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).
Input
Phrase: LNGS underground halls | Statement: [OPERA, sitedIn, LNGS underground halls]

  • A. LHC service tunnels
    The LHC service tunnels are auxiliary underground passages at CERN that house infrastructure and provide access and support to the Large Hadron Collider’s main accelerator ring.
  • B. CMS experimental cavern
    The CMS experimental cavern is the large underground facility at CERN that houses the Compact Muon Solenoid detector for high-energy particle collision experiments at the Large Hadron Collider.
  • C. Sanford Underground Research Facility
    The Sanford Underground Research Facility is a deep underground laboratory in South Dakota that hosts major particle physics and astrophysics experiments, including serving as the far-site for the DUNE neutrino project.
  • D. CERN control centre
    The CERN Control Centre is the central facility from which scientists and engineers operate and monitor CERN’s particle accelerators and associated experiments.
  • E. CERN Large Hadron Collider surface facilities
