The edi conceptual model is being developed to define common structures, services, and processes that syntax-specific standards like X12 and EDIFACT could adopt. Open Systems Interconnection (OSI) is of interest to edi because of its potential to help enable global interoperability across Electronic Data Interchange (EDI) functional groups. A…

Describes the emergence of Open Systems Interconnection (OSI) as it relates to the U.S. Government Open Systems Interconnection Profile (GOSIP); defines GOSIP; and speculates about its future. Challenges facing GOSIP that are related to test policies and procedures, strategic and tactical planning, additional functionality, and international…

Describes an application-specific hypertext system designed to facilitate and capture policy and design discussions. The discussion includes an introduction to the Issue Based Information Systems (IBIS) method; a description of this graphical IBIS (gIBIS) tool; an example of a gIBIS interaction; and thoughts about future research. (13 references)…

Describes a prototype automated collection analysis system developed at OCLC that allows a library to compare its collection with both predefined and evaluator defined peer groups. Eight library applications for such comparisons are listed, and the system design goals and areas needing further development are discussed. (five references)…

Outlines a systematic approach for evaluating the needs and potential problems involved when school districts seek to update their current information systems. Considers the following components: financial, technical, computer literacy, and information system management infrastructure. (MLF)

Discussion of the philosophies and theories of language learning focuses on the development of a hypermedia language program. Levels of knowledge analysis are discussed, communicative language proficiency is described, learner interactions with the hypermedia program are examined, and the relationships of communication and culture are discussed.…

Describes the development, implementation, and evaluation of a voice interface for the British Library Blaise Online Information Retrieval System. Results of the evaluation show that the use of currently available speech recognition and synthesis hardware, along with intelligent software, can provide an interface well suited to the needs of online…

Describes the design and implementation of an interactive video system using existing videodiscs and Apple's Hypercard for use in the teaching of cell biology to undergraduate biology students. Hypertext and hypermedia are discussed, the hardware configuration is described, and a preliminary evaluation of the completed system is reported. (five…

Examines ways in which intelligent tutoring systems can be used to develop models of a student's domain knowledge, problem solving abilities, and learning strategies. Cognitive skills assessment is discussed, and an example of a problem based tutoring system, Qualitative Understanding of Electrical System Troubleshooting (QUEST), is explained. (25…

Describes the development and production of an interactive multimedia resource on twentieth-century artist, Constatin Brancusi, by an international consortium of art museums, art historians, and technical partners. Topics discussed include technical issues, such as hardware and software; design considerations; international cooperation; and…

Discusses standards for the design and implementation of the electronic data networks developed for, and adopted by, the Pittsburgh Public Schools as district policy. Describes the layered approach which includes the physical layer, the protocol layer, and the application layer, and recommends hardware. A sidebar features court television in high…

Discusses how the World-Wide Web (WWW) can be linked to the PAT system, a search engine supporting access to Standard Generalized Markup Language (SGML) encoded documents. Technical concepts are reviewed, and the operation of a PAT-to-Web gateway is explained using examples of how it is employed. (JKP)

Despite plans for corporate training networks, digital ad-insertion systems, hotel video-on-demand, and interactive television, only small scale video networks presently work. Four case studies examine the design and implementation decisions for different markets: corporate; advertising; hotel; and commercial video via cable, satellite or…

Considers the possibility of designing CAI (computer-assisted instruction) systems that are managed by semantic networks. Topics discussed include general descriptions of the suggested approach, lesson-presentation modes, and the architecture of a CAI system managed by a semantic network. (10 references) (MES)

Addresses research results and controversies concerning the ergonomic design of computer work stations ranging from the traditional concerns with anthropometric fashions, work posture, and visual performance to the recent considerations about human information processing capacities and awareness of problem-solving strategies. (eight references)…
