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: Boltzmann–Kac equation | Statement: [Kac walk, relatedTo, Boltzmann–Kac equation]

Target entity: Boltzmann–Kac equation
Context triple: [Kac walk, relatedTo, Boltzmann–Kac equation]
  • A. Boltzmann equation
    The Boltzmann equation is a fundamental kinetic theory equation that describes the statistical behavior and time evolution of a dilute gas or particle distribution in phase space due to streaming and collisions.
  • B. Boltzmann–BGK equation
    The Boltzmann–BGK equation is a simplified kinetic model that replaces the complex collision term of the Boltzmann equation with a single relaxation-time approximation to describe gas particle dynamics.
  • C. Vlasov equation (for long-range interactions and negligible collisions)
    The Vlasov equation is a kinetic equation that describes the evolution of the distribution function of a many-particle system with long-range interactions in the collisionless (or weakly collisional) regime, widely used in plasma physics and astrophysics.
  • D. Fokker–Planck equation
    The Fokker–Planck equation is a partial differential equation that describes the time evolution of the probability density function of a stochastic (random) process, such as Brownian motion.
  • E. Boltzmann collision operator
    The Boltzmann collision operator is the nonlinear integral term in kinetic theory that models how particle collisions change the distribution of molecular velocities in a gas.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
