2. Generalized context-free grammar - Wikipedia

   en.wikipedia.org/wiki/Generalized_context-free...

   Generalized context-free grammar (GCFG) is a grammar formalism that expands on context-free grammars by adding potentially non-context-free composition functions to rewrite rules. [1] Head grammar (and its weak equivalents) is an instance of such a GCFG which is known to be especially adept at handling a wide variety of non-CF properties of ...

3. LALR parser generator - Wikipedia

   en.wikipedia.org/wiki/LALR_parser_generator

   A lookahead LR parser (LALR) generator is a software tool that reads a context-free grammar (CFG) and creates an LALR parser which is capable of parsing files written in the context-free language defined by the CFG. LALR parsers are desirable because they are very fast and small in comparison to other types of parsers.

4. Comparison of parser generators - Wikipedia

   en.wikipedia.org/.../Comparison_of_parser_generators

   To do so technically would require a more sophisticated grammar, like a Chomsky Type 1 grammar, also termed a context-sensitive grammar. However, parser generators for context-free grammars often support the ability for user-written code to introduce limited amounts of context-sensitivity.

5. Context-free grammar - Wikipedia

   en.wikipedia.org/wiki/Context-free_grammar

   An extended context-free grammar (or regular right part grammar) is one in which the right-hand side of the production rules is allowed to be a regular expression over the grammar's terminals and nonterminals. Extended context-free grammars describe exactly the context-free languages.

6. Synchronous context-free grammar - Wikipedia

   en.wikipedia.org/wiki/Synchronous_context-free...

   Synchronous context-free grammars (SynCFG or SCFG; not to be confused with stochastic CFGs) are a type of formal grammar designed for use in transfer-based machine translation. Rules in these grammars apply to two languages at the same time, capturing grammatical structures that are each other's translations.

7. Lemon (parser generator) - Wikipedia

   en.wikipedia.org/wiki/Lemon_(parser_generator)

   Lemon is a parser generator, maintained as part of the SQLite project, that generates a look-ahead LR parser (LALR parser) in the programming language C from an input context-free grammar. The generator is quite simple, implemented in one C source file with another file used as a template for output. Lexical analysis is performed externally.

8. Quranic Arabic Corpus - Wikipedia

   en.wikipedia.org/wiki/Quranic_Arabic_Corpus

   Unlike other annotated Arabic corpora, the grammar framework adopted by the Quranic Corpus is the traditional Arabic grammar of i'rab (إﻋﺮﺍﺏ). The research project is led by Kais Dukes at the University of Leeds , [ 4 ] and is part of the Arabic language computing research group within the School of Computing, supervised by Eric Atwell.

9. Deterministic context-free grammar - Wikipedia

   en.wikipedia.org/wiki/Deterministic_context-free...

   Deterministic context-free grammars were particularly useful because they could be parsed sequentially by a deterministic pushdown automaton, which was a requirement due to computer memory constraints. [4] In 1965, Donald Knuth invented the LR(k) parser and proved that there exists an LR(k) grammar for every deterministic context-free language. [5]
