Text Processing Task

A Text Processing Task is a data processing task whose input is a text dataset (of text items).

• Context:
  • Task Input: Text Item.
  • Task Output: Structured Text Document, Formatted Text, Annotated Text.
  • It can usually requires a Text Encoding-Decoding System.
  • It can be solved by a Text Processing System (that implements a text pre-processing algorithm).
  • It can range from being a Offline Text Processing Task to being an Online Text Processing Task.
  • It can range from being a Text Preprocessing Task to being a Text Post-Processing Task.
  • It can require a Text Encoding-Decoding Task.
  • …
• Example(s):
  • a Text Reading Task.
  • a Text Editing Task.
  • a Text Annotation Task.
  • a Word Processing Task.
  • a Document Preparation Task,
  • a Proofreading Task.
  • a Text Error Correction Task,
  • a Text Mining Task.
  • …
• Counter-Example(s):
  • a Source Code Processing Task, or a Math Notation Processing Task.
  • an Image Processing Task.
  • a Speech Processing Task.
• See: Text Entry Interface, Regular Expression Statement, Text Encoding-Decoding Task, Command-Line Interface (CLI), Graphical User Interface (GUI), PDF-to-Text Conversion Task.

  • In computing, the term text processing refers to the theory and practice of automating the creation or manipulation of electronic text.

    Text usually refers to all the alphanumeric characters specified on the keyboard of the person engaging the practice, but in general text means the abstraction layer immediately above the standard character encoding of the target text.

    The term processing refers to automated (or mechanized) processing, as opposed to the same manipulation done manually.

    Text processing involves computer commands which invoke content, content changes, and cursor movement, for example to

    • search and replace
    • format
    • generate a processed report of the content of, or
    • filter a file or report of a text file.
  • The text processing of a regular expression is a virtual editing machine, having a primitive programming language that has named registers (identifiers), and named positions in the sequence of characters comprising the text. Using these the "text processor" can, for example, mark a region of text, and then move it. The text processing of a utility is a filter program, or filter. These two mechanisms comprise text processing.

  • Since the standardized markup such as ANSI escape codes are generally invisible to the editor, they comprise a set of transitory properties that become at times indistinguishable from word processing. But the definite distinctions from word processing are that text processing proper:
    • represents "text processing utilities", not just "text editing" applications.
    • is much more "the keyboard way", as opposed to "the mouse way" (e.g. drag and drop, cut and paste) of initiating an edit.
    • is sequential access rather than random access in approach.
    • operates directly at the presentation layer rather than indirectly at the application layer.
    • works raw data that is standardized and works more openly rather than tending towards any proprietary methods.
  • In this way markup such as font and color are not really a distinguishing factor, because the character sequences that affect font and color are simply standard characters inserted automatically by a background text processing mode, made to work transparently by compliant text editors, yet becoming otherwise visible as text processing commands when that mode is not in effect. So text processing is defined most basically (but not entirely) around the visual characters (or graphemes) rather than the standard, yet invisible characters.
