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: Ekman layer | Statement: [Ekman transport, occursIn, Ekman layer]
NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07
Target entity: Ekman layer
Context triple: [Ekman transport, occursIn, Ekman layer]
  • A. Ekman transport
    Ekman transport is an oceanographic process in which wind-driven surface waters move at an angle to the wind direction due to the Coriolis effect, causing net water transport perpendicular to the wind.
  • B. Saffman
    Saffman is a surname most notably associated with Philip G. Saffman, a prominent British-American applied mathematician and fluid dynamicist.
  • C. Bjerknes compensation
    Bjerknes compensation is a climate science concept describing how changes in ocean heat transport tend to be offset by opposite changes in atmospheric heat transport, helping stabilize the total poleward energy flux.
  • D. Beaufort Gyre
    The Beaufort Gyre is a large, wind-driven ocean circulation system in the Arctic Ocean that traps and stores vast amounts of sea ice and freshwater.
  • E. Coriolis effect
    The Coriolis effect is the apparent deflection of moving objects caused by Earth's rotation, strongly influencing global wind patterns and ocean currents.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
