Vers une approche d’adaptation dynamique et temps-réel du contenu informationnel d’une interface utilisateur dans un environnement ubiquitaire

Abstract : Ubiquitous environments are often considered highly dynamic environments and the contextual information can change at runtime. User interface should provide the right information for the right person at the right time. Certainly, such objective can be achieved only when we deduce the realtime user’s requirements in terms of information and present this information to the user according to his current context of use. The specific goal of our research is to improve the adaptation process while improving models at runtime. A fixed model cannot handle the high dynamic in such an environment. The model can progress and change its structure to better deduce the user’s requirements. Selecting the appropriate model is not that easy. To address this problem, adaptation strategies will be based on evolutionary models. Such models can be created while integrating progressively a range of elementary actions or undergo modifications and changes as the result of interactions with the user and through reinterpretations of existing models stored by the acquisition of preceding knowledge. Our approach takes advantage of OWL-S’s properties in order to describe the dynamic functioning of Petri-nets models. We formulate a Petri-nets based elementary action by using an OWL-S atomic process. And then, we progressively compose a set of elementary actions to formulate a Petri-nets based activity. The presented method lays a sound foundation for dynamic composition of Petri-nets based modeling.
