Discusses the CODER system, which was developed to investigate the application of artificial intelligence methods to increase the effectiveness of information retrieval systems, particularly those involving heterogeneous documents. Highlights include the use of PROLOG programing, blackboard-based designs, knowledge engineering, lexicological…

Thirty junior high students with and without learning disabilities used three forms of an encyclopedia--printed, electronic with menus, and electronic with commands. Students without disabilities were more successful in retrieval. Both groups were more successful at simple versus complex tasks, assigned versus self-selected tasks, and when using…

Examines expert system shells and the role a microcomputer-based expert system can play as an intelligent job aid. Characteristics of traditional and automated job aids techniques are described, and the role of instructional designers in developing expert systems within organizations is discussed. (Author/LRW)

Reviews the 1986 literature on research in the areas of cataloging, subject access, user interface, and administration. The majority of papers selected for inclusion are descriptive studies (surveys using questionnaires or interviews) or case studies of one of more libraries. Thirty-eight references are listed. (MES)

This paper reviews the history of separate online system interfaces which led to efforts to develop expert systems for searching databases, particularly for end users, and introduces the research on such expert systems. Appended is a bibliography of sources on interfaces and expert systems for online retrieval. (Author/EJS)

Describes the mouse and other pointing devices used with microcomputers to facilitate easier user-microcomputer interaction, reviews previous educational applications and research, presents a study comparing the efficiency of the mouse with users of different ages, and discusses the implications for software design. (MBR)

A number of projects over the past decade, in a range of educational contexts, have sought to link forms and patterns of communicative interaction to improvements in knowledge, conceptual understanding and reasoning skills. These initiatives have produced dialog models, methodologies for developing these in ways that lead to the design of…

Briefly describes some experiments in human-machine interaction in the context of its relevance to multimedia audiovisual instruction, with emphasis on the use of microcomputer systems augmented with slides or audiocassettes. Fifteen references are listed. (Author/LLS)

Reviews the literature on the use of Web search engines in information science research, including: ways users interact with Web search engines; social aspects of searching; structure and dynamic nature of the Web; link analysis; other bibliometric applications; characterizing information on the Web; search engine evaluation and improvement; and…

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)

Examines current research on the implications of and the potential for two speech technologies: speech synthesis or response, i.e., speech output from a computer; and speech recognition, i.e., speech input to a computer. Human factors research is discussed; library applications are described; and future possibilities are considered. (Contains 148…

Discusses general issues of computer and human understanding; contrasts three paradigms of information retrieval methodology, including statistical, deep semantic or natural language, and smart Boolean; describes CONIT, a knowledge-based intermediary retrieval assistance system; and examines system evaluation procedures, including a…

Synthesizes major findings from research on the magnitude of individual differences in information retrieval (IR) tasks and suggests implications for practice and design of IR systems and interfaces. Topics discussed include indexing consistency, relevance judgments, selection of subject headings, selection of search terms, and search retrievals.…

Arguing that what sets the computer apart from all other teaching devices is its potential for interactivity, this paper examines the concept of interactivity and explores ways in which its power can be harnessed and put to work. A discussion of interactivity in human-to-human communication sets a context within which to view human/computer…

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…
