To convert a grammar to Chomsky normal form, a sequence of simple transformations is applied in a certain order; this is described in most textbooks on automata theory. [4]: 87–94 [5] [6] [7] The presentation here follows Hopcroft, Ullman (1979), but is adapted to use the transformation names from Lange, Leiß (2009).
Context-free languages—or rather its subset of deterministic context-free languages—are the theoretical basis for the phrase structure of most programming languages, though their syntax also includes context-sensitive name resolution due to declarations and scope. Often a subset of grammars is used to make parsing easier, such as by an LL ...
Proving that this is the best of all possible worlds would dispel such charges by showing that, no matter how it may intuitively appear to us from our limited point of view, any other world – such as, namely, one without the evils which trouble our lives – would, in fact, have been worse than the current one, all things considered.

Firth is noted for drawing attention to the context-dependent nature of meaning with his notion of 'context of situation', and his work on collocational meaning is widely acknowledged in the field of distributional semantics. In particular, he is known for the famous quotation: You shall know a word by the company it keeps (Firth, J. R. 1957:11 ...
First, one must build a computational theory of the problem (i.e. the abstract formulation of the "what" and "why" of the problem). And then one must construct an algorithm that implements it (i.e. the "how" of the problem). Marr likened the computational theory of an information processing problem to the notion of "competence" mentioned in ...

Contextualism in epistemology then is a semantic thesis about how 'knows' works in English, not a theory of what knowledge, justification, or strength of epistemic position consists in. [7] However, epistemologists combine contextualism with views about what knowledge is to address epistemological puzzles and issues, such as skepticism, the ...
