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: Linac2 | Statement: [Linac4, replaces, Linac2]

Target entity: Linac2
Context triple: [Linac4, replaces, Linac2]
  • A. Linac4
    Linac4 is a linear accelerator at CERN that serves as the first stage of the proton acceleration chain for the Large Hadron Collider and other experiments.
  • B. 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.
  • C. Antiproton Decelerator
    The Antiproton Decelerator is a specialized CERN facility that slows down antiprotons to low energies for precision experiments in antimatter physics.
  • D. 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.
  • E. Super Proton Synchrotron
    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.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
