Trigrams are a special case of the n -gram , where n is 3. They are often used in natural language processing for performing statistical analysis of texts and in cryptography for control and use of ciphers and codes . See results of analysis of " Letter Frequencies in the English Language ".
7-836: Context is very important, varying analysis rankings and percentages are easily derived by drawing from different sample sizes, different authors; or different document types: poetry, science-fiction, technology documentation; and writing levels: stories for children versus adults, military orders, and recipes. Typical cryptanalytic frequency analysis finds that the 16 most common character-level trigrams in English are: Because encrypted messages sent by telegraph often omit punctuation and spaces, cryptographic frequency analysis of such messages includes trigrams that straddle word boundaries. This causes trigrams such as "edt" to occur frequently, even though it may never occur in any one word of those messages. The sentence "the quick red fox jumps over
14-428: Is "a frame that surrounds the event and provides resources for its appropriate interpretation". It is thus a relative concept, only definable with respect to some focal event within a frame, not independently of that frame. In the 19th century, it was debated whether the most fundamental principle in language was contextuality or compositionality , and compositionality was usually preferred. Verbal context refers to
21-585: The coherence relation between sentences. Neurolinguistic analysis of context has shown that the interaction between interlocutors defined as parsers creates a reaction in the brain that reflects predictive and interpretative reactions. It can be said then that mutual knowledge, co-text, genre, speakers, hearers create a neurolinguistic composition of context. Traditionally, in sociolinguistics , social contexts were defined in terms of objective social variables, such as those of class, gender, age or race. More recently, social contexts tend to be defined in terms of
28-451: The current communicative situation. In this sense, language use or discourse may be called more or less 'appropriate' in a given context. In the theory of sign phenomena, adapted from that of Charles Sanders Peirce , which forms the basis for much contemporary work in linguistic anthropology , the concept of context is integral to the definition of the index , one of the three classes of signs comprising Peirce's second trichotomy. An index
35-441: The lazy brown dog" has the following word-level trigrams: And the word-level trigram "the quick red" has the following character-level trigrams (where an underscore "_" marks a space): Context (language use) 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
42-424: The social identity being construed and displayed in text and talk by language users. The influence of context parameters on language use or discourse is usually studied in terms of language variation , style or register (see Stylistics ). The basic assumption here is that language users adapt the properties of their language use (such as intonation, lexical choice, syntax, and other aspects of formulation ) to
49-442: The text or speech surrounding an expression (word, sentence, or speech act ). Verbal context influences the way an expression is understood; hence the norm of not citing people out of context . Since much contemporary linguistics takes texts, discourses, or conversations as the object of analysis, the modern study of verbal context takes place in terms of the analysis of discourse structures and their mutual relationships, for instance
