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: Fermilab Main Injector | Statement: [Fermilab Booster, feeds, Fermilab Main Injector]
NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07
Target entity: Fermilab Main Injector
Context triple: [Fermilab Booster, feeds, Fermilab Main Injector]
  • A. Fermilab Booster
    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. 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.
  • 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. 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. Tevatron
    Tevatron was a circular particle accelerator at Fermilab that for many years was the world’s highest-energy collider, crucial in advancing high-energy physics research.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
