Context (linguistics) In semiotics, linguistics, sociology and anthropology, context refers to those objects or entities which surround a focal event, in these disciplines typically a communicative event, of some kind. Context is "a frame that surrounds the event and provides resources for its appropriate interpretation".
Context-free grammar. Simplified excerpt of the formal grammar [1] for the C programming language (left), and a derivation of a piece of C code (right) from the nonterminal symbol . Nonterminal symbols are blue and terminal symbols are red. In formal language theory, a context-free grammar ( CFG) is a formal grammar whose production rules can ...
96 million monthly active users (June 2019) [1] Reverso is a French company specialized in AI-based language tools, translation aids, and language services. [2] These include online translation based on neural machine translation (NMT), contextual dictionaries, online bilingual concordances, grammar and spell checking and conjugation tools.
Context-free language. In formal language theory, a context-free language ( CFL ), also called a Chomsky type-2 language, is a language generated by a context-free grammar (CFG). Context-free languages have many applications in programming languages, in particular, most arithmetic expressions are generated by context-free grammars.
A context menu (also called contextual, shortcut, and pop up or pop-up menu) is a menu in a graphical user interface (GUI) that appears upon user interaction, such as a right-click mouse operation. A context menu offers a limited set of choices that are available in the current state, or context, of the operating system or application to which ...
Computational properties. Computationally, a context-sensitive language is equivalent to a linear bounded nondeterministic Turing machine, also called a linear bounded automaton.
In computer science, in particular in formal language theory, the pumping lemma for context-free languages, also known as the Bar-Hillel lemma, [1] is a lemma that gives a property shared by all context-free languages and generalizes the pumping lemma for regular languages . The pumping lemma can be used to construct a proof by contradiction ...
ConTeXt is a general-purpose document processor. Like LaTeX, it is derived from TeX. It is especially suited for structured documents, automated document production, very fine typography, and multilingual typesetting. It is based in part on the TeX typesetting system, and uses a document markup language for manuscript preparation.
