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).

  • A. DEEP2 Redshift Survey
    The DEEP2 Redshift Survey is a large astronomical project that mapped the distant universe by measuring precise redshifts of tens of thousands of galaxies to study their evolution and large-scale structure.
  • B. CfA Redshift Survey
    The CfA Redshift Survey is a pioneering large-scale galaxy redshift survey that mapped the three-dimensional distribution of galaxies in the nearby universe, revealing major structures such as superclusters and voids.
  • C. IRAS redshift survey
    The IRAS redshift survey is a large-scale astronomical mapping project that used data from the Infrared Astronomical Satellite to chart the three-dimensional distribution of galaxies in the nearby universe.
  • D. Deep Extragalactic Survey
    Deep Extragalactic Survey is a deep near-infrared astronomical survey within the UKIDSS project designed to study distant galaxies and the large-scale structure of the universe.
