Named-entity recognition

Before disambiguation, gpt-5-mini classified whether the object phrase is a named entity — the step behind the object's NE type shown above.

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: Hubble constant H0 | Statement: [Lambda-CDM model, parameterizedBy, Hubble constant H0]

NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07 
Target entity: Hubble constant H0
Context triple: [Lambda-CDM model, parameterizedBy, Hubble constant H0]
  • 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. 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.
  • E. steady-state cosmology
    Steady-state cosmology is a now largely discredited cosmological model proposing an eternal, unchanging universe in which new matter is continuously created to maintain constant density despite expansion.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
