This report incorporates a literature review, a workshop paper, and discussion by workshop participants on the current status of research on what the users of computer systems know, and how these different forms of knowledge fit together in learning and performance. It is noted that such research is important to the problem of designing systems…

Describes SHRIF, a System for Heuristic Retrieval of Information and Facts, and the medical knowledge base that was used in its development. Highlights include design decisions; the user-machine interface, including the language processor; and the organization of the knowledge base in an artificial intelligence (AI) project like this one. (57…

This discussion of educational applications of user interfaces covers the benefits of adopting database techniques in organizing multimedia materials; the evolution of user interface technology, including teletype interfaces, analogic overlay graphics, window interfaces, and adaptive systems; application design problems, including the…

Different people have a diversity of needs and expectations when approaching an information retrieval system, and providing people with the ease and efficiency to access information is important when designing systems. By examining the man-machine interface from the cognitive viewpoint, it is possible to investigate how a person interacts with an…

This paper summarizes some of the current approaches to student modelling in Intelligent Tutoring Systems (ITS) and proposes ways in which learning algorithms can be applied in ITS. The role of machine learning in tutoring systems is described, including student modelling, teaching strategies, and collaborative learning. The PIXIE system and the…

Intermedia, a hypermedia system developed at Brown University's Institute for Research (Rhode Island) in Information and Scholarship, is first described, and then used as a case study to explore a number of key issues that software designers must consider in the development of hypermedia document systems. A hypermedia document system is defined as…

Using as a backdrop Vannevar Bush's 1945 discussion of the "Memex," his proposed system for organizing and storing information, this paper considers the development of intelligent multimedia knowledge systems. Particular attention is focused on learner needs and intentions in information seeking, and the implications of these factors for…

The first of three articles on the design of user interfaces for information retrieval systems discusses the need to examine types of display, prompting, and input as separate entities. The second examines the use of artificial intelligence in creating natural language interfaces, and the third outlines standards for case studies in human computer…

Reviews the background, concepts, and role of hypermedia systems and analyzes essential, expected, and desirable features of hypermedia in order to provide a basis for system design and evaluation. Four hypermedium shells and systems are described, and approaches to user interface problems are discussed. (48 references) (MES)

Describes a hypermedia system, HSYS, that was developed by the Idaho National Engineering Laboratory to investigate human performance in technologically complex operational settings, i.e., nuclear power plants and offshore oil platforms. Three subsystems are explained: (1) a knowledge base; (2) an embedded training module; and (3) an advisory and…

Discussion of speech recognition technology and its use in computer-assisted instruction focuses on prototype systems designed for medical education. Commercial speech recognition systems are described, hardware and software requirements are examined, and the use of a speech recognition system to streamline an existing user interface is discussed.…

Presents an overview of the ways in which user/system interaction in interactive information-retrieval (IR) systems has been treated in IR research and practice over the years. Describes the characteristics of a number of IR systems, as well as proposals for IR systems, in light of challenges set for by John Bennett in 1971. Contains 82…

This paper begins with a description of the context and background of cognitive research into knowledge acquisition and representation for computer based training. The nature of concept maps is alluded to and examples are given of the ways that maps can facilitate knowledge elicitation. It is noted that: (1) the concept knowledge in this research…

This survey of intelligent tutoring systems describes the components of these systems, different teaching scenarios, and the relation of these systems to a theory of instruction. It argues that the underlying pedagogical approach is to make latent knowledge manifest by using different forms of quantitative modeling: (1) simulating physical…

Describes the development, implementation, and evaluation of a voice interface for the British Library Blaise Online Information Retrieval System. Results of the evaluation show that the use of currently available speech recognition and synthesis hardware, along with intelligent software, can provide an interface well suited to the needs of online…
