How this entity was disambiguated

This entity first appeared as the object of triple T10414200 — 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: hydraulic economic computer MONIAC
Context triple: [A. W. Phillips, developed, hydraulic economic computer MONIAC]

A. Klein–Tinbergen macroeconometric models
The Klein–Tinbergen macroeconometric models are pioneering large-scale quantitative models of national economies that integrated economic theory with statistical estimation to analyze and forecast macroeconomic activity.
B. Colossus computers
Colossus computers were pioneering British electronic computing machines built during World War II to help decrypt high-level German communications at Bletchley Park.
C. Harvard Mark IV computer
The Harvard Mark IV computer was an early fully electronic, stored-program computer built at Harvard University in the late 1940s–early 1950s as part of the Mark series of pioneering computing machines.
D. Harvard Mark III computer
The Harvard Mark III computer was an early electromechanical/digital hybrid computer developed in the late 1940s that advanced stored-program concepts and military computation at Harvard University.
E. Modigliani–Brumberg model
The Modigliani–Brumberg model is an economic life-cycle theory explaining how individuals plan consumption and saving over their lifetimes to smooth living standards despite changing income.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
