Data redundancy

Redundancy ( from Lat redundare - be present in abundance; plural: redundancies) is understood in the theory of language, the multiple naming of information that are not necessary for understanding the overall context. It represents an important means of rhetoric and repeated content which are taken from the individual listeners immediately. A basic distinction between the beneficial redundancy, whose aim is to ensure the existence of the information content and the empty redundancy, in which this intention is missing. Under syntactic redundancy is understood, however, for example, a transitive verb, which implies a categorical object mentally.

In communication science can - in contrast to the information and language theoretical redundancy terms - understand redundancy as opposed to news. While the information theoretic redundancy ( 1st order ) to characters (symbols 1st order ) and the linguistic ( grammatical ) redundancy ( 2nd order ) to words (symbols 2nd order ) relate, repeat the redundancy in communication sciences ( 3rd order ) all statements. Therefore, the communication science redundancy concept is derived from the concept of information communication science. This statement defines information as newsworthy. That is, an information must satisfy two conditions: first, it must contain a statement that it must not be vacuous (empty). Second, it must not repeat already familiar. In this sense, Harry Pross defined information as a correlate of ignorance. Scientific communication considers itself constituted redundancy (usually ) at the recipient ( reader, receiver, listeners, etc. ) of communication, as only they can decide whether information is new or already known.

Redundancy is achieved in that information

  • Easily memorable for the recipient
  • Can be absorbed by the recipient in the case of a fault or short distraction

There are some rhetorical figures which are based on the principle of redundancy:

  • Geminatio
  • Pleonasm
  • Tautology

Examples:

  • Beneficial redundancy:
  • Empty redundancy:
  • Syntactic redundancy: "I write " (implies theoretically a text / letters ... )
  • Linguistic redundancy: "D Rdndnz ntrlchr Sprchn st zmlch GRSS. " Even without vowels still understandable.
