Node Re-Usability in Structured Hypertext Systems

Abstract

When the size of a graph-based hyperdocument exceeds a certain limit, the graph structure gets complicated and causes navigation and document management problems. A simple solution for this problem is the structuring ofthe hyperdocument into several smaller units. In this approach each unit contains nodes that share common properties and their link structures. Srnuller. more manageable networks (called webs) which have their own, less complex graph structures are the result. In this paper we propose a model for hypertext systems which allows hyperclocument structuring using webs. The model demonstrates node re-usability which becomes essential as it is verylikely that the smaller units created will share nodes. The implementation details of a hypertext authoring system, HypAS, based on the proposel model is also provided.
