How this entity was disambiguated

This entity first appeared as the object of triple T9810119 — 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: Isar proof language
Context triple: [Isabelle/HOL: A Proof Assistant for Higher-Order Logic, describes, Isar proof language]

A. Isabelle proof assistant
Isabelle proof assistant is a widely used interactive theorem prover and generic proof assistant designed for formal verification and mathematical logic, particularly known for its support of higher-order logic.
B. Isabelle/HOL: A Proof Assistant for Higher-Order Logic
"Isabelle/HOL: A Proof Assistant for Higher-Order Logic" is a foundational book and system documentation that presents the Isabelle/HOL interactive theorem prover, widely used for formal verification and higher-order logic reasoning in computer science and mathematics.
C. LCF theorem prover
The LCF theorem prover is an early interactive proof system that pioneered the use of higher-order logic and the LCF-style architecture, forming the conceptual basis for later provers like HOL and Isabelle.
D. HOL theorem prover
The HOL theorem prover is an interactive proof assistant for higher-order logic, widely used in formal verification of hardware, software, and mathematical theories.
E. Boyer–Moore theorem prover
The Boyer–Moore theorem prover is an influential automated reasoning system for first-order logic and recursive function theory, notable for pioneering techniques in mechanical proof and program verification.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
