in this paper, we present the step by step knowledge acquisition process by choosing a structured method through using a questionnaire as a knowledge acquisition tool. Here we want to depict the problem domain as, “how to evaluate teacher’s performance in higher education through the use of expert system technology”. The problem is how to acquire the specific knowledge for a selected problem ef...

Model-driven simulation can make the design and delivery of instruction more efficient and effective. We describe two computational models that support both the design and delivery of instruction. BEST (the Benchmarked Experiential System for Training) can guide experts through the space of domain problems during the knowledge engineering phase of instructional design; it can guide trainees thr...

Executives are experts in managing their business systems, much in the same way Formula One drivers are experts in driving their cars. However knowing the behaviour of cars doesn’t tell one how they are constructed and could be improved with new technology. The same holds true for Reengineering Business Systems through Information Technology. If management wishes to redefine the organisation, t...

A linear mixture of experts is used to combine three standard IR systems. The parameters for the mixture are determined automatically through training on document relevance assessments via optimization of a rank-order statistic which is empirically correlated with average precision. The mixture improves performance in some cases and degrades it in others, with the degradations possibly due to t...
