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: H0LiCOW collaboration | Statement: [Hubble constant, isConstrainedBy, H0LiCOW collaboration]

Target entity: H0LiCOW collaboration
Context triple: [Hubble constant, isConstrainedBy, H0LiCOW collaboration]
  • A. Supernova Cosmology Project
    The Supernova Cosmology Project is an international research collaboration that used observations of distant Type Ia supernovae to discover the accelerating expansion of the universe, providing key evidence for dark energy.
  • B. Recalibration of the Hubble constant
    Recalibration of the Hubble constant is a landmark astrophysical study by Allan R. Sandage that refined the value of the universe’s expansion rate using improved distance measurements to galaxies.
  • C. 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.
  • D. Hubble–Humason galaxy redshift measurements
    The Hubble–Humason galaxy redshift measurements are a landmark set of observations that extended and refined Edwin Hubble’s work on the expanding universe by systematically measuring the redshifts of distant galaxies.
  • E. Planck Collaboration
    The Planck Collaboration is an international team of scientists responsible for operating the Planck space telescope and analyzing its data to study the cosmic microwave background and the early universe.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
