Proposes a three-level framework for classifying elearning (electronic learning) interactions in distance education. Illustrates how the framework may be used to design and sequence electronic learning interactions, analyze planned interactions to reduce the need for costly revisions, and organize research to help interpret findings and guide…

Intended for potential business users, this paper describes the main characteristics of expert systems; discusses practical use considerations; presents a taxonomy of the systems; and reviews several expert system development projects in business and industry. (MBR)

Presents an information systems navigation approach using a combination of functionalities encountered in classification processes, Hypertext systems, and information retrieval systems. The first version of the SYRIUS system is described, with emphasis on the user's graphic interface which integrates these functionalities. (26 references) (EA)

Defines and delineates hypermedia by examining its relation to the user as a system, an interface, and an environment. Classes of computer systems are described; classes of hypermedia systems are explained; user work components are discussed, including tasks, information, and the environment; and emerging standards and future developments are…

Examines relationships between the two major components of computer simulations, the computer and participants; highlights major differences between computer-assisted, computer-based, and computer-controlled simulations; and describes three computer-assisted simulations to illustrate the interdependence of the major components.

Explores the future of reference librarianship within the context of the enabling technologies that will chart library development in the 21st century. The article types libraries into categories of "traditional,""automated,""hybrid," and "digital." The typology delineates shifts in human/machine…

This paper describes an experiment in the use of Dewey Decimal Classification in online catalogs to introduce classed approach to subject searching of library collections, enhance subject terminology indexed in online catalog, and provide possibilities for search strategies not possible through alphabetical approach of subject headings and/or…

Describes the design and development of an image database for photographs in the Ulster Museum (Northern Ireland) that used parallelism from a transputer network. Topics addressed include image processing techniques; documentation needed for the photographs, including indexing, classifying, and cataloging; problems; hardware and software aspects;…

Presents a classification scheme for generations of online catalogs; discusses current online technologies and identifies deficiencies; and discusses enhancements that will take online catalogs into the next generation. Such enhancements will include increased access to information through user-system dialogue, automatic search aids, subject…
