How this entity was disambiguated
This entity first appeared as the object of triple T8788260 — 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.

gpt-5-mini-2025-08-07
Target entity: Southwest Pacific tectonic system Context triple: [New Guinea Trench, partOf, Southwest Pacific tectonic system]
-
A.
East Pacific tectonic system
The East Pacific tectonic system is a major geological region in the eastern Pacific Ocean characterized by active seafloor spreading, transform faults, and subduction zones that shape the surrounding oceanic plates and continental margins.
-
B.
Tonga-Kermadec subduction system
The Tonga-Kermadec subduction system is a major convergent plate boundary in the southwest Pacific where the Pacific Plate descends beneath the Indo-Australian Plate, producing one of the world’s deepest ocean trenches and most active seismic and volcanic regions.
-
C.
Sunda subduction system
The Sunda subduction system is a major convergent plate boundary in Southeast Asia where the Indo-Australian Plate is being subducted beneath the Eurasian/Sunda Plate, generating intense seismic and volcanic activity along Indonesia’s island arcs.
-
D.
Pacific Plate fracture zone system
The Pacific Plate fracture zone system is a network of major undersea tectonic fractures and transform faults that segment and shape the Pacific Plate across the ocean floor.
-
E.
Banda Sea subduction system
The Banda Sea subduction system is a complex convergent plate boundary in eastern Indonesia where oceanic lithosphere descends beneath surrounding plates, generating intense seismicity, volcanism, and intricate arc-continent collision structures.
- 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: Southwest Pacific tectonic system Description of subject: The Southwest Pacific tectonic system is a complex network of interacting tectonic plates, subduction zones, trenches, and volcanic arcs that shapes the geologic and seismic activity of the southwest Pacific region.
