How this entity was disambiguated

This entity first appeared as the object of triple T1299049 — 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.

NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07

Target entity: Filchner-Ronne Ice Shelf
Context triple: [Weddell Sea, hasIceShelf, Filchner-Ronne Ice Shelf]

A. Ross Ice Shelf
The Ross Ice Shelf is the world’s largest ice shelf, a vast floating extension of the Antarctic ice sheet that plays a key role in buttressing inland glaciers and influencing global sea-level stability.
B. Weddell Sea
The Weddell Sea is a large, ice-covered marginal sea off Antarctica known for its massive ice shelves, dense cold waters, and role in global ocean circulation.
C. Amundsen Sea
The Amundsen Sea is a remote, ice-covered marginal sea off the coast of West Antarctica, known for its rapidly thinning ice shelves and significant contribution to global sea-level rise.
D. Ross Sea
The Ross Sea is a deep bay of the Southern Ocean off Antarctica, renowned for its largely untouched marine ecosystem and rich biodiversity.
E. West Antarctica
West Antarctica is the portion of the Antarctic continent lying mostly west of the Transantarctic Mountains, known for its marine-based ice sheet that is particularly vulnerable to climate change and potential sea-level rise.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
