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: Euler equations of fluid motion | Statement: [Bernoulli equation, relatedConcept, Euler equations of fluid motion]

Target entity: Euler equations of fluid motion
Context triple: [Bernoulli equation, relatedConcept, Euler equations of fluid motion]
  • A. Euler equations chosen
    The Euler equations are fundamental partial differential equations in fluid dynamics that describe the motion of an ideal (inviscid) fluid without viscosity.
  • B. Navier–Stokes equations
    The Navier–Stokes equations are fundamental partial differential equations in fluid mechanics that describe how the velocity field of a fluid evolves under forces like pressure and viscosity.
  • C. Euler–Poisson equations
    The Euler–Poisson equations are a system of differential equations in rigid body dynamics that describe the rotational motion of a rigid body with a fixed point under the influence of external forces such as gravity.
  • D. 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.
  • E. 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.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
