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).

  • A. M2 beam line
    M2 beam line is a high-energy particle beam facility at CERN’s Super Proton Synchrotron used to deliver intense hadron and muon beams for fixed-target experiments such as COMPASS.
  • B. CERN test beam lines
    CERN test beam lines are specialized experimental facilities that deliver controlled particle beams to test and calibrate detectors and other high-energy physics instrumentation.
  • C. 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protons for injection into the Proton Synchrotron Booster and the rest of the accelerator complex before being superseded by Linac4.
  • D. CERN AWAKE experiment beamline
    The CERN AWAKE experiment beamline is a dedicated facility at CERN that studies proton-driven plasma wakefield acceleration to develop next-generation high-gradient particle accelerators.
  • E. SPEAR3 synchrotron light source
    The SPEAR3 synchrotron light source is a third-generation storage-ring facility at SLAC that produces intense, highly focused X-ray beams for advanced materials and biological research.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
