context-free

context-free

Said of a grammar where the syntax of each constituent is independent of the symbols occuring before and after it in a sentence. Parsers for such grammars are simpler than those for context-dependent grammars because the parser need only know the current symbol.

Second, Specificity versus Generality, in which the need for broadly applicable, context-free or at least context-agnostic approaches to teacher preparation (generality) is in tension with the significant role that specific contexts play in the development of effective teaching practices (specificity).
But since when are you supposed to be context-free in the MCU?
The two rounds featured problems about Gilbertese, Northern and Central Pame, Albanian, Palauan, Vietnamese, the N'ko script, Menya, Chalcatongo Mixtec, Sinhalese, Nivkh, Fijian, Tamil, Beja, as well as more computational problems such as synchronic context-free grammars and tokenization, semantic ambiguities, phonological assimilation, and shift-reduce parsers.
It was the American development (1844), which made it possible to publish the large circulation daily newspaper by moving decontextualised information from all over the world and thereby created what is called 'The News of the Day.' Postman argues 'telegraph gave a form of legitimacy to the idea of context-free information; that is, to the idea that the value of information need not be tied to any function that it might serve in social and political decision-making and action, but may attach merely to its novelty, interest, and curiosity...most of our daily news is insert, consisting of information that gives us something to talk about but cannot lead to any meaningful action.' The Pulitzer Prize is the most prestigious prize for a journalist in the US today.
On the other hand, the rule-base is assumed to be context-free and is usually valid in any context, as the context of use affects only the meaning associated with each linguistic term used in the rules rather than the logic of the rules themselves [8, 10].
This sequence included working with diagrams in the following sequential settings: contextual whole number division settings, context-free whole number division settings, contextual fraction division settings, and context-free fraction division settings (refer Figure 2 for samples from each setting/class).
Chapter 7 enriches the somewhat context-free models in the previous chapter by unfolding information behavior in organizations.
Still another aspect of meaning would come to mind had you read,"Dan jumped up, howling in pain." The meaning of"spill" depends on context, but dictionaries, including internet dictionaries, necessarily offer context-free meanings.

Moreover, terminologies like Context-free Grammar (CFG) and Definite Clause Grammar (DCG) are also discussed.
The grammar we use is a context-free grammar in Backus Naur form that contains all elements necessary to build a basic fuzzy rule learner, following the fuzzy set covering paradigm.
This both sharpens and generalises Brandstadt's result that if L is context-free then [C.sup.k] (L) is context-sensitive and not context-free in general for k [greater than or equal to] 3.
