Overview:

With the dawn of Ajax the capabilities of tracking user behavior multiplied. The same holds for the capabilities of adapting the user interface in a Web browser. To provide meaningful adaptation, the events, context and elements of an Ajaxified Portal must be given meaning. This paper shows the use of ontologies as a model for user-related context and portal-related content. Content-related concepts are used to annotate Ajax widgets to associate them with meaning. As a user navigates a portal and fires events related to the widgets, a semantically rich user model is built, enabling suitable adaptation. Both the user model and the adaptation are based on ontologies and logic rules.
