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: Davisson–Germer experiment | Statement: [Davisson–Germer Prize in Atomic or Surface Physics, namedForDiscovery, Davisson–Germer experiment]
NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07
Target entity: Davisson–Germer experiment
Context triple: [Davisson–Germer Prize in Atomic or Surface Physics, namedForDiscovery, Davisson–Germer experiment]
  • A. 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.
  • 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. 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.
  • D. Kennedy–Thorndike experiment
    The Kennedy–Thorndike experiment is a classic test of special relativity that examined the constancy of the speed of light using an interferometer with unequal arm lengths and varying laboratory velocity.
  • E. Cavendish experiment
    The Cavendish experiment was an 18th-century physics experiment by Henry Cavendish that measured the tiny gravitational attraction between lead spheres, allowing the first calculation of the gravitational constant and the mass of the Earth.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
