Information Science: Toward the Development of a True Scientific Discipline.

It is pointed out that if information science is to be considered a "true" science similar to physics or chemistry then it must have a set of concepts and analytical expressions which apply to the flow of information in a general way. Such expressions should be relatively independent of the particular context or application under consideration. Definitions of a rigorous nature for the fundamental quantities involved must be established. These must have general applicability and must be related to other known and measurable quantities. It is desirable also that they be capable of quantification. In several previous papers, the author and a colleague have described a model of a generalized information system which has wide, and perhaps universal applicability. This paper elaborates on this model and indicates the range of its applicability. Several fundamental quantities are defined specifically in a way which allows for quantification. It is pointed out in this paper that this model can be the basis for the development of a "true" science of information with all of the necessary requirements for a science. By the use of this model and the definition of a "true" science, the goals and requirements for a curriculum in information science are thus established. Various applications of information science must then exist in much the same way that many applications of physics exist. In the latter case, the applications usually give rise to various branches of engineering. In the case of information science, one of the applications is librarianship-although many others exist as well. Some of these are referred to in the paper. In particular, science information as a subset of information science is discussed. Within this context, information is defined as data of value in decision making. Quantitative measures of information can be obtained by relating information to specific observable actions which can be measured physically. [ABSTRACT FROM AUTHOR]
