Research on cognitive modeling of information search and Web navigation emphasizes the importance of "information scent" (the relevance of semantic cues such as link labels and headings to a reader's goal; Pirolli & Card, 1999). This article shows that not only semantic but also structural knowledge is involved in navigating the Web…

Lakeland College, a small rural institution on the Canadian prairies, used to face the dilemma of needing a Web presence without having the funds, staff, and technology infrastructure to support it. This article relates how Lakeland's librarian hired ShirWin Knowledge & Learning Systems, Inc., a small software company based in Edmonton,…

Discussion of performance support focuses on Canada's Bell-Northern Research's views of embedded performance support systems. The establishment of a corporate center of excellence for performance support system (PSS) development is explained; a pilot project is described; and a business case showing the benefits of implementing a PSS is presented.…

Discussion of the design of information systems for exchanging educational research-based information focuses on the development of the Educational Resources Information Center (ERIC), British Education Index (BEI), Canadian Education Index (CEI), and Australian Education Index (AEI) and examines how they meet the challenges of educational reform…

Discusses the architecture of a global hypermedia information and communication system designed to operate through the Internet that is being developed at the Graz University of Technology (Austria). Topics addressed include clients and servers; distributed hypertext; link server protocol; document cache servers; and applications of the global…

Discusses the need for online help for end-users based on experiences with an online public access catalog (OPAC) at the University of Cape Town libraries. The concept of end users is examined, the role of search intermediaries in information systems is explained, and online help and systems design is discussed. (LRW)

Describes a system that was developed in Germany for natural language processing (NLP) to improve free text analysis for information retrieval. Techniques from empirical linguistics are discussed, system architecture is explained, and rules for dealing with conjunctions in dependency analysis for free text processing are proposed. (13 references)…

Discussion of human-computer interaction (HCI) as an essential part of the design of computing systems focuses on incorporating HCI into university computing courses. HCI training needs for various career profiles are given; and an outline of the contents of the Open University postgraduate module on HCI is appended. (nine references) (LRW)

Introduces, through a conversation with computer-system designers from the Netherlands, the Language/Action Perspective on modeling business workflow and communication processes. Describes their attempts to develop system models that go beyond data flow to incorporate the communicative actions or transactions that result in the creation of a…

Describes a microcomputer-based microfilm management system that has been developed in a medium-sized manufacturing firm's library in Hong Kong. The system configuration is explained, a design and selection plan for a microfilm format is discussed, a selection plan for hardware is described, and an indexing system is explained. (nine references)…

This discussion of the design of user-initiated help systems in computers focuses on the information that users actively seek to help them with their tasks, with emphasis on how to help users ask the questions that will bridge the gap between the initial internal (mental) form of the query and their information need as expressed by the system.…

Information systems are a necessary, but not sufficient, condition for improving the efficiency of educational systems. Improving the Education Management Information System must be the foundation of any long-term effort to enhance the efficiency of the Nepalese system. Three critical conditions must be met to enhance system efficiency…

Describes issues an organization must consider when preparing for the creation and installation of an international wide area network (WAN) to help link developing countries. Hardware and software needs are considered; the use of commercial vendors is discussed; a needs assessment is described; and technical and cultural difficulties are…

The nature of the learner-machine interaction is of central importance in the design of guided discovery learning environments. The interface to a learning environment is the only way in which a learner has access to the functionality of the system, and conversely, the interface in the only way in which the tutoring component of the system has…

Because interaction is the only observable information people have about teaching processes, it follows that the primary aspect of intelligent tutoring systems (ITS) is interaction, and that future work on domains or student models should be driven by the needs identified in the study of interaction. This paper begins by examining the idea of…
