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 | Statement: [A Relation between Distance and Radial Velocity among Extra-Galactic Nebulae, relatesTo, Hubble constant]

NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07 
Target entity: Hubble constant
Context triple: [A Relation between Distance and Radial Velocity among Extra-Galactic Nebulae, relatesTo, 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.
