Personnalisation de la distribution et de la présentation des informations des bases de vidéo interactive diffusées

Abstract : In this thesis we deal with the issues of the design and personalization of data-oriented interactive video applications (i.e. multimedia/hypermedia documents applications with predominance of audio and video data) in the emerging residential multimedia informatoin services (i. e. interactive television and second generation telematics) More specifically, we are concerned with the server-push information services (i.e. distributed dynamic and broadcast information sources) to be deployed in heteroyenous environments with shared ressources and destinated to users having different information needs and preferences. In this context, they are a lot of possible aspects to personalize. Here we focus on two particular related aspects : structure-based information filtering and personalization of contents presentation modalities. The techniques to achieve these personalization aspects are tightly related to the design of a given information source. Our approach to personalization is based on the definition of a conceptual data model, HB_Model, composed of : 1) a base model to represent documents organization and internal structure in video interactive sources, 2) a versionning model, HB_Versions, to represents documents contents with multiple alternative representation forms or modalities, and 3) a model for wiews definition, HB_Views, to represent relatively stable users information needs. Personalized information delivery from a given server - based on structure criteria - is archived by the materialization of individual users' views specifications using newly available information on this server. Personalization of contents representation modalitics is archived by the intentional specification of documents contents configuration in the form of a CSP (Constraint Satisfaction Problem) which reflects the constraints of the interaction and presentation contexts caracteristics on the choice of the presentation modality for each content and garantees the coherence of presentation modalities combinations. Finally, we show how our propositions articulate and fit into the architecture of a personalized, server-push interactive video information service.
