A key advantage of hypermedia systems such as the Web is that the user is able to navigate through the information space in a non-linear fashion. He can explore the interlinked documents according to his own interests and insights, instead of being confined to the rigid, linear structure of, e.g., pages in a book. A downside, however, is that this navigational freedom entails the risk of disorientation, especially in a gigantic hypertext such as the Web. This paper presents a context-based navigation paradigm for the Web and reconciles navigational freedom with a measure of linear guidance to prevent the user from becoming disoriented. For that purpose, "conventional" navigation along static links is complemented by run-time generated guided tours, which are derived dynamically from the context of a user's information requirements.
