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: Doppler effect | Statement: [Ives–Stilwell experiment, category, Doppler effect]

gpt-5-mini-2025-08-07
Target entity: Doppler effect Context triple: [Ives–Stilwell experiment, category, Doppler effect]
-
A.
Zeeman effect
The Zeeman effect is the splitting of atomic or molecular spectral lines into multiple components when subjected to an external magnetic field, revealing information about energy levels and magnetic moments.
-
B.
Hertzian waves
Hertzian waves are early experimentally demonstrated electromagnetic waves that confirmed James Clerk Maxwell’s theory of electromagnetism and paved the way for modern radio communication.
-
C.
Tolman–Ehrenfest effect
The Tolman–Ehrenfest effect is a relativistic thermodynamic phenomenon stating that, in a system at thermal equilibrium within a gravitational field, temperature varies with gravitational potential so that hotter regions occur deeper in the gravitational well.
-
D.
Kapitza–Dirac effect
The Kapitza–Dirac effect is a quantum phenomenon in which a beam of particles, such as electrons or atoms, is diffracted by a standing wave of light, demonstrating the wave-particle duality of matter.
-
E.
Unruh effect
The Unruh effect is a predicted phenomenon in quantum field theory where an accelerating observer perceives what inertial observers consider vacuum as a warm bath of particles with a characteristic temperature.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
NEDg
Description generation
gpt-5.1
Instruction
Generate a one-sentence description of the target entity. You are given a context triple in the form (subject, predicate, object), where the object is the target entity. # Instructions Use the triple to infer relevant information about the entity. Describe the entity based on what is most defining, well-known. Avoid repeating the information from the triple, unless really essential. # Response Format Return only the sentence: "Description: [one-sentence description of the target entity]"
Input
Entity: Doppler effect Triple: [Ives–Stilwell experiment, category, Doppler effect]
Generated description
The Doppler effect is the change in frequency or wavelength of a wave perceived by an observer moving relative to the source of the wave, commonly experienced with sound and electromagnetic waves.
