A Generalized Conceptual Development for the Analysis and Flow of Information.
Whittemore, B. J.; Yovits, M. C.
A generalized framework for developing analytical and conceptual relationships involving the flow of information has been suggested. This paper provides further refinement, rigor, and extension for some of the earlier relationships suggested. In particular, a measure of the amount of information is defined as the difference of the value of the decision state of the decision-maker after and before receipt of the message. This measure is universally applicable for all information that is concerned with the effectiveness of the message upon the recipient. It is accordingly called "pragmatic information." The definition is a direct consequence of the interdependence between information and decision-making and of the definition that "information is data of value in decision-making." In order to evaluate this measure of information, it is convenient to use a "generalized information system model" which has previously been proposed and which has virtually universal applicability. Each data set or document has some average amount of information content for a decision-maker of any given "effectiveness." The relationship of this average amount of information as a function of the decision-maker effectiveness is suggested as an important functional relationship that exists for every document. It is called an "information profile" of that document or data set. A typical information profile is suggested. (Author/NH)
