Integrates structured data and text using the unchanged, standard relational model. The performance of a parallel relational database system and the effect of query reduction on accuracy were tested, and it was found that queries can be reduced prior to their implementation without incurring significant loss in precision/recall. (AEF)

The paper describes a classification system for adaptive methods developed in the area of adaptive educational hypermedia based on four dimensions: What components of the educational system are adapted? To what features of the user and the current context does the system adapt? Why does the system adapt? How does the system get the necessary…

Complex computer and video games may provide a vehicle, based on appropriate theoretical concepts, to transform the educational landscape. Building on the original game object model (GOM) a new more detailed model is developed to support concepts that educational computer games should: be relevant, explorative, emotive, engaging, and include…

Instructional Design Expert (ID Expert) is a prototype instructional design expert system which supports the instructional design phase of instructional system development. It differs from other instructional design toolkits in that it is built using a knowledge engineering approach, and has been implemented as an expert system. The system…

This report describes the application of a shell expert system from the medical diagnostic system, Neomycin, to Caster, a diagnostic system for malfunctions in industrial sandcasting. This system was developed to test the hypothesis that starting with a well-developed classification procedure and a relational language for stating the…

Identifies weaknesses of conceptual modelling languages for the problem domain of information systems (IS) development. Outlines an approach called facet modelling of real-world problem domains to deal with the complexity of contemporary analysis problems. Shows how facet models can be defined and visualized; discusses facet modelling in relation…

Presents costs and benefits of document information systems as well as a design methodology. Highlights include the method of working, method of modelling, multiple data types, access structure and indexing, and a case study of the implementation of a document information system in the Netherlands. (Author/LRW)

Contains an excerpt from the author's landmark work about the way lay people think about technology and the language they use to express their thoughts. Discusses some of the fundamental differences between common conceptualizations of the way computers work and the way other machines and mechanisms work. (TB)

This article compares cognitive processing between natural and artificial language (AL) use and utilizes psycholinguistics for building a cognitive model of the AL user. Discussion covers observations concerning common ground, optimal design, collaborative processes, generalization, and incremental parallel production. Inquiries like this may lead…

Discusses the role that information resource management (IRM) plays in educational program-oriented budgeting (POB), and presents a theoretical IRM model. Highlights include design considerations for integrated data systems; database management systems (DBMS); and how POB data can be integrated to enhance its value and use within an educational…

Describes a computational model of the human process of generating text. The system design and generation process are discussed with particular attention to domain independence and cross language portability. The results of system tests are presented, the generator is evaluated with respect to current generators, and future directions are…

Describes ECAL (extended computer-assisted learning) which was designed to incorporate artificial intelligence ideas to extend traditional CAL tools. Intelligent tutoring systems are discussed; authoring tasks in CAL and intelligent computer-assisted instruction (ICAI) are described; and the general architecture of the system is explained. (8…

Provides a framework for examining the programs required to meet the challenges of information management education along five dimensions: area of study; faculty and school base; core programs; education and orientation of coprofessionals and managers; and management education and orientation. Approaches for improving the value of information…

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…

Based on previous research, this article describes an attempt to combine a traditional computer-based training (CBT) approach with intelligent computer-assisted instruction (ICAI) to create training materials. Hardware and software configuration of the Eurobench Workstation is described and courseware generation is discussed. (eight references)…
