Named-entity recognition

Before disambiguation, gpt-5-mini classified whether the object phrase is a named entity — the step behind the object's NE type shown above.

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: Cabibbo–Kobayashi–Maskawa matrix | Statement: [Kobayashi–Maskawa paper on CP violation (1973), mainSubject, Cabibbo–Kobayashi–Maskawa matrix]

NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07 
Target entity: Cabibbo–Kobayashi–Maskawa matrix
Context triple: [Kobayashi–Maskawa paper on CP violation (1973), mainSubject, Cabibbo–Kobayashi–Maskawa matrix]
  • A. Cabibbo–Kobayashi–Maskawa matrix chosen
    The Cabibbo–Kobayashi–Maskawa matrix is a fundamental component of the Standard Model of particle physics that describes how quarks change flavor via the weak interaction and accounts for CP violation in the quark sector.
  • B. Kobayashi–Maskawa theory
    The Kobayashi–Maskawa theory is a fundamental framework in particle physics that explains CP violation in the Standard Model through a three-generation quark mixing matrix (the CKM matrix).
  • C. Cabibbo theory
    Cabibbo theory is a framework in particle physics that describes the mixing of down and strange quarks in weak interactions through a single mixing angle, laying groundwork later generalized by the CKM matrix.
  • D. Gell-Mann–Nishijima formula
    The Gell-Mann–Nishijima formula is a key relation in particle physics that connects a particle’s electric charge to its isospin and hypercharge, helping classify hadrons within the quark model.
  • E. Gell-Mann–Okubo mass formula
    The Gell-Mann–Okubo mass formula is a relation in particle physics that predicts the mass patterns of hadrons within SU(3) flavor symmetry multiplets, providing quantitative support for the quark model and the Eightfold Way classification.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
