How this entity was disambiguated
This entity first appeared as the object of triple T5686926 — 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: Galápagos Transform Fault system Context triple: [Galápagos Spreading Center, linkedTo, Galápagos Transform Fault system]
-
A.
Galápagos Spreading Center
The Galápagos Spreading Center is a mid-ocean ridge segment in the eastern Pacific where tectonic plates diverge and new oceanic crust forms near the Galápagos Islands.
-
B.
Cocos–Nazca spreading center
The Cocos–Nazca spreading center is a mid-ocean ridge in the eastern Pacific where tectonic divergence forms and separates the Cocos and Nazca plates.
-
C.
East Pacific Rise
The East Pacific Rise is a major mid-oceanic ridge and seafloor spreading center in the eastern Pacific Ocean, where tectonic plates diverge and new oceanic crust is formed.
-
D.
Romanche transform fault
The Romanche transform fault is a major east–west striking fracture zone and transform fault in the equatorial Atlantic Ocean that offsets the Mid-Atlantic Ridge and hosts one of the deepest points in the Atlantic.
-
E.
Juan de Fuca Ridge
Juan de Fuca Ridge is an underwater volcanic spreading center in the northeastern Pacific Ocean where new oceanic crust forms as tectonic plates diverge.
- 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: Galápagos Transform Fault system Description of subject: The Galápagos Transform Fault system is a series of major strike-slip faults in the eastern Pacific that offset and segment the Galápagos Spreading Center, influencing regional plate motions and seafloor morphology.
