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: Introduction to Aerodynamics of a Compressible Fluid | Statement: [Hans W. Liepmann, authorOf, Introduction to Aerodynamics of a Compressible Fluid]

Target entity: Introduction to Aerodynamics of a Compressible Fluid
Context triple: [Hans W. Liepmann, authorOf, Introduction to Aerodynamics of a Compressible Fluid]
  • A. 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.
  • B. Prandtl lifting-line theory
    Prandtl lifting-line theory is a foundational aerodynamic model that predicts the lift distribution and induced drag of finite wings by representing them as bound vortices along a lifting line.
  • C. Fluid Mechanics: A Concise Introduction to the Theory
    "Fluid Mechanics: A Concise Introduction to the Theory" is a foundational textbook by Chia-Shun Yih that presents the core principles and mathematical framework of fluid mechanics in a compact, rigorous form.
  • D. Mathematical Theory of Compressible Fluid Flow
    Mathematical Theory of Compressible Fluid Flow is a foundational work in fluid mechanics that systematically develops the mathematics governing gases and liquids whose density changes significantly under pressure, with applications to aerodynamics and high-speed flows.
  • E. Prandtl mixing length theory
    Prandtl mixing length theory is a foundational turbulence model in fluid mechanics that describes how momentum is transported in turbulent flows using an analogy to molecular diffusion, introducing a characteristic mixing length scale.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
