How much information do natural systems store and process? In this work we attempt to answer this question in multiple ways. We first establish a mathematical framework where natural systems are represented by a canonical form of edge-labeled hidden fc models called e-machines. Then, utilizing this framework, a variety of measures are defined and…

Situationally relevant items of information are those that answer, or logically help to answer, questions of concern. Significant situationally relevant information is explained in terms of changes of view in relation to questions of concern. It is claimed that situational relevance is an explication of the ordinary notion of practical relevance.…

This 440-item annotated bibliography presents a highly selected list of documents which focus on information theory applications to information science, information processing, or information systems analysis and design. The bibliography is arranged alphabetically by author and a subject/keyword index is provided.

Speculates on unanticipated effects brought about by the application of online sytems and databases to library services. Concern is voiced about the development of a technological library elite, the growth of research dependency, the limiting of the availability of books and journals, and the narrowing of serendipity in research.

Uses Kintsch's proposition-based construction-integration theory of discourse comprehension to detail the user coding operations that occur in each of the three subsystems (Perception, Comprehension, Application) in which users process an information retrieval systems (IRS) message. Describes an IRS device made up of two separate parts that enable…

For the purposes of this Directory, information science includes the following subjects: library and information systems, library automation and networks, systems analysis, management information systems, information needs and uses, abstracting and indexing, advanced classification theory, non-traditional techniques of organizing knowledge,…

The report presents a summary of science information research activities of the School of Information and Computer Science, Georgia Institute of Technology. Included are project reports on interrelated studies in science information, information processing and systems design, automata and systems theories, and semiotics and linguistics. Also…

This paper demonstrates an approach which enables one to reduce in a systematic way the immense complexity of a large body of knowledge. This approach provides considerable insight into what is known and unknown in a given academic field by systematically and pragmatically ordering the information. As a case study, the authors selected…

This study of the computer/user interface investigated the role of the computer in performing information tasks that users now perform without computer assistance. Users' perceptual/cognitive processes are to be accelerated or augmented by the computer; a long term goal is to delegate information tasks entirely to the computer. Cybernetic and…

Information is defined as data of value in decision making. Computer and Information Science is the study of information flow in a system and the processing of that information. These concepts are related to problem solving and the design of engineering curricula. (Author/TS)

Discusses how the concept of information is fundamental to many branches of science, technology, and mathematics and how a systematic use of the information concept can help to bridge the gap between different subjects in school. (HM)

Information systems for the sciences and professions should differ from those of traditional libraries because their purpose is to disseminate information, not to archive it, and their holdings should reflect user needs, not the size of the knowledge base. Various information system models may be identified, such as the discipline-oriented, the…

The efficient use of information depends on the way it is organized. Haphazard information may serve some useful purpose, but for a particular purpose, information needs to be processed into another structure which more easily fulfills that purpose. This booklet examines the concepts of information and information processing with the intention of…

This paper presents an overview of biocybernetic communication research, which deals with the information impact of films, television, photographic pictures, paintings, exhibitions, texts, and verbal stimuli on human beings. The first section describes the biocybernetic basics of biometric research, and clarifies terms used in the field. The…

THIS REPORT SYNTHESIZES FOUR YEARS WORK AND THOUGHT AIMED AT DESIGNING AND TESTING A SERIES OF COURSE SYLLABI FOR STUDY IN THE BASIC AREAS OF THE INFORMATION SCIENCES. THE RESULTS OF THE WORK ARE PRESENTED AS AN ARRAY OF COURSES IN FIVE GENERAL AREAS--(1) INFORMATION SYSTEM ANALYSIS, INCLUDING STUDY OF SPECIFIC SYSTEM PROBLEMS OF TECHNIQUES OF…
