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: Stanford Positron Electron Asymmetric Ring (SPEAR)
Context triple: [SLAC National Accelerator Laboratory, hasFacility, Stanford Positron Electron Asymmetric Ring (SPEAR)]
  • A. 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.
  • 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. 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. 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. SPEAR3 synchrotron light source chosen
    The SPEAR3 synchrotron light source is a third-generation storage-ring facility at SLAC that produces intense, highly focused X-ray beams for advanced materials and biological research.
  • 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.
