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: Hele–Shaw experiments | Statement: [Saffman–Taylor instability, studiedUsing, Hele–Shaw experiments]

-
A.
Hele–Shaw cell
chosen
A Hele–Shaw cell is a narrow, fluid-filled gap between two closely spaced plates used to study two-dimensional viscous flow and pattern-forming instabilities in fluid dynamics.
-
B.
Saffman–Taylor instability
The Saffman–Taylor instability is a fluid dynamics phenomenon in which a less viscous fluid penetrating a more viscous one in a confined geometry leads to finger-like interfacial patterns, often called viscous fingering.
-
C.
Rayleigh–Bénard convection
Rayleigh–Bénard convection is a fluid dynamics phenomenon in which a horizontal fluid layer heated from below develops organized convection cells due to buoyancy-driven instability.
-
D.
Taylor–Couette flow
Taylor–Couette flow is the fluid motion that arises between two concentric, independently rotating cylinders, notable for its rich pattern of instabilities and vortical structures that are fundamental in fluid dynamics research.
-
E.
On the theories of the internal friction of fluids in motion
"On the theories of the internal friction of fluids in motion" is a foundational scientific paper by George Gabriel Stokes that established key principles of fluid dynamics and viscosity, leading to what is now known as the Navier–Stokes equations.
- 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.
