was an early 20th-century test of the luminiferous aether that searched for a torque on a charged capacitor in motion and, by finding no such effect, provided support for the emerging theory of special relativity.
  • C. Cockcroft–Walton experiment
    The Cockcroft–Walton experiment was a pioneering 1932 nuclear physics experiment that achieved the first artificial disintegration of atomic nuclei using accelerated protons, confirming Einstein’s mass–energy equivalence.
  • D. Ives–Stilwell experiment
    The Ives–Stilwell experiment is a classic test of special relativity that measured the relativistic Doppler effect to confirm time dilation for fast-moving ions.
  • E. Michelson–Morley experiment
    The Michelson–Morley experiment was a landmark 1887 physics experiment that attempted to detect the Earth's motion through the hypothesized luminiferous aether and whose null result helped pave the way for Einstein's theory of special relativity.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
