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).

Target entity: Fermilab Booster synchrotron
Context triple: [Booster Neutrino Beam, usesAccelerator, Fermilab Booster synchrotron]
  • A. Fermilab Booster chosen
    Fermilab Booster is a rapid-cycling synchrotron at Fermilab that accelerates protons to intermediate energies before sending them to higher-energy accelerators and experiments.
  • B. 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.
  • C. Fermilab Linac
    Fermilab Linac is a linear accelerator at Fermilab that provides high-energy proton beams for subsequent acceleration stages in the laboratory’s particle physics experiments.
  • D. Antiproton Accumulator
    The Antiproton Accumulator was a storage and cooling ring at CERN designed to collect, cool, and accumulate antiprotons for high-energy proton–antiproton collision experiments.
  • E. 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.
  • 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.
