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: Prandtl–Taylor vortices
Context triple: [Ludwig Prandtl, notableFor, Prandtl–Taylor vortices]
  • A. Taylor–Proudman theorem
    The Taylor–Proudman theorem is a fundamental result in geophysical fluid dynamics stating that in a rapidly rotating, inviscid, incompressible fluid, steady flows tend to be uniform along the axis of rotation, leading to columnar motion.
  • B. Taylor–Couette flow
    Taylor–Couette flow is the fluid motion that arises between two concentric, independently rotating cylinders, notable for its rich pattern of instabilities and vortical structures that are fundamental in fluid dynamics research.
  • C. The Structure of Turbulent Shear Flow
    The Structure of Turbulent Shear Flow is a foundational scholarly work in fluid mechanics that analyzes the behavior, organization, and modeling of turbulence in shear flows.
  • D. Rayleigh–Bénard convection
    Rayleigh–Bénard convection is a fluid dynamics phenomenon in which a horizontal fluid layer heated from below develops organized convection cells due to buoyancy-driven instability.
  • E. Taylor microscale in turbulence
    The Taylor microscale in turbulence is a characteristic length scale that quantifies the size of eddies where viscous dissipation begins to significantly affect turbulent motion, bridging the gap between large energy-containing eddies and the smallest dissipative scales.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
