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: Michelson rotating mirror experiments | Statement: [Fizeau experiment, followedBy, Michelson rotating mirror experiments]

NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07

Target entity: Michelson rotating mirror experiments
Context triple: [Fizeau experiment, followedBy, Michelson rotating mirror experiments]

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. 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.
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. Michelson interferometer
The Michelson interferometer is a precision optical instrument that splits and recombines light beams to measure extremely small differences in path length, widely used in fundamental physics experiments and metrology.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
