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: Kelvin–Helmholtz instability Context triple: [Rayleigh–Taylor instability, relatedTo, Kelvin–Helmholtz instability]
-
A.
Kelvin–Helmholtz instability
chosen
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.
-
B.
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.
-
C.
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.
-
D.
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.
-
E.
Kruskal–Shafranov instability criterion
The Kruskal–Shafranov instability criterion is a fundamental condition in plasma physics that predicts when a magnetically confined plasma column becomes unstable to kink-like distortions.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
Provenance (3 batches)
The batch behind each pipeline step, in order, with when it ran. Timestamps are batch-level — stages were processed in waves, so the object chain (NER → NED1 → NEDg → NED2) reads in order, but predicate / elicitation batches can sit in a different wave.
