Focuses on human behavior in the information-seeking process, and identifies behaviors influencing the design of information retrieval system interfaces. Discusses the principles of saturation, concreteness, least resistance, familiarity, stimulation, certainty, simplicity, and following-form. (PEN)

Discusses the need to focus on the human dimension to encourage considerate behavior among Internet users, and considers the confidentiality of transactions between librarians and users. Highlights include developing a user focus; individuality and privacy; harassment; management information; research on privacy at Loughborough University; and…

Introduces a new model for analyzing teachers' conversations in computer-mediate communication (CMC) based on information from Bakhtin (1981), Freire (1993), social identity theory, psychological capital, cultural consciousness, and CMC theoretical frameworks. Considers CMC and human-computer interaction (HCI) to address cultural differences that…

Describes the "Capture Lab"--a computer-supported conference room designed to capture the thought processes, plans, and decisions of business teams. Discusses how groups have used this environment for collaborative writing. Shares observations of how users respond to the technology and how they learn to use the room. (RS)

Presents evidence to show that the body plays a continuing and fundamental part in the process of thinking and the development of the knowledge used to think. Topics discussed include knowledge structures and representations; artificial intelligence; feeling; learning processes; models of knowledge; information retrieval; and implications for…

Discusses methods for the retrieval of help knowledge items using graphical tree structures that conform to the hierarchical nature of the tutorial information being referenced. The implementation of "Study Tree Presenter," a special purpose "hypertext shell" that provides such access is described and several samples of screen…

A comparison of the theoretically enormous potential of computer assisted instruction (CAI) to individualize instruction with its limited present-day realization indicates that computers are limiting to students. Rather than attributing effective CAI to its mythical ability to tailor instruction, instructional developers should evaluate exactly…

Discussion of the use of dynamic data resources, such as Internet LISTSERVs or Usenet newsgroups, focuses on an experiment using an automated filtering system with Usenet newsgroups. Highlights include user satisfaction, based on retrieval size, data sources, and user interface and the need for some human mediation. (Contains two references.) (LRW)

Discussion of users and information retrieval systems highlights a study that investigated the representation of users' knowledge by examining their names for objects and concepts, agreement on names, the Library of Congress Subject Headings representation for similar objects and concepts, and measurement of the similarity between these…

Unlike conventional information retrieval systems, natural language processing (NLP) systems translate queries automatically into the language of the system. This paper discusses the potential impact of NLP on both the indexing and retrieval of text and examines some current NLP projects and systems that have established knowledge bases in narrow…

Provides an overview of the articles in this special issue, which deals with the portability, or transferability, of educational computer software. Motivations for portable software relating to cost, personnel, and time are discussed, and factors affecting portability are described, including technical factors, educational factors, social/cultural…

Discusses basic principles of human-computer interface design that will be helpful to librarians involved in designing effective OPAC (Online Public Access Catalog) screens. Highlights include physical features; general principles; menu screens; commands; inquiry screens; messages, including help screens; and organizational considerations,…

Introduces navigation as a central concept for information retrieval and for information systems in general. The evolution of information systems is described; navigability as an aid to improve relevance is discussed; and a system under development that attempts to facilitate navigation for information retrieval is described. (31 references) (LRW)

Discussion of virtual reality (VR) focuses on research and development being carried out at NYNEX to solve business problems. Component technologies are described; design decisions are considered, including interactivity, connectivity, and locus of control; potential perils of VR are discussed, including user dissociation; and areas of promise are…

Describes a study of graduate students that observed the interaction between users of a graphical statistical package and a human playing the role of a simulated intelligent advisory system to guide the design of advice-offering user-assistance software. The use of video to examine the users' role in the interaction is discussed. (Contains 37…
