Personalized, interactive news on the Web

Abstract.

We present Krakatoa Chronicle, an interactive, personalized newspaper on the World Wide Web implemented as a Java applet. The newspaper is similar in appearance to newspapers in the real world, with a multi-column layout and justified text. At the same time, it provides various interaction techniques for browsing the content of articles, giving relevance feedback, and dynamically changing layout. As users interact with the system, individual ‘user profiles’ are built up at the webserver site. These are used to tailor the newspaper's content and layout to each user's declared and inferred preferences. The system allows for a balancing of personal and community interests, allowing the user to navigate through a space of newspapers corresponding to a range of viewpoints.
