How this entity was disambiguated
This entity first appeared as the object of triple T1362933 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

Entity disambiguation (via context triple)
gpt-5-mini-2025-08-07
Target entity: Coriolis effect Context triple: [South Equatorial Current, governedBy, Coriolis effect]
-
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.
Earth rotation
Earth rotation is the spinning of our planet on its axis, which produces the cycle of day and night and underlies the measurement of time.
-
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.
Faraday effect
The Faraday effect is a magneto-optical phenomenon in which the polarization plane of light is rotated as it passes through a material under the influence of a magnetic field aligned with the direction of propagation.
-
E.
Southern Oscillation
The Southern Oscillation is a large-scale atmospheric pressure pattern across the tropical Pacific that drives the El Niño–Southern Oscillation climate phenomenon and influences global weather and rainfall.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
Input
Subject: Coriolis effect Description of subject: The Coriolis effect is the apparent deflection of moving objects caused by Earth's rotation, strongly influencing global wind patterns and ocean currents.
