Personalized presentation in web-based information systems

Large information spaces and complex functionality of contemporary systems together with the advent of the Semantic Web are big challenges for the design of simple yet powerful user interfaces. The complex nature of systems thus requires the use of several presentation, personalization and user modeling methods and techniques to address the growing needs and requirements of both users and systems. We present a design of an architecture for the personalized presentation layer of a web-based information system that employs a set of interconnected software components implemented as autonomous software tools for presentation, personalization and user modeling to support features such as navigation support and different views on the presented data, acquisition and evaluation of user characteristics and user adaptation and personalization. The feasibility of our design is evaluated by its realization in the labor market application domain.
