How this entity was disambiguated
This entity first appeared as the object of triple T6579983 — 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: Pacific equatorial current system Context triple: [New Guinea Coastal Undercurrent, isPartOf, Pacific equatorial current system]
-
A.
North Pacific western boundary current system
The North Pacific western boundary current system is a major ocean circulation feature comprising strong poleward and subpolar currents along the western edge of the North Pacific that play a key role in regional climate, heat transport, and marine ecosystems.
-
B.
Equatorial Countercurrent
The Equatorial Countercurrent is an eastward-flowing ocean current found near the equator that runs between the westward-flowing North and South Equatorial Currents in the world’s major oceans.
-
C.
New Guinea Coastal Undercurrent
The New Guinea Coastal Undercurrent is a subsurface ocean current that flows westward along the northern coast of New Guinea, playing a key role in redistributing heat and salt within the tropical Pacific.
-
D.
North Equatorial Current (regional)
The North Equatorial Current (regional) is a major westward-flowing ocean current in the Pacific that influences circulation, climate, and deep-sea conditions around features such as the Mariana Trench.
-
E.
Subtropical Countercurrent
The Subtropical Countercurrent is an eastward-flowing ocean current in the North Pacific that runs opposite to the prevailing trade-wind-driven currents within the subtropical gyre.
- 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
