ePaper: A personalized mobile newspaper

This paper describes ePaper, a research prototype system of a personalized newspaper on a mobile reading device. The ePaper aggregates content (i.e., news items) from various news providers, classifies the news items according to concepts from a news domain ontology, and delivers an electronic newspaper to each subscribed user (reader). The system personalizes the content of the newspaper according to the userʹs profiles and preferences by applying ontological content-based and collaborative filtering algorithms. The userʹs profile is updated implicitly and dynamically, based on the tracking of their reading. Beyond personalization, the ePaper can also provide the user with a “standard edition” of a selected newspaper, as well as browsing capabilities in a repository of news items. The layout of the newspaper is adapted to the specifications of the reading device and to the userʹs preferences. In this overview paper, we highlight the main research challenges involved in the development of ePaper and describe how we addressed them.
