Named-entity recognition

Before disambiguation, gpt-5-mini classified whether the object phrase is a named entity — the step behind the object's NE type shown above.

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: Raman spectroscopy | Statement: [Raman effect, underlies, Raman spectroscopy]

NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07 
Target entity: Raman spectroscopy
Context triple: [Raman effect, underlies, Raman spectroscopy]
  • A. Raman effect chosen
    The Raman effect is a spectroscopic phenomenon in which light scattered by a material undergoes a change in wavelength due to interactions with the material’s molecular vibrations, providing a powerful tool for chemical and structural analysis.
  • B. Fourier transform infrared spectroscopy
    Fourier transform infrared spectroscopy is an analytical technique that measures how a sample absorbs infrared light across a wide range of wavelengths to determine its molecular composition and structure.
  • C. Laser Induced Breakdown Spectroscope
    Laser Induced Breakdown Spectroscope is a scientific instrument that analyzes the elemental composition of materials by focusing a high-energy laser to create a plasma and studying the emitted light spectrum.
  • D. Fourier transform spectrometer
    A Fourier transform spectrometer is an optical instrument that measures the spectrum of a light source by recording an interference pattern and mathematically transforming it to obtain high-resolution spectral information.
  • E. Grille spectrometer
    The Grille spectrometer is a spaceborne infrared spectrometer designed to study the composition and structure of planetary and Earth atmospheres by analyzing their emitted and absorbed radiation.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
