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: Ti:sapphire lasers | Statement: [chirped pulse amplification, relatedTo, Ti:sapphire lasers]
NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07
Target entity: Ti:sapphire lasers
Context triple: [chirped pulse amplification, relatedTo, Ti:sapphire lasers]
  • A. helium–neon laser
    The helium–neon laser is a type of gas laser, commonly emitting visible red light at 632.8 nm, widely used for alignment, holography, and educational demonstrations due to its stable, low-power coherent beam.
  • B. Lasers
    Lasers is Lupe Fiasco’s third studio album, known for its politically charged lyrics, pop-oriented production, and contentious relationship with both his label and core fanbase.
  • C. erbium-doped fiber amplifier
    An erbium-doped fiber amplifier is an optical device that boosts the strength of light signals in fiber-optic communication systems by using erbium ions in the fiber core to provide efficient, low-noise signal amplification.
  • D. Spectral Band Replication
    Spectral Band Replication is an audio coding enhancement technique that reconstructs high-frequency components from lower-frequency data to improve compression efficiency at low bitrates.
  • E. chirped pulse amplification
    Chirped pulse amplification is a laser technique that stretches, amplifies, and then recompresses ultrashort light pulses to achieve extremely high peak powers without damaging optical components.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
