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).

Target entity: C-weighting
Context triple: [Fletcher–Munson equal-loudness contours, basisFor, C-weighting]
  • A. B-weighting
    B-weighting is an audio frequency weighting curve derived from early equal-loudness contour research, used to approximate human hearing sensitivity at moderately high sound levels.
  • B. A-weighting
    A-weighting is a standard frequency weighting curve used in sound level measurements that approximates the human ear’s sensitivity to different frequencies, especially at moderate sound levels.
  • C. Fletcher–Munson equal-loudness contours
    The Fletcher–Munson equal-loudness contours are a set of curves that describe how the human ear’s sensitivity to sound varies with frequency and sound pressure level, forming the basis for understanding perceived loudness in acoustics and audio engineering.
  • D. Decibel
    "Decibel" is a hard rock song by Australian band AC/DC from their 2008 album *Black Ice*.
  • E. Robinson–Dadson equal-loudness contours
    Robinson–Dadson equal-loudness contours are a set of experimentally derived curves that describe how the human ear’s sensitivity to sound varies with frequency and level, providing an improved standard over earlier loudness contour data.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
NED2 Entity disambiguation (via description) gpt-5-mini-2025-08-07
