AbstractThis is the second of two articles describing the development, testing, and evaluation of the Individualized Instruction for Data Access System (IIDA). The system was tested in an industrial setting and it was demonstrated that (1) end users of scientific and technical literature could learn to do their own bibliographic searches through computer‐assisted instruction as well as they learned through a comparable period of conventional instruction, and (2) end users were as satisfied with the results of their own searchings as with the result of searches performed for them, for the types of searches teste

摘要:

AbstractUp to the present a number of theoretical approaches has been developed in order to improve the effectiveness and/or efficiency of information retrieval. However, most of the information retrieval methods based on these approaches have never passed the stage of purely theoretical investigation, and experimentation, if carried out at all, has been very limited in scale. A closer examination of current theoretical developments and the present practice of information retrieval reveals that a combination of the existing theory of probabilistic retrieval into a practical methodology based on Boolean searches would be very promising. Such an extension of the probabilistic approach to information retrieval is outlined.

摘要:

AbstractThe focus of information research in any given discipline depends on the meaning of the word “information” for scientists in that discipline. This article lists some of the “disciplines of information,” including several with a strong systems orientation, and identifies those information scientists for whom a knowledge of systems methodology is important. This is followed by a broad‐brush treatment of the modern systems movement: its role in the changing worldview of science, some disciplines (e.g., cybernetics and operations research) that have contributed to its development, and the distinction that can be drawn between General Systems Theory (GST) and other approaches to the study of systems—a theme developed by Mattessich in the article t

摘要:

AbstractThis article offers a concise survey and glimpse of the vast literature presently available in the field of systems thinking and cybernetics. The first part discusses the areas of systems philosophy, systems analysis (mathematical systems theory), empirical systems research, and systems engineering, while the second part offers some details about the contributions of the following selected scholars: von Bertalanffy, Bogdanov, Ackoff, Churchman, and Herbert A. Simon. A bibliography of some 150 books and papers closes the article.

摘要:

AbstractI attempt in this article to show how systems theory presents us with a useful and interesting way of looking at the concepts of knowledge and information. Using a simple model from the (normative) theory of economic decision making, I try to illustrate how the idea of a system helps give meaning to the notion of “meaning.” I also introduce a distinction between structural information and parametric information, suggesting that the former, now somewhat neglected in the economic theory of information systems, may actually pose the more interesting questions for future resea

摘要:

AbstractEven though the word “information” has a number of different meanings, most scientific conceptions of information are unidimensional and quantitative. Such information concepts ignore the major issues of information processing in adaptive systems. A brief look at the information processing requirements of adaptive systems (focusing upon humans) suggests the existence of another dimension of information—that having to do with behavior and thus with pa
