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

NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07 
Target entity: cobalt-60 beta decay parity violation experiment
Context triple: [Wu experiment, alsoKnownAs, cobalt-60 beta decay parity violation experiment]
  • A. Experimental test of parity conservation in beta decay chosen
    Experimental test of parity conservation in beta decay is the landmark 1956–57 physics experiment led by Chien-Shiung Wu that demonstrated the violation of parity symmetry in weak interactions, overturning a fundamental assumption of particle physics.
  • B. Cowan–Reines neutrino experiment
    The Cowan–Reines neutrino experiment was the first successful detection of neutrinos, providing direct experimental confirmation of their existence and validating key aspects of weak interaction theory.
  • C. Fermi theory of beta decay
    The Fermi theory of beta decay is Enrico Fermi’s pioneering quantum field theory model that explains beta decay as a weak interaction process mediated by a four-fermion contact interaction, laying the groundwork for modern weak interaction theory.
  • D. Wu experiment
    The Wu experiment was a landmark 1956 nuclear physics experiment that demonstrated the violation of parity conservation in weak interactions, fundamentally reshaping our understanding of fundamental symmetries in nature.
  • E. DIRAC experiment
    The DIRAC experiment is a high-energy physics project at CERN designed to study pionium (a bound state of a π⁺ and π⁻ meson) to test predictions of low-energy quantum chromodynamics.
  • 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.
