A Homogenous Interaction Platform for Navigation and Search in and from Open Hypertext Systems

In response to the challenge of open hypertext systems allowing access to heterogeneous information resources in the world-wide commercial and scientific information market, we propose a hypertext system model and architecture based on typed objects and links making possible semantically controlled access to information units within the hypertext, as well as to the outside information systems world. We concentrate particularly on a common interaction platform by describing the different browser types of the Constance Hypertext System (KHS), and describe in more detail various different navigation techniques and term-based retrieval methods thus furthering a productive partnership between information retrieval and hypertext.
