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
Phrase: Weyl connection | Statement: [Weyl geometry, hasKeyConcept, Weyl connection]

Target entity: Weyl connection
Context triple: [Weyl geometry, hasKeyConcept, Weyl connection]
  • A. Weyl geometry
    Weyl geometry is a generalization of Riemannian geometry that allows the length of vectors to vary under parallel transport, forming the geometric framework for Weyl’s original gauge theory.
  • B. Levi-Civita connection
    The Levi-Civita connection is the unique torsion-free affine connection on a Riemannian manifold that is compatible with its metric, enabling the definition of parallel transport and covariant differentiation.
  • C. Ehresmann connection
    An Ehresmann connection is a geometric structure on a fiber bundle that specifies a way to consistently split tangent spaces into vertical and horizontal parts, enabling the definition of parallel transport.
  • D. Cartan connections
    Cartan connections are a geometric framework generalizing affine and Riemannian connections that model curved spaces on homogeneous spaces, developed by Élie Cartan.
  • E. Weyl tensor
    The Weyl tensor is the traceless part of the Riemann curvature tensor in differential geometry and general relativity, encoding the purely shape-distorting (conformal) aspects of spacetime curvature independent of matter content.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
