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).

Context triple: [Fizeau experiment, relatedTo, Fizeau–Foucault experiment]
  • A. Fizeau experiment
    The Fizeau experiment was a pioneering 19th-century physics experiment that measured the speed of light using a rotating toothed wheel and helped establish light’s finite velocity.
  • B. 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.
  • C. Eötvös experiment
    The Eötvös experiment is a classic physics test of the equivalence principle that measures whether different materials fall with the same acceleration in a gravitational field.
  • D. Michelson rotating mirror experiments
    Michelson rotating mirror experiments were precision optical measurements conducted by Albert A. Michelson to determine the speed of light using rapidly spinning mirrors and long-distance light paths.
  • E. 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.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
