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).

gpt-5-mini-2025-08-07
Target entity: Hubble’s law Context triple: [Hubble–Humason galaxy redshift measurements, refined, Hubble’s law]
-
A.
Lemaître–Hubble law
chosen
The Lemaître–Hubble law is the fundamental cosmological relation that expresses the proportionality between a galaxy’s recessional velocity and its distance, providing the first observational evidence for the expansion of the universe.
-
B.
Hubble constant H₀
The Hubble constant H₀ is the cosmological parameter that quantifies the present-day rate at which the universe is expanding, relating galaxies’ recession velocities to their distances.
-
C.
Slipher galaxy redshift measurements
Slipher galaxy redshift measurements are early 20th-century spectroscopic observations by Vesto Slipher that first revealed significant radial velocities of spiral nebulae, laying crucial groundwork for the discovery of the expanding universe.
-
D.
Hubble time
Hubble time is the estimated age of the universe derived from the rate of its expansion as described by the Hubble constant.
-
E.
The Expanding Universe
"The Expanding Universe" is a chapter in Stephen Hawking’s popular science book *A Brief History of Time* that explains how observations and cosmological theory reveal that the universe is growing larger over time.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
