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: Fermi surface Context triple: [Fermi gas, relatedToConcept, Fermi surface]
-
A.
Fermi surface
chosen
The Fermi surface is the boundary in momentum space separating occupied from unoccupied electron states at zero temperature, crucial for determining a metal’s electronic and superconducting properties.
-
B.
Brillouin zone
The Brillouin zone is the fundamental region of reciprocal space in a crystal lattice, defining the allowed wavevectors for electrons and underpinning the structure of electronic band diagrams.
-
C.
Fermi energy
Fermi energy is the highest occupied energy level of a system of fermions at absolute zero temperature, playing a central role in determining the electronic and thermal properties of metals and semiconductors.
-
D.
Shubnikov–de Haas effect
The Shubnikov–de Haas effect is a quantum oscillatory phenomenon in the electrical resistance of conductors and semiconductors subjected to strong magnetic fields at low temperatures, used to probe their electronic structure and Fermi surface.
-
E.
Fermi gas
A Fermi gas is a quantum many-particle system composed of fermions that obey Fermi–Dirac statistics, often used to model electrons in metals, neutrons in neutron stars, and ultracold atomic gases.
- 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.
