Context-Awareness in User Modelling: Requirements Analysis for a Case-Based Reasoning Application

The paper describes an approach of using the case-based reasoning methodology in context-aware systems. It elaborates how this technique can be applied to generate recommendations based on the contexts of users respectively objects especially in a mobile scenario. By combining case-based reasoning methodology and context awareness a new and powerful way of modelling and reasoning from contexts emerges. Using cases to enclose contexts will enhance the possibilities to compare contexts, determine certain values of context-similarities, and reflect this information in the process of generating recommendations. Furthermore, this contribution tries to show how the users' behaviour can be learnt in a case-based fashion and how the users' way of thinking can be simulated.
