Title

Structural analysis of hypertexts identifying hierarchies and useful metrics

Source

ACM transactions on information systems. 10(1992) no.2, S.142-180

Year

1992

Abstract

In many hypertext systems authors are encouraged to create hierachical structures, but when writing, the hierarchy is lost because of the inclusion of cross-reference links. Looks at ways of recovering lost hierarchies and finding new ones, offering authors different views of the same hypertext. Identifies properties of the hypertext document. Develops multiple metrics including compactness and stratum - compactness indicates the intrinsic connectedness of the hypertext, and stratum reveals to what degree the hypertext is organised so that some nodes must be read before others. Uses several exosting hypertexts to illustrate the benefits of each technique. The collection of techniques provides a multifaceted view of the hypertext, which should allow authors to reduce undesired structured complexity and create documents that readers can transverse more easily
