How this entity was disambiguated
This entity first appeared as the object of triple T111018 — 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.
Target entity: Juan de Fuca Ridge Context triple: [Juan de Fuca Plate, createdAt, Juan de Fuca Ridge]
-
A.
Juan de Fuca Plate
The Juan de Fuca Plate is a small oceanic tectonic plate off the Pacific Northwest coast whose subduction beneath North America drives significant volcanic and seismic activity in the region.
-
B.
Romanche Fracture Zone
The Romanche Fracture Zone is a major transform fault and deep-sea fracture zone in the equatorial Atlantic Ocean that offsets the Mid-Atlantic Ridge and hosts one of the deepest points in the Atlantic basin.
-
C.
Southwest Indian Ridge
The Southwest Indian Ridge is a slow-spreading mid-ocean ridge in the southern Indian Ocean that forms part of the global system of divergent tectonic plate boundaries.
-
D.
Mid-Atlantic Ridge
The Mid-Atlantic Ridge is a vast underwater mountain range and divergent tectonic plate boundary running down the center of the Atlantic Ocean, where new oceanic crust is formed.
-
E.
Aleutian Arc
The Aleutian Arc is a major volcanic island chain and subduction zone stretching from Alaska toward Russia, forming part of the tectonically active northern boundary of the Pacific Ocean.
- 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.
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.
