Abstract
We view hypertext as an inherently dynamic concept to incorporate in the interface of dynamic information systems.What challenges does hypertext face in a constantly changing environment? In this paper, we discuss the benefitsand the problems we face in our research into hypertext-oriented decision support systems. Then we focus on a newhypertext construct beneficial to this domain: valuation links. Valuation links support the dynamic spreading ofcomputation via a well defined link traversal operation. We present two classes of such links: static and dynamic,and specify an algorithm for their traversal. We also show how these constructs can be used in sophisticated DSSenvironments.
