Griffith, Belver C. – Journal of the American Society for Information Science, 1988
Presents a system of software and analysis for the development of mathematical models designed to explain the structure in large bibliographic data sets. The discussion covers the goodness of fit obtained in testing and replications, and the implications for the control of large information systems. (six references) (CLB)

Henrion, Max; And Others – Journal of the American Society for Information Science, 1986
The purpose of this evaluation of DEMOS, a system for decision modeling and uncertainty analysis, was to identify some generic issues of interest in the design of such information systems, obtain insights about the causes of problems in their use, and to suggest hypotheses about how to deal with them.

Frisse, Mark F.; Cousins, Steve B. – Journal of the American Society for Information Science, 1992
Discusses hypertext and describes three abstract models that represent different levels in the design-decision process necessary for effective hypertext development. The use of information management software is discussed; combining hypertext and information retrieval models is considered; and opportunities for hypertext are described, including…

Santhanam, Radhika; Wiedenbeck, Susan – Journal of the American Society for Information Science, 1991
Describes research that was conducted to investigate the needs and characteristics of noncomputer professionals who use word processing software on personal computers. A model of the intermittent user's performance is presented, and two experiments are described that examined differences in mode of interaction and the use of online help. (30…

Cooper, Michael D. – Journal of the American Society for Information Science, 1991
Analyzes the skill acquisition sequence in using a software package and proposes advent models for investigating patterns of user interaction with information systems. The use of transaction log data is explained, advent function analysis is described, and tests of the models on longitudinal data are discussed. (26 references) (LRW)
