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: CERN accelerator complex infrastructure | Statement: [CMS surface assembly hall, partOf, CERN accelerator complex infrastructure]

  • A. CERN Large Hadron Collider surface facilities
    The CERN Large Hadron Collider surface facilities are the above-ground buildings and infrastructure that support and control the LHC’s particle physics experiments near Geneva.
  • B. CERN accelerator complex chosen
    The CERN accelerator complex is a network of interconnected particle accelerators and beamlines near Geneva that produce and prepare high-energy particle beams for experiments such as those at the Large Hadron Collider.
  • C. LHC detector R&D
    LHC detector R&D is the program of research and development focused on designing, testing, and improving particle detectors for experiments at the Large Hadron Collider.
  • 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. 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.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
