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: Super Proton Synchrotron | Statement: [proton–antiproton collider at CERN, builtInTunnelOf, Super Proton Synchrotron]

NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07 
Target entity: Super Proton Synchrotron
Context triple: [proton–antiproton collider at CERN, builtInTunnelOf, Super Proton Synchrotron]
  • A. Super Proton Synchrotron chosen
    The Super Proton Synchrotron is a high-energy circular particle accelerator at CERN that serves both as a research machine and as a key injector for the Large Hadron Collider.
  • B. Proton Synchrotron
    The Proton Synchrotron is a historic circular particle accelerator at CERN that has played a key role in high-energy physics research and in feeding beams to larger colliders.
  • C. Proton Synchrotron Booster
    The Proton Synchrotron Booster is a circular particle accelerator at CERN that increases the energy of protons from the linear accelerator before injecting them into larger synchrotrons in the accelerator complex.
  • D. CERN accelerator complex
    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.
  • 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.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.

  • B. tunnels
    Indicates that one entity passes through, under, or within another entity via a tunnel-like passage or structure.
  • C. isOriginalTunnelOf
    Indicates that one tunnel is the initial or primary tunnel from which another tunnel is derived, duplicated, or modified.
  • D. isInTunnelSystem
    Indicates that one entity is located within or forms part of a tunnel system associated with another entity.
  • E. usesTunnel
    Indicates that one entity makes use of a tunnel as a passage or route to reach or connect to another entity.
  • F. None of above.
