Adaptive Navigation Support in Educational Hypermedia on the World Wide Web
Adaptive navigation support is a new direction of research within the area of adaptive and user-model based interfaces. The goal of adaptive navigation support (ANS) techniques is to help users find an appropriate path in the learning and information space by adapting link presentation to the goals, knowledge, and other characteristics of an individual user. This paper briefly reviews several methods of adaptive navigation support and discusses their applicability in WWW context. We suggest some reasonably simple but effective ANS methods for Web-based systems: history-based, knowledge-based and prerequisite-based adaptive annotation. We describe of two developing Web-based educational systems, InterBook and KBNS-WEST to demonstrate the manner in which these key methods could be incorporated into a Web-based educational system and to provide a working example of ANS methodology.
