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 North Area experimental infrastructure | Statement: [T4 beam line, partOf, CERN North Area experimental infrastructure]

  • B. CERN data centre
    The CERN data centre is the primary computing and data storage facility of the European Organization for Nuclear Research, handling the massive data output from experiments like those at the Large Hadron Collider.
  • C. CERN Experimental Areas group
    The CERN Experimental Areas group is a team at CERN responsible for managing and supporting the operation of its fixed-target and test-beam experimental facilities.
  • 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
    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.
  • F. None of above.
