How this entity was disambiguated
This entity first appeared as the object of triple T3142073 — 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.

Indian Ocean Ridge system
The Indian Ocean Ridge system is a vast mid-ocean ridge network in the Indian Ocean where tectonic plates diverge and new oceanic crust is formed.
-
D.
Southeast Indian Ridge
The Southeast Indian Ridge is a major mid-ocean spreading center in the southern Indian Ocean that forms part of the global system of divergent tectonic plate boundaries.
-
E.
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.

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: Atlantic–Antarctic Ridge system Description of subject: The Atlantic–Antarctic Ridge system is a major mid-ocean ridge complex in the South Atlantic and Southern Ocean where tectonic plates diverge and new oceanic crust is formed.
