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: MINOS neutrino experiment | Statement: [Soudan Underground Mine State Park, hostedExperiment, MINOS neutrino experiment]

NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07 
Target entity: MINOS neutrino experiment
Context triple: [Soudan Underground Mine State Park, hostedExperiment, MINOS neutrino experiment]
  • A. MINOS experiment chosen
    The MINOS experiment is a long-baseline neutrino oscillation project that studied how neutrinos change type as they travel from Fermilab to a distant underground detector.
  • 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. LBNE experiment
    The LBNE (Long-Baseline Neutrino Experiment) was a proposed U.S.-based long-baseline neutrino physics project that laid the groundwork for what became the Deep Underground Neutrino Experiment (DUNE).
  • D. Fermilab Short-Baseline Neutrino Program
    The Fermilab Short-Baseline Neutrino Program is a suite of neutrino experiments at Fermilab designed to precisely study neutrino oscillations and search for evidence of sterile neutrinos over short distances.
  • E. NOvA experiment
    The NOvA experiment is a long-baseline neutrino oscillation project that studies how neutrinos change type as they travel from Fermilab to a distant detector in northern Minnesota.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
