Roman Jakobson (1896–1982) elaborated the idea that the production and interpretation of texts depends on the existence of codes or conventions for communication. Since the meaning of a sign depends on the code within which it is situated, codes provide a framework within which signs make sense (see Semiosis ).
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.
James Porter defined the discourse community as: "a local and temporary constraining system, defined by a body of texts (or more generally, practices) that are unified by a common focus. A discourse community is a textual system with stated and unstated conventions, a vital history, mechanisms for wielding power, institutional hierarchies ...
Instead, it is a separate system with its own norms, structures, and stylistic conventions, and it often evolves differently than its corresponding spoken or signed language. Written languages serve as crucial tools for communication, enabling the recording, preservation, and transmission of information, ideas, and culture across time and space.
Protocols are to communication what algorithms or programming languages are to computations. [3] [4] Operating systems usually contain a set of cooperating processes that manipulate shared data to communicate with each other. This communication is governed by well-understood protocols, which can be embedded in the process code itself.
More recently, social contexts tend to be defined in terms of the social identity being construed and displayed in text and talk by language users. [ citation needed ] The influence of context parameters on language use or discourse is usually studied in terms of language variation , style or register (see Stylistics ).
Transcription should not be confused with translation, which means representing the meaning of text from a source-language in a target language, (e.g. Los Angeles (from source-language Spanish) means The Angels in the target language English); or with transliteration, which means representing the spelling of a text from one script to another.
For broader coverage of this topic, see Writing. A writing system comprises a set of symbols, called a script, as well as the rules by which the script represents a particular language. The earliest writing was invented during the late 4th millennium BC. Throughout history, each writing system invented without prior knowledge of writing gradually evolved from a system of proto-writing that ...
