How this entity was disambiguated

This entity first appeared as the object of triple T299586 — 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: APG III classification
Context triple: [APG IV system, revises, APG III classification]

A. APG IV system
The APG IV system is the fourth modern classification framework for flowering plants developed by the Angiosperm Phylogeny Group, widely used to organize angiosperm families based on molecular phylogenetic evidence.
B. Rosales
Rosales is an order of flowering plants that includes many familiar trees, shrubs, and herbs such as elms, roses, and nettles.
C. Sapindales
Sapindales is an order of flowering plants that includes economically and ecologically important trees and shrubs such as mangoes, citrus, maples, and cashews.
D. Universal Decimal Classification
Universal Decimal Classification is an international library classification system that organizes knowledge into a detailed, hierarchical numeric scheme used widely in libraries and information centers around the world.
E. Ranunculales
Ranunculales is an order of flowering plants that includes several families of mostly herbaceous species, many of which are known for their ornamental flowers and bioactive chemical compounds.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
