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: Rayleigh–Bénard convection | Statement: [Schwarzschild criterion, relatedTo, Rayleigh–Bénard convection]

Target entity: Rayleigh–Bénard convection
Context triple: [Schwarzschild criterion, relatedTo, Rayleigh–Bénard convection]
  • A. Rayleigh–Taylor instability
    Rayleigh–Taylor instability is a fluid dynamics phenomenon in which the interface between two fluids of different densities becomes unstable when the lighter fluid pushes against the heavier one, leading to complex mixing patterns.
  • B. Saffman–Taylor instability
    The Saffman–Taylor instability is a fluid dynamics phenomenon in which a less viscous fluid penetrating a more viscous one in a confined geometry leads to finger-like interfacial patterns, often called viscous fingering.
  • C. An Introduction to Fluid Dynamics
    An Introduction to Fluid Dynamics is a classic graduate-level textbook that rigorously develops the theoretical foundations of fluid mechanics and has become a standard reference in the field.
  • D. Kraichnan model of passive scalar advection
    The Kraichnan model of passive scalar advection is a theoretical framework in turbulence that studies how a passively transported quantity (like temperature or pollutant concentration) evolves in a fluid flow modeled by a Gaussian, white-in-time random velocity field.
  • E. Dynamics of Nonhomogeneous Fluids
    Dynamics of Nonhomogeneous Fluids is a seminal scientific monograph by Chia-Shun Yih that develops the theoretical foundations of fluid motion in media with spatially varying density and related properties.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
