Describes an intelligent tutoring system (ITS) that demonstrates how intelligent feedback can enhance conventional simulation-based training. An explanation is given of the Intelligent Conduct of Fire Trainer (INCOFT), which was designed to provide training exercises for soldiers operating the PATRIOT missile system, and its implications for…

The first of three articles on the design of user interfaces for information retrieval systems discusses the need to examine types of display, prompting, and input as separate entities. The second examines the use of artificial intelligence in creating natural language interfaces, and the third outlines standards for case studies in human computer…

Proposes a schematic multidisciplinary model to help developers of intelligent computer-assisted instruction (ICAI) identify the types of required expertise and integrate them into a system. Highlights include domain types and expertise; knowledge acquisition; task analysis; knowledge representation; student modeling; diagnosis of learning needs;…

Description of computer-based simulations focuses on the instructional functions of simulations and phases in the learning processes that should be activated by educational simulations. Highlights include a general model for simulation design; degree of learner control; complexity of the content; the role of the learner; and motivational…

Reviews the background, concepts, and role of hypermedia systems and analyzes essential, expected, and desirable features of hypermedia in order to provide a basis for system design and evaluation. Four hypermedium shells and systems are described, and approaches to user interface problems are discussed. (48 references) (MES)

Describes the development and integration of UDEMOG, a computer-assisted instruction system for teaching demographic related topics that was designed at the University of Delaware. Software programs and spreadsheet data files are described, hardware based on IBM equipment is discussed, and use in the classroom and in computer laboratories is…

Describes the design of an expert system developed using VP-Expert for document delivery decision making in a law library. Presents methods used in knowledge acquisition and knowledge representation after a brief review of the literature on expert system use in libraries. An appendix includes the rules of the expert system. (Author/AEF)

Discusses the results of modeling the performance of searching large text databases via various parallel hardware architectures and search algorithms. The performance under load and the cost of each configuration are compared, and a common search workload used in the modeling is described. (Contains 26 references.) (LRW)

Provides an overview of HYTREM (Hybrid Text-Retrieval Machine), a high-performance, cost-effective text-retrieval machine that handles information in large textual databases. Describes HYTREM's software and hardware design principles and presents an evaluation of system performance in relation to user demand and access versus system capacity. (JMV)

Examines the development of the main computer-aided careers guidance system in North America, along with the U.K. PROSPECT system. Discusses the roles of government, of the private sector, and of guidance professionals, in relation to the future of such systems, particularly in relation to guidance in Europe. (JPS)

Describes a computer system being developed to support two-party negotiation to enhance students' learning in the area of dispute resolution. The concept of computer support as an important future direction in the area of conflict resolution and negotiation is discussed, and results of pilot testing of the prototype are reported. (Contains 17…

Describes the use of the Z39.50 information retrieval protocol as the basis for Infocal, a read-only, client/server-based campus information system. Technical considerations in adapting the protocol to nonbibliographic data, including semantic modules, dynamic attribute sets, and dynamic record syntax, are described in detail. (Contains 11…

A text production model is considered as an instrument for researching the writing strategies of abstractors. Within this framework, abstracting is a subtype of the writer's activities, which are described in terms of text actions. A computer system can be constructed that evaluates and/or supports human text production. (Author/AEF)

Presents a case study of the implementation of a 2-year project designed to stimulate the use of an electronic mail system called BIZNET by 1,100 part-time MBA (Masters in Business Administration) students at Santa Clara University (California). Topics addressed include the institutional setting, the development of BIZNET, and system description,…
