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: Hubble constant H₀ | Statement: [Lemaître–Hubble law, hasParameter, Hubble constant H₀]

Target entity: Hubble constant H₀
Context triple: [Lemaître–Hubble law, hasParameter, Hubble constant H₀]
  • A. 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.
  • B. 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.
  • C. 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.
  • D. 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.
  • E. The Big Bang
    The Big Bang is the climactic Series 5 finale of the British science-fiction television show Doctor Who, featuring the Eleventh Doctor in a time-bending resolution to the season’s overarching storyline.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
