Reviews problems with the World Wide Web that can be attributed to human error or ineptitude, and provides suggestions for improvement. Discusses poor Web design, poor use of search engines, and poor quality control by search engines and directories. (AEF)

Distance education created new challenges regarding the delivery of large size isochronous continuous streaming media (SM) objects. In this paper, we consider the design of a framework for customized SM presentations, where each presentation consists of a number of SM objects that should be retrieved and displayed to the user in a coherent…

Hypermedia and object oriented programming systems (OOPs) represent examples of "open" computer environments that allow the user access to parts of the code or operating system. Both systems share fundamental intellectual concepts (objects, messages, methods, classes, and inheritance), so that an understanding of hypermedia can help in…

InterBrowse, a uniform interface information retrieval application for several different databases, is designed to be used in Intermedia, a hypermedia environment currently under development at Brown University's Institute for Research Information and Scholarship. This application arose out of the recognized need for an interface that can be used…

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)

Presents a new extraction pattern, modified Document Type Definition (mDTD), which relies on analytical interpretation to identify extraction target from the contents of Web documents. Experiments with 330 Korean and 220 English Web documents on audio and video shopping sites yielded an average extraction precision of 91.3% for Korean and 81.9%…

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…

This article briefly describes the development of bibliographic retrieval systems in the Instituto de Beneficio di Minerales (IN BE MI) in Salta, Argentina, using the Mini-micro CDS/ISIS software developed by Unesco. (LRW)

Authority control improves users' access to a library's holdings by enhancing the ability to find and select materials. The AutoCat authority control system developed at Dickinson College (Carlisle, Pennsylvania) avoids the high initial costs of vendor clean up and Library of Congress authority tapes while reducing the labor involved in authority…

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 the problem of control in documentary information retrieval (IR) systems focuses on feedback mechanisms. Information needs are discussed, particularly the Problem Oriented Information Need (POIN); the structure of an adaptive IR system is described; and the design of algorithms for automated IR systems is explained. (33 references)…

Describes a collaborative, reuse hypertext system, called MUCH (Many Using and Creating Hypertext). The novel browsing and retrieval characteristics of the system are based on a semantic net connecting documents, thesauri, and discussions. Word patterns are documented for reuse, creating and reorganizing network traversal according to user…

Describes a low-cost, upgradeable, CD-ROM network and gives a step-by-step description of the installation process, including inventorying assets, learning about network components, selecting a network, installing adapter boards, attaching cabling, installing software, testing, configuring the server, installing search software, installing a menu,…

This article continues the description of DFT (Document, Find, Theseus), an online documentation system that provides computer-managed on-demand printing of software manuals as well as the interactive retrieval of reference passages. Document boundaries in the hypertext database are discussed, search vocabulary complexities are described, and text…
