This paper describes computer-based optical character recognition (OCR) systems, focusing on their components (the computer, the scanner, the OCR, and the output device); how the systems work; and features to consider in selecting a system. A list of 26 questions to ask to evaluate systems for potential purchase is included. (JDD)

Describes the hardware components of a CD-ROM workstation and offers guidelines for selection decisions. Components discussed include CD-ROM drives; keyboards; monitors, including color and monochrome; graphics; microcomputers, including memory requirements; disk storage, including hard disks and floppy disks; and printers. Turnkey systems are…

Describes the design of a prototype multiauthor multimedia document production (MAMMDP) system. Discusses the problems of finding an appropriate task analysis technique, and introduces background concepts. Examines how the system's tasks were analyzed and represented during the early stages of the design. (AEF)

Describes the Alexandria Digital Library, a geolibrary that focuses on geographical locations. Topics include the evolution of the system and interface design; design goals; user communities, including earth scientists, information specialists, and educators; user evaluation methodologies and findings; and future possibilities. (LRW)

Reports on a research project designed to develop an intelligent computer-based learning environment of industrial applications. "Jonas," an expert system, is part of a modeling/simulation environment which enables shop-floor workers to test and put new philosophies of work into practice in the context of manufacture. The approach focuses on the…

The pervasive use of communication technology in schools and universities requires increased security to safeguard information confidentiality, integrity, availability, utility, and authenticity. This article, the first of two, examines procedures for implementing security policy, techniques for minimizing vulnerability, and techniques for…

Examines key management issues involved in delivering geographic information services on the World Wide Web, using the Geographic Information Center (GIC) program at the University of Virginia Library as a reference. Highlights include integrating the Web into services; building collections for Web delivery; and evaluating spatial information…

Describes a new model for quantitatively assessing screen formats. Results of applying the model to data entry screens support the use of the model. Also described is a critiquing mechanism embedded in a user interface design environment as a demonstration of this approach. (Author/AEF)

Describes American Memory, a multimedia computer system that incorporates CD-ROM and videodisk to provide access in electronic format to some of the Library of Congress archival materials on American history. Highlights include participating libraries; contents of the collections; searching; evaluation; and examples of the system's use at Barnard…

Examines the Museum Educational Site Licensing (MESL) Project--a cooperative project between seven cultural heritage repositories and seven universities--as well as other developments of cultural heritage image databases for academic use. Reviews recent literature on image indexing and retrieval, interface design, and tool development, urging a…

Focuses on natural language processing (NLP) in information retrieval. Defines the seven levels at which people extract meaning from text/spoken language. Discusses the stages of information processing; how an information retrieval system works; advantages to adding full NLP to information retrieval systems; and common problems with information…

Describes an experimental system designed to organize and provide access to Web documents using a faceted pre-coordinate indexing system based on the Deep Structure Indexing System (DSIS) derived from POPSI (Postulate based Permuted Subject Indexing) of Bhattacharyya, and the facet analysis and chain indexing system of Ranganathan.

In May 1994, the first website for the School of Education at Indiana University Bloomington (IUB) was launched. At that time, the home page had two links: (1) The Instructional Systems Technology Department; and (2) The IUB home page. A decade later, the site now consists of more than 6,000 web pages, and has received more than 41.5 million page…

Existing educational systems built for cooperative and collaborative activities are most often based on the client/server paradigm of distributed computing. This article shows that a new model for distributed computing, Peer-to-Peer (P2P), provides new opportunities for building distributed educational applications. It begins by reviewing general…

Universities increasingly employ information technology to distribute elements of their educational programs beyond campus borders and to find new uses for the intellectual capital they produce. Some faculty, with varying support and success, are moving course materials--and sometimes courses themselves--to the Internet to reach wider audiences.…
