Named-entity recognition

Before disambiguation, gpt-5-mini classified whether the object phrase is a named entity — the step behind the object's NE type shown above.

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: UA1 experiment | Statement: [proton–antiproton collider at CERN, hostedExperiment, UA1 experiment]

Context triple: [proton–antiproton collider at CERN, hostedExperiment, UA1 experiment]
  • A. UA1 experiment chosen
    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. ATRAP experiment
    The ATRAP experiment is a particle physics project at CERN dedicated to trapping and studying antihydrogen atoms and other antimatter systems to test fundamental symmetries and the properties of antimatter.
  • D. ALPHA experiment
    The ALPHA experiment is a CERN-based research project that studies antihydrogen atoms to test fundamental symmetries between matter and antimatter.
  • E. PUMA experiment
    The PUMA experiment is a physics research project that studies the properties and interactions of antiprotons and antimatter using low-energy antiproton beams.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
