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: Isotope Separator On-Line Device | Statement: [ISOLDE, fullName, Isotope Separator On-Line Device]

Target entity: Isotope Separator On-Line Device
Context triple: [ISOLDE, fullName, Isotope Separator On-Line Device]
  • A. Oppenheimer–Phillips process
    The Oppenheimer–Phillips process is a nuclear reaction mechanism in which a deuteron interacting with a target nucleus effectively transfers its neutron while the proton is repelled, enabling certain reactions to occur at lower energies than would otherwise be required.
  • B. Antiproton Decelerator
    The Antiproton Decelerator is a specialized CERN facility that slows down antiprotons to low energies for precision experiments in antimatter physics.
  • C. Chicago Pile-1
    Chicago Pile-1 was the world’s first artificial nuclear reactor, achieving the first controlled, self-sustaining nuclear chain reaction in 1942 under the leadership of Enrico Fermi.
  • 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. K-West Reactor
    K-West Reactor is one of the plutonium production reactors at the Hanford Site in Washington State, historically used to support the U.S. nuclear weapons program.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
NEDg Description generation gpt-5.1
