Evaluation of Search Time for Two Computerized Information Retrieval Systems at the University of Georgia
Peer reviewed Peer reviewed
Ware, Glenn O.; Park, Margaret K. – Journal of Documentation, 1973
Two statistical models for estimating search time have been developed for the CA Condensates data base using the University of Georgia Text Search System. Comparative timings between the Chemical Abstracts Service search program and the University of Georgia search program are made for the Ca Condensates data base. (5 references) (Author/NH)

An Information-Space Model for the Development and Application of Computer-Based Tools in Information Creation and Dissemination.
Peer reviewed Peer reviewed
Ashford, John – Journal of Documentation, 1997
Examines Boisot's model of information processes and information economics based on information space in three dimensions (I-space). I-space is used as a framework to explain the success of computer-based tools in information scanning and dissemination, and their failure to support problem areas in the process of knowledge creation, especially…

Interaction in Information Searching and Retrieval.
Peer reviewed Peer reviewed
Beaulieu, Micheline – Journal of Documentation, 2000
Explores the concepts of interaction and interactivity presented in different theoretical models in the fields of human-computer interaction (HCI) and information-seeking/searching behavior, and relates these to information retrieval (IR) research. Suggests that interaction in HCI is primarily concerned with establishing a user/system dialogue at…

Models in Information Behavior Research.
Peer reviewed Peer reviewed
Wilson, T. D. – Journal of Documentation, 1999
Presents an outline of models of information seeking and other aspects of information behavior, showing the relationship between communication and information behavior in general with information seeking and information searching in information-retrieval systems. Also presents an alternative, problem-solving model which provides a basis for…

Linking a Medical User Survey to Management for Library Effectiveness: II, A Checkland Soft Systems Study.
Peer reviewed Peer reviewed
Brember, V. L. – Journal of Documentation, 1985
Presents Checkland's soft systems methodology, discusses it in terms of the systems approach, and illustrates how it was used to relate evidence of user survey to practical problems of library management. Difficulties in using methodology are described and implications for library management and information science research are presented. (8…

Access to Moving Image Documents: Background Concepts and Proposals for Surrogates for Film and Video Works.
Peer reviewed Peer reviewed
O'Connor, Brian C. – Journal of Documentation, 1985
Examines fashioning of model for surrogate to facilitate user selection of appropriate film or video work for particular use. A matrix of time line and film or video document characteristics is proposed as primary aspect of surrogate graphic record, raising issues of description and sampling within abstracting process.
