The bag-of-words model (BoW) is a model of text which uses an unordered collection (a "bag") of words. It is used in natural language processing and information retrieval (IR). It disregards word order (and thus most of syntax or grammar) but captures multiplicity .
When analyzing the structure of language statistically, a useful place to start is with high frequency context words, or so-called Key Word in Context (KWICs). After millions of samples of spoken and written language have been stored in a database, these KWICs can be sorted and analyzed for their co-text, or words which commonly co-occur with them.
Rhetorical structure theory (RST) is a theory of text organization that describes relations that hold between parts of text.It was originally developed by William Mann, Sandra Thompson, Christian M. I. M. Matthiessen and others at the University of Southern California's Information Sciences Institute (ISI) and defined in a 1988 paper.
Text linguistics is a branch of linguistics that deals with texts as communication systems.Its original aims lay in uncovering and describing text grammars.The application of text linguistics has, however, evolved from this approach to a point in which text is viewed in much broader terms that go beyond a mere extension of traditional grammar towards an entire text.
Cohesion is the grammatical and lexical linking within a text or sentence that holds a text together and gives it meaning. It is related to the broader concept of coherence. There are two main types of cohesion: grammatical cohesion: based on structural content
A sentence diagram is a pictorial representation of the grammatical structure of a sentence. The term "sentence diagram" is used more when teaching written language, where sentences are diagrammed. The model shows the relations between words and the nature of sentence structure and can be used as a tool to help recognize which potential ...
John E. Joseph identifies several defining features of structuralism that emerged in the decade and a half following World War I: Systematic Phenomena and Synchronic Dimension: Structural linguistics focuses on studying language as a system (langue) rather than individual utterances (parole), emphasizing the synchronic dimension.
It is the study of a text without taking into account any outside influence. Formalism rejects or sometimes simply "brackets" (i.e., ignores for the purpose of analysis) notions of culture or societal influence, authorship, and content, and instead focuses on modes, genres, discourse, and forms.
