Evaluation-oriented information provision is a function performed by many systems that serve as personal assistants, advisors, or sales assistants. Five general tasks are distinguished which need to be addressed by such systems. For each task, tech niques employed in a sample of systems are dis cussed, and it is shown how the lessons learned from these… (More)
For the last two decades, configuration systems relying on AI techniques have successfully been applied in industrial environments. These systems support the configuration of complex products and services in shorter time with fewer errors and, therefore, reduce the costs of a mass-customization business model. The European Union–funded project entitled… (More)
Recent advances in user modeling technology have brought within reach the goal of having systems adapt to temporary limitations of the user's available time and working memory capacity. We first summarize empirical research by ourselves and others that sheds light on the causes and consequences of these (continually changing) resource limitations. We then… (More)
The modeling of noncooperative dialogs, as opposed to dialogs in which the goals of the participants coincide, presents novel challenges to a pragmatically oriented dialog system. PRACMA models noncooperative sales dialogs. In the role of the potential buyer of a used car, the system tries to arrive at a realistic evaluation of the unknown car in spite of… (More)
Situationally determined limitations in users' " resources " (e.g., time and working memory) constitute an increasingly important challenge to adaptive interfaces—one which does not yield easily to straightforward solutions. This article gives an overview of a research program that emphasizes empirically based understanding of this problem and the use of an… (More)
This paper emphasizes on the enhancement of web-based selling technology for complex products. The approach of the EC-funded CAWICOMS 1 project is twofold: provision of technologies both for customer-adaptive Web-interfaces for the configuration of mass-customized products as well as for the integration of configuration systems along the supply-chain.… (More)
For the last two decades product configurators relying on Artificial Intelligence techniques have been successfully applied in industrial environments. These systems support the configuration of complex products and services in shorter time with fewer errors and therefore reduce costs of a mass-customization business model.
