How this entity was disambiguated

This entity first appeared as the object of triple T1717900 — 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: Berkeley RISC projects
Context triple: [RISC-V, inspiredBy, Berkeley RISC projects]

A. Acorn RISC Machine
Acorn RISC Machine (ARM) is a family of energy-efficient reduced instruction set computer (RISC) architectures widely used in mobile devices, embedded systems, and increasingly in servers and personal computers.
B. SPARC microprocessor architecture
The SPARC microprocessor architecture is a RISC-based instruction set architecture widely used in high-performance and enterprise servers, originally created to power scalable, multi-processor systems.
C. UCSD p-System
UCSD p-System is a portable operating system and programming environment based on the Pascal language and p-code virtual machine, widely used in the late 1970s and early 1980s across multiple hardware platforms.
D. Project Oberon
Project Oberon is a computer system design and implementation project, including both an operating system and programming language, created by Swiss computer scientist Niklaus Wirth as a minimalist, modular, and educationally oriented computing environment.
E. UCSD Pascal
UCSD Pascal is a variant of the Pascal programming language designed for the UCSD p-System, notable for its portability and use in early microcomputer environments.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
