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

Target entity: Antiproton Decelerator at CERN
Context triple: [BASE experiment, locatedAt, Antiproton Decelerator at CERN]
  • A. Antiproton Decelerator chosen
    The Antiproton Decelerator is a specialized CERN facility that slows down antiprotons to low energies for precision experiments in antimatter physics.
  • B. Antihydrogen Laser Physics Apparatus
    Antihydrogen Laser Physics Apparatus is a CERN-based experiment designed to produce, trap, and study antihydrogen atoms with lasers to test fundamental symmetries between matter and antimatter.
  • C. proton–antiproton collider at CERN
    The proton–antiproton collider at CERN was a high-energy particle accelerator complex that enabled the discovery of the W and Z bosons, confirming the electroweak theory of the Standard Model.
  • D. Brookhaven Linac Isotope Producer
    The Brookhaven Linac Isotope Producer is a particle-accelerator-based facility at Brookhaven National Laboratory that generates medical and research isotopes for nuclear medicine and scientific applications.
  • E. SPS Heavy Ion and Neutrino Experiment
    The SPS Heavy Ion and Neutrino Experiment (NA61/SHINE) is a fixed-target particle physics experiment at CERN’s Super Proton Synchrotron that studies hadron production in proton, pion, and ion collisions for strong-interaction physics and neutrino beam characterization.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.

Provenance (3 batches)

The batch behind each pipeline step, in order, with when it ran. Timestamps are batch-level — stages were processed in waves, so the object chain (NER → NED1 → NEDg → NED2) reads in order, but predicate / elicitation batches can sit in a different wave.
