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: [Gary W. Gibbons, notableConcept, Gibbons–Hawking–York boundary term in gravitational action]
  • A. Gibbons–Hawking–York boundary term chosen
    The Gibbons–Hawking–York boundary term is an additional term in the gravitational action of general relativity that ensures a well-defined variational principle in spacetimes with boundaries.
  • B. Einstein–Hilbert action
    The Einstein–Hilbert action is the fundamental action in general relativity whose variation yields Einstein’s field equations, expressing gravity as the dynamics of spacetime curvature.
  • C. Euclidean quantum gravity
    Euclidean quantum gravity is an approach to quantum gravity that reformulates general relativity in imaginary (Euclidean) time to define a path integral over geometries, often used in black hole thermodynamics and early-universe cosmology.
  • D. Plebański formulation of self-dual gravity
    The Plebański formulation of self-dual gravity is a reformulation of general relativity that expresses gravity as a self-dual gauge theory using differential forms, providing a powerful framework for studying classical and quantum aspects of spacetime.
  • E. Bondi–Metzner–Sachs symmetry
    Bondi–Metzner–Sachs symmetry is an infinite-dimensional group of asymptotic spacetime symmetries in general relativity that characterizes the gravitational field at null infinity, especially in the context of gravitational radiation.
  • 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.
