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).

Context triple: [PEP-II storage ring, operatedAt, SLAC linear accelerator injector]
  • A. SLAC linac chosen
    The SLAC linac is a long linear particle accelerator at the SLAC National Accelerator Laboratory, historically used for high-energy physics experiments and as the main accelerator before the construction of the Stanford Linear Collider.
  • 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. UNILAC linear accelerator
    The UNILAC linear accelerator is a heavy-ion accelerator at the GSI Helmholtz Centre used to produce and study high-energy ion beams for nuclear and atomic physics research.
  • 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. Stanford Linear Collider (SLC)
    The Stanford Linear Collider (SLC) was a pioneering electron–positron linear collider at SLAC that enabled precision studies of the Z boson and electroweak interactions.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.

Provenance (2 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.
