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

Target entity: Hubble constant Context triple: [cosmic microwave background, encodesInformationAbout, Hubble constant]
-
A.
Hubble constant H₀
chosen
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.
-
B.
Lemaître–Hubble law
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.
-
C.
Lambda-CDM model
The Lambda-CDM model is the standard cosmological framework describing a universe dominated by dark energy (Λ) and cold dark matter (CDM), successfully explaining the large-scale structure, expansion history, and cosmic microwave background observations.
-
D.
Milne universe model
The Milne universe model is a cosmological model that describes an empty, expanding universe with negative spatial curvature, serving as a special-relativistic alternative to general relativistic cosmologies.
-
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.
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.
