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: [Linac4, relatedProject, LHC Injectors Upgrade (LIU)]
  • A. LHC injector chain
    The LHC injector chain is the sequence of accelerators and beamlines at CERN that progressively boost and prepare particle beams before they are injected into the Large Hadron Collider.
  • B. Linac4
    Linac4 is a linear accelerator at CERN that serves as the first stage of the proton acceleration chain for the Large Hadron Collider and other experiments.
  • C. High-Luminosity LHC
    The High-Luminosity LHC is a major upgrade of CERN’s Large Hadron Collider designed to significantly increase its collision rate and data output for more precise and rare particle physics measurements.
  • D. Linac2
    Linac2 was CERN’s long-serving linear accelerator that pre-accelerated protons for injection into the Proton Synchrotron Booster and the rest of the accelerator complex before being superseded by Linac4.
  • E. Large Hadron Collider
    The Large Hadron Collider is the world’s largest and most powerful particle accelerator, used to smash subatomic particles together at unprecedented energies to study fundamental physics, including the Higgs boson.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
