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

Target entity: Balbus–Hawley instability
Context triple: [Steven Balbus, knownFor, Balbus–Hawley instability]
  • A. Holmboe instability
    Holmboe instability is a type of shear-driven wave instability that occurs in stably stratified fluids, producing characteristic interfacial waves and mixing at density interfaces.
  • B. Kelvin–Helmholtz instability
    Kelvin–Helmholtz instability is a fluid dynamical phenomenon in which velocity shear between layers of fluid (or plasma) with different densities leads to characteristic wave-like billows and turbulent mixing at their interface.
  • C. Jeans instability
    Jeans instability is a gravitational phenomenon in astrophysics where regions within a gas cloud become unstable and collapse under their own gravity, leading to the formation of structures like stars and galaxies.
  • D. Chandrasekhar–Friedman–Schutz instability
    The Chandrasekhar–Friedman–Schutz instability is a gravitational-radiation-driven instability in rotating stars that can cause certain oscillation modes to grow by emitting gravitational waves.
  • E. Rayleigh–Taylor instability
    Rayleigh–Taylor instability is a fluid dynamics phenomenon in which the interface between two fluids of different densities becomes unstable when the lighter fluid pushes against the heavier one, leading to complex mixing patterns.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
