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: BASE experiment | Statement: [Antiproton Decelerator, providesBeamTo, BASE experiment]
NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07
Target entity: BASE experiment
Context triple: [Antiproton Decelerator, providesBeamTo, BASE experiment]
  • A. UA1 experiment
    The UA1 experiment was a high-energy physics collaboration at CERN’s Super Proton Synchrotron that became famous for providing the first experimental evidence of the W and Z bosons, key carriers of the weak nuclear force.
  • B. UA2 experiment
    The UA2 experiment was a high-energy physics collaboration at CERN’s Super Proton Synchrotron that played a key role in confirming the existence and properties of the W boson.
  • 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. 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.
