Profiling nomadic users considering preferences and context of use

In order to adapt information for a nomadic user equipped with a Mobile Device (MD), an Information System (IS) must take into consideration data that deals with the context of use and user preferences. Data about context of use provides in particular a description of the conditions (temporal, spatial, hardware, etc.) under which users accesses the IS. Data about user preferences aims at expressing what the user would like to obtain from the system considering different aspects (functionalities, content, display, etc.). In this paper, we propose a Contextual User Profile (CUP) which is made up only of the user preferences which can be satisfied considering the current context of use. We describe the process for generation of the CUP. An example illustrating our proposition is given. We also give the main elements for the design and implementation of a tool supporting our approach.
