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).

NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07
Target entity: redshift–distance relation
Context triple: [A Relation between Distance and Radial Velocity among Extra-Galactic Nebulae, relatedConcept, redshift–distance relation]
  • A. Tully-Fisher relation distances
    Tully-Fisher relation distances are galaxy distance measurements derived from the empirical correlation between a spiral galaxy’s luminosity and its rotational velocity.
  • B. 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.
  • C. A Relation between Distance and Radial Velocity among Extra-Galactic Nebulae
    "A Relation between Distance and Radial Velocity among Extra-Galactic Nebulae" is Edwin Hubble’s landmark 1929 paper that established the linear relationship between galaxies’ distances and their recessional velocities, providing the first strong evidence for the expanding universe.
  • D. Faber–Jackson relation
    The Faber–Jackson relation is an empirical correlation in astronomy that links the luminosity of an elliptical galaxy to the velocity dispersion of its stars, providing a key tool for estimating galactic distances and masses.
  • E. Sachs–Wolfe effect
    The Sachs–Wolfe effect is a cosmological phenomenon in which gravitational potential fluctuations imprint temperature anisotropies on the cosmic microwave background radiation, especially on large angular scales.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
