How this entity was disambiguated
This entity first appeared as the object of triple T11958195 — 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.

Target entity: Yacc Context triple: [GNU Bison, basedOn, Yacc]
-
A.
GNU Bison
GNU Bison is a widely used parser generator that converts context-free grammars into C-based parsers, commonly employed in compilers and interpreters within the GNU ecosystem.
-
B.
GNU Flex
GNU Flex is a widely used open-source lexical analyzer generator that produces C-based scanners for tokenizing text according to user-defined patterns.
-
C.
javacc
JavaCC is a popular open-source parser generator for Java that allows developers to define grammars and automatically produce parsers.
-
D.
Van Wijngaarden grammars
Van Wijngaarden grammars are a highly expressive formal grammar formalism, introduced for defining complex programming language syntax and semantics, notably used in the specification of ALGOL 68.
-
E.
Backus–Naur Form
Backus–Naur Form is a formal notation used to define the syntax of programming languages and other formal grammars in a precise, structured way.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
