Abstract:
This paper describes the development and application of visualisation
techniques for users to access and explore information in a digital library
effectively and intuitively. Salient semantic structures and citation
patterns are extracted from several collections of documents, including the
ACM SIGCHI Conference Proceedings (1995-1997) and ACM Hypertext Conference
Proceedings (1987-1998), using Latent Semantic Indexing and Pathfinder
Network Scaling. The unique spatial metaphor leads to a natural combination
of search and navigation within the same semantic space in a 3-dimensional
virtual world. Author co-citation patterns are visualised through a number
of author co-citation maps in attempts to reveal the structure of the
hypertext, including an overall co-citation map of 367 authors and three
periodical maps. These maps highlight predominant research areas in the
field. This approach provides a means for transcending the boundaries of
collections of documents and visualising more profound patterns in terms of
semantic structures and co-citation networks. (C) 1999 Elsevier Science
