Abstract
In order to personalize information for a nomadic user, it is necessary to consider on the one hand, the context of use (which provides in particular a description of the conditions temporal, spatial, hardware, etc. under which users accesses the Information Systems), and on the other hand, user preferences which aim at expressing what the user would like to obtain from the system considering different aspects such as functionalities, content, display, etc.). We propose an approach generating a Contextual User Profile (CUP), profile which is made up only of the user preferences selected considering the current context of use. This approach proposes formalism for three different types of user preferences (activity, result and display). Additionally, this approach defines the Contextual Matching Algorithm which generates the CUP based on user preferences and on the context of use.
