In a document retrieval, or other pattern matching environment where stored entities (documents) are compared with each other, or with incoming patterns (search requests), it appears that the best indexing (property) space is one where each entity lies as far away from the others as possible; that is, retrieval performance correlates inversely…

If information science is to be considered a "science" in the true sense of the word, a set of general concepts and analytical expressions must be developed. Fundamental to this development is a rigorous and quantifiable measure of information. In previous papers a general framework, called a generalized information system, is suggested…

The use of readability principles in the ERIC guidelines for abstracting suggests that abstracts should be more readable than source documents. However, information theory suggests that the compression of information would result in less readable abstracts. Abstracts and their source documents were selected randomly from each of four…

An act of rhetoric has attitudinal significance; that is, a part of rhetoric involves persuasion. Further, attitudinal frames of reference relate to and result from the retrieval of stored information (memory, etc.) and the generation of arguments. By studying the relative strength that subjects use in arguing an "issue-concept," the…

A communication arc from A to B represents the transmission of a single message from the first system A to the second system B. What are all the ingredients of a communication arc required for the sending of a message? What compatibility conditions between these two systems must be satisfied in order for communication to take place? Further, what…

Information theory was used to qualify the difficulty of verbal discrimination (VD) learning tasks and to measure VD performance. Words for VD items were selected with high background frequency and equal a priori probabilities of being selected as a first response. Three VD lists containing only 2-, 3-, or 4-word items were created and equated for…

The curriculum materials and computer programs in this booklet introduce the idea of a matrix. They go on to discuss matrix operations of addition, subtraction, multiplication by a scalar, and matrix multiplication. The last section covers several contemporary applications of matrix multiplication, including problems of communication…

The classification of communication activity into interpersonal and mass communication is inadequate. A third category, "medio" communication, is also needed. Examples of this third type include point-to-point telecommunication (such as the telephone or mobile radio), surveillance telecommunication, and closed-circuit television. Medio…

Reports on applications of bibliometrics (measurement of book or compositional entities according to methods that yield comparable results) in the field of information science. Highlights include quantification and qualification, Bradford's Law of Scattering, applications and classifications of citation analysis, and bibliometrics in library…

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.

Technology should not be allowed to dictate objectives and procedures; the study of users and their needs, and the social role of information transfer, should be given more emphasis in curricula in order to avoid over-emphasis on techniques at the expense of services. (8 references) (Author)

The advancement of science through information transfer and the role of operations research and information science in this process are re-examined by the author in terms of the rise of technological disillusionment, scientific recession and concern with the limits of growth. (21 references) (Author/KE)

The psychological inadequacies and political dangers of problem-solving as a pedagogical concept" are explored. (Author/DR)

It is suggested that the study of artificial intelligence can provide ways of thinking about the human mind that are potentially valuable in formulating cognitive theories. Theoretical psychology is proposed as an appropriate classification for this branch of theory. (MSE)
