Than a context-free grammar.
Not all languages can be generated by context-free grammars.
Context-free languages not closed under complementation.
Properties of context-free languages.
The context-free languages are not closed under intersection.
There exist context-sensitive languages which are not context-free.
The context-free language class is not closed under intersection.
Chomsky subsequently reinterpreted these as operations on the productions of a context-free grammar(derived from Post production systems).
All regular, context-free and context-sensitive languages are recursive.
Approaches which have been used include straightforward PCFGs(probabilistic context-free grammars), maximum entropy, and neural nets.
Context-free languages are not closed under complement, intersection, or difference.
Languages can be shown to be non-context-free using the Pumping Lemma for context-free languages.
Context-free grammars are limited in the extent to which they can express all of the requirements of a language.
To prove that a given language is not context-free, one employs the pumping lemma for context-free languages.
Context-free grammars are limited in the extent to which they can express all of the requirements of a language.
In general, even if the desired structure is not context-free, some kind of context-free approximation to the grammar is used to perform a first pass.
Context-free grammars(Context-free languages are those that can be defined by context-free grammars.).
In the 1960s, theoretical research in computer science on regular expressions andfinite automata led to the discovery that context-free grammars are equivalent to nondeterministic pushdown automata.
A formal language is context-free if a contextfree grammar generates it.
In 1953, he founded a pioneering algebraic-computational linguistic group, and in 1961 he contributed to the proof of the pumping lemma for context-free languages(sometimes called the Bar-Hillel lemma).
The formalism of context-free grammars was developed in the mid-1950s by Noam Chomsky.
The class of indexed languages has practical importance in natural language processing as a computationally affordable generalization of context-free languages, since indexed grammars can describe many of the nonlocal constraints occurring in natural languages.
All regular, context-free, context-sensitive and recursive languages are recursively enumerable.
The addition of the empty string allows the statement that the context sensitive languages are a proper superset of the context-free languages, rather than having to make the weaker statement that all context-free grammars with no→λ productions are also context sensitive grammars.
All regular, context-free, context-sensitive and recursive languages are recursively enumerable.
Every regular language is context-free because it can be described by a regular grammar.
A context-free grammar for the language consisting of all strings over{a, b} containing an unequal number of a's and b's.
The intersection of a context-free language anda regular language is always context-free.
A context-free grammar is a grammar in which the left-hand side of each production rule consists of only a single non-terminal symbol.
Most programming languages are context-free languages, allowing them to be parsed with stack based machines.
