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).

-
A.
On the theories of the internal friction of fluids in motion
"On the theories of the internal friction of fluids in motion" is a foundational scientific paper by George Gabriel Stokes that established key principles of fluid dynamics and viscosity, leading to what is now known as the Navier–Stokes equations.
-
B.
Blasius
Blasius is a Latinized form of the given name Blaise, historically associated with Christian saints and scholars.
-
C.
Stokes hypothesis in fluid mechanics
The Stokes hypothesis in fluid mechanics is an assumption relating the bulk viscosity of a Newtonian fluid to its shear viscosity, simplifying the constitutive equations used to model viscous flows.
-
D.
Perturbation Methods in Fluid Mechanics
Perturbation Methods in Fluid Mechanics is a classic graduate-level text that systematically develops asymptotic and perturbation techniques for analyzing complex fluid flow problems.
-
E.
On the Motion of Small Particles Suspended in Liquids at Rest Required by the Molecular-Kinetic Theory of Heat
"On the Motion of Small Particles Suspended in Liquids at Rest Required by the Molecular-Kinetic Theory of Heat" is Albert Einstein’s 1905 paper that provided a theoretical explanation of Brownian motion, offering strong evidence for the existence of atoms and molecules.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
