This paper discusses problems concerning the design of educational applications in general, as well as specific problems connected with educational applications meant to be published on the Web. A new approach to the authoring and maintaining of Web-based educational applications is proposed which is based on the concept of hypermedia composites.…

Presents an information visualization workspace in which users are able to explore data presented in diverse but coordinated formats using related systems called Visage, SAGE, and selective dynamic manipulation (SDM). Discusses four dimensions for analyzing user interfaces that reveal the combination of design approaches needed for visualizations…

Introduces concepts of server security and includes articles and sidebars of firsthand accounts of consequences of not devoting enough time to security measures. Outlines the following factors to consider when evaluating a server's risk potential: confidentiality/reproducibility of the data; complexity of the system; backup system and hardware…

Discusses the shortcomings of present online catalogs and some concepts and implementations for hypercatalogs. A prototype for a hypertext-based library catalog, HyperKGB, is described and its design principles and functionality are outlined. (Author/AEF)

Explores the similarities, differences, and emerging trends among the fields of human performance technology, electronic performance support systems, technical communications, and instructional design to gain insights into how their evolution affects performance support. The tension between designed messages and tools, which allows users more…

Describes the development of a multimedia Web-based system in Europe which combines an autonomous approach to learning involving both collaborative and trainer-guided activities. Focuses on the opportunities offered by information and communication technology to the training of technicians who have to gain shared knowledge on water network…

Discusses archiving digital information and the need for organizations to develop policies regarding digital asset management (DAM) and storage. Topics include determining the value of digital assets; formats of digital information; use of stored information; and system architecture, including hardware and asset management software. (LRW)

Summarizes the development of information retrieval evaluation ideas, describes the design of the TREC (Text Retrieval Conference) experiments, and discusses the Okapi team's participation in TREC. Highlights include the Cranfield projects that tested the principles of information retrieval system design, test collections, weighting functions,…

Presents a conceptual overview of online information systems, emphasizing the distinction between hypertext (associative) and more traditional (search) models of information management. Five commercially available hypertext systems are reviewed, hypertext design issues are discussed, and the application of structured writing techniques to…

Describes a comparative study of the "help" facilities of 16 interactive information retrieval systems. Guidelines for the design of a "help" facility are presented and then used to evaluate the quality and friendliness of each system. Suggestions for the improvement of online "help" facilities are discussed. (31…

Discusses ways in which artificial intelligence could be applied to improve the ease of use, quality of retrieval, and organization of data in online services or CD-ROM. (MES)

Examines the rapidly growing role for technical communicators in the computer industry as members of the external design team. Describes the kinds of decisions they are responsible for with regard to all phases of product development--as user advocates, usability testers, screen designers, and online documentation specialists.
