How this entity was disambiguated
This entity first appeared as the object of triple T12733866 — 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: Indian Ocean plate boundary system Context triple: [Owen Fracture Zone, partOf, Indian Ocean plate boundary system]
-
A.
Pacific Plate boundary system
The Pacific Plate boundary system is the extensive network of tectonic plate margins encircling the Pacific Ocean, characterized by subduction zones, transform faults, and spreading centers that generate intense seismic and volcanic activity.
-
B.
Australia–Eurasia plate boundary
The Australia–Eurasia plate boundary is a major tectonic boundary where the Australian Plate converges with the Eurasian Plate, producing intense seismic activity, mountain building, and deep ocean trenches across regions such as Indonesia and the surrounding seas.
-
C.
North Atlantic plate boundary system
The North Atlantic plate boundary system is the complex tectonic zone where the North American, Eurasian, and related plates interact through mid-ocean ridges, fracture zones, and transform faults across the North Atlantic Ocean.
-
D.
African–Eurasian plate boundary zone
The African–Eurasian plate boundary zone is a complex tectonic region where the African and Eurasian plates interact, giving rise to significant seismic and volcanic activity across parts of Europe, North Africa, and the Mediterranean.
-
E.
Indonesia–Australia plate boundary zone
The Indonesia–Australia plate boundary zone is a complex tectonic region where the Indo-Australian Plate interacts with the Eurasian and Pacific-related plates, producing intense seismicity, subduction, and mountain-building across eastern Indonesia and northern Australia.
- 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: Indian Ocean plate boundary system Description of subject: The Indian Ocean plate boundary system is the complex network of tectonic plate boundaries, including ridges, trenches, and fracture zones, that governs the seismic and volcanic activity across the Indian Ocean basin.
