The raw input, the 43 characters, must be explicitly split into the 9 tokens with a given space delimiter (i.e., matching the string " "or regular expression /\s{1}/). When a token class represents more than one possible lexeme, the lexer often saves enough information to reproduce the original lexeme, so that it can be used in semantic analysis.
String functions are used in computer programming languages to manipulate a string or query information about a string (some do both).. Most programming languages that have a string datatype will have some string functions although there may be other low-level ways within each language to handle strings directly.
Word segmentation is the problem of dividing a string of written language into its component words. In English and many other languages using some form of the Latin alphabet, the space is a good approximation of a word divider (word delimiter), although this concept has limits because of the variability with which languages emically regard collocations and compounds.
In linguistic morphology and information retrieval, stemming is the process of reducing inflected (or sometimes derived) words to their word stem, base or root form—generally a written word form. The stem need not be identical to the morphological root of the word; it is usually sufficient that related words map to the same stem, even if this ...
It is defined as the "shortest grammatically allowable sentences into which (writing can be split) or minimally terminable unit." Often, but not always, a T-unit is a sentence. More technically, a T-unit is a dominant clause and its dependent clauses: as Hunt said: it is "one main clause with all subordinate clauses attached to it" (Hunt 1965:20).
A string (or word [23] or expression [24]) over Σ is any finite sequence of symbols from Σ. [25] For example, if Σ = {0, 1}, then 01011 is a string over Σ. The length of a string s is the number of symbols in s (the length of the sequence) and can be any non-negative integer ; it is often denoted as | s |.
Trump will probably make a show of eviscerating Biden’s climate plans while rebranding some of them as his own. Markets, in the end, may move in more or less the same direction.
Words such as circumdare ("to surround") are split apart with other words of the sentence in between, e.g. circum virum dant: "they surround the man" (circumdant (circum- prefix + dant)). This device is used in this way to create a visual image of surrounding the man by means of the words on the line.
