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).

NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07 
Target entity: Korteweg–de Vries equation
Context triple: [Clifford S. Gardner, studied, Korteweg–de Vries equation]
  • A. Korteweg–De Vries equation chosen
    The Korteweg–De Vries equation is a fundamental nonlinear partial differential equation that models shallow water waves and solitons, playing a central role in the theory of integrable systems.
  • B. Kadomtsev–Petviashvili equation
    The Kadomtsev–Petviashvili equation is a fundamental nonlinear partial differential equation in mathematical physics that generalizes the Korteweg–De Vries equation to two spatial dimensions to describe the evolution of weakly dispersive, weakly nonlinear waves.
  • C. Zur Theorie der nichtlinearen Wellen
    "Zur Theorie der nichtlinearen Wellen" is Klaus Hasselmann's doctoral thesis, a foundational work on the behavior and mathematical description of nonlinear waves in physics.
  • D. Painlevé–Kruskal theorem
    The Painlevé–Kruskal theorem is a result in the theory of nonlinear differential equations that characterizes integrability through the analytic structure of their solutions, particularly via the Painlevé property.
  • E. Liouville equation
    The Liouville equation is a fundamental differential equation in statistical mechanics and Hamiltonian dynamics that governs the time evolution of a system’s phase-space probability density.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
