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: [Baksan Neutrino Observatory, hasFacility, Baksan Experiment on Sterile Transitions]
  • A. Main Injector Experiment for ν-A
    Main Injector Experiment for ν-A (MINERvA) is a high-precision neutrino-scattering experiment at Fermilab designed to study how neutrinos interact with various nuclear targets.
  • B. Homestake solar neutrino experiment
    The Homestake solar neutrino experiment was a pioneering underground radiochemical detector in South Dakota that first measured solar neutrinos and revealed the solar neutrino problem, leading to major advances in neutrino physics.
  • C. Daya Bay Reactor Neutrino Experiment
    The Daya Bay Reactor Neutrino Experiment is a major particle physics project in China that precisely measured the neutrino mixing angle θ₁₃ using antineutrinos from nuclear reactors, significantly advancing our understanding of neutrino oscillations.
  • D. Experimental test of parity conservation in beta decay
    Experimental test of parity conservation in beta decay is the landmark 1956–57 physics experiment led by Chien-Shiung Wu that demonstrated the violation of parity symmetry in weak interactions, overturning a fundamental assumption of particle physics.
  • E. experiments at the Sudbury Neutrino Observatory
    Experiments at the Sudbury Neutrino Observatory were groundbreaking studies of solar neutrinos that provided key evidence for neutrino oscillations and the existence of neutrino mass.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
