The equation R x A = B x E = I describes the model of pragmatic information (W.v. Lucadou, 1987). While conventional information theory as developped by C. E. Shannon measures information in quantifiable units - the bits, the concept of pragmatic information seeks to comprise information by it's meaning, or more general it's impact on a receiving system. The variables of the equation are Reliabilität (reliability), Autonomie (autonomy), Bestätigung (confirmation), Erstmaligkeit (novelty) and Pragmatische Information (pragmatic Information).
