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–Meyer function
Context triple: [Ludwig Prandtl, notableFor, Prandtl–Meyer function]
  • A. Joukowski airfoil
    The Joukowski airfoil is a mathematically defined airfoil shape derived using conformal mapping, foundational in early aerodynamic theory and airfoil design.
  • B. Mach number
    Mach number is a dimensionless quantity in fluid dynamics and aerodynamics that expresses the ratio of an object's speed to the local speed of sound, commonly used to characterize subsonic, transonic, supersonic, and hypersonic flows.
  • C. Blasius
    Blasius is a Latinized form of the given name Blaise, historically associated with Christian saints and scholars.
  • D. Mach cone
    A Mach cone is the conical shock wave pattern produced by an object traveling through a medium at a speed faster than the speed of sound.
  • E. Joukowski transform
    The Joukowski transform is a complex-plane mapping used in aerodynamics and fluid dynamics to model and analyze the flow around airfoils and other shapes.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
