Academic libraries customize, support, and provide access to myriad information systems, each with complex graphical user interfaces. The number of possible information entry points on an academic library Web site is both daunting to the end-user and consistently challenging to library Web site designers. Faced with the challenges inherent in…

Describes significant attributes of expert systems, contrasts them to conventional computer systems, and provides an overview of the R1 expert system used by Digital Equipment Corporation (DEC) to put together operational systems that meet customers' requirements. Document handling, particularly pictures and images in documents, is also briefly…

Critiques existing approaches to computerized support for browsing and describes four new types of browsers that have been implemented in the Xerox NoteCards hypertext system. These browsers support the process of pursuing and returning from digressions and facilitate the integration of diverse sets of materials that have been browsed. (16…

Discussion of human-computer interfaces focuses on the use of graphical and direct manipulation approaches to improve the user interface. Topics discussed include information seeking; computerized search capabilities, including full-text string searches, index searches, and hypertext; Boolean expressions; dynamic or direct manipulation queries;…

The Video PATSEARCH system consists of a microcomputer with a special keyboard and two display screens which accesses the PATSEARCH database of United States government patents on the Bibliographic Retrieval Services (BRS) search system. The microcomputer retrieves text from BRS and matching graphics from an analog optical videodisc. (Author/JJD)

Explains how to retrieve graphics that are available on the World Wide Web and add them to a Web page using a word processor that can save documents in an ASCII (American Standard Code Information Interchange) text format and a new version of Netscape. A list of various, unrelated Internet resources is also included. (LRW)

Presents an information systems navigation approach using a combination of functionalities encountered in classification processes, Hypertext systems, and information retrieval systems. The first version of the SYRIUS system is described, with emphasis on the user's graphic interface which integrates these functionalities. (26 references) (EA)

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…

Discusses ways to locate information on the Internet. Highlights include LISTSERVs; files to download, including text, graphics, software, sounds, and animations through Archie; locating files on a Gopher via Veronica; the World Wide Web; and electronic mail addresses. (LRW)

Summarizes types of machine access available for users of Chemical Abstracts Online, a database which can accept and print out graphics images of chemical compounds. The use of Tektronix terminals, capabilities and limitations of other types of graphic termials and microcomputers, and estimated costs are noted. (EJS)

The MARIE project explores knowledge-based information retrieval of captioned images of the kind found in picture libraries and on the Internet. MARIE's five-part approach exploits the idea that images are easier to understand with context, especially descriptive text near them, but it also does image analysis. Experiments show MARIE prototypes…

This report describes the videotex system, which allows access by the general public to large computer-based information sources, which contain pages of information to be displayed on suitably supplemented television receivers or newly designed videotex terminals. Some problems in introducing a videotex system suitable for today's technology which…

Describes ArchiVISTA, an optical disk image retrieval system that provides access to cartoons and caricatures in the National Archives of Canada. Planning, evaluation, design and image capture, and retrieval are explained, as well as how the system developed from earlier efforts of bibliographic control and imaging technology. (10 references) (EAM)

Describes the development of the Course Advising Tool (CAT), a microcomputer-based information retrieval program that uses hypermedia and visual programing tools to help students develop their course schedules. The use of graphical cues and nonsequential navigation is discussed, and possible extensions to the system are described. (19 references)…

This paper describes basic types of World Wide Web pages and presents design criteria for page layout based on principles of visual literacy. Discussion focuses on pages that present information in the following styles: billboard; directory/index; textual; and graphics. Problems and solutions in Web page construction are explored according to…
