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).

Context triple: [LDSS-2, fullName, Low Dispersion Survey Spectrograph 2]
  • A. Low Dispersion Survey Spectrograph 3
    Low Dispersion Survey Spectrograph 3 is an astronomical instrument used on large telescopes to obtain low-resolution spectra of many celestial objects simultaneously for survey and follow-up observations.
  • B. FOcal Reducer and low dispersion Spectrograph 2
    FOcal Reducer and low dispersion Spectrograph 2 (FORS2) is a versatile optical instrument on ESO’s Very Large Telescope used for imaging, polarimetry, and low-resolution spectroscopy of astronomical objects.
  • C. DEIMOS spectrograph
    The DEIMOS spectrograph is a powerful multi-object optical spectrograph designed for wide-field, high-resolution spectroscopy of faint astronomical sources.
  • D. Coudé Echelle Spectrometer
    Coudé Echelle Spectrometer is a high-resolution astronomical spectrograph designed for detailed analysis of stellar and other celestial spectra, typically fed by a telescope’s coudé focus.
  • E. Faint Object Spectrograph
    The Faint Object Spectrograph was an early-generation Hubble Space Telescope instrument designed to obtain detailed spectra of very dim astronomical objects across a wide range of wavelengths.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
