Abstract
Two interfaces are described for navigating large collections of document and book records. An Online Public Access Catalog interface uses a classification hierarchy to facilitate browsing and searching. The system has been implemented and currently runs with over 50,000 book records. Interface widgets allow the hierarchy to be displayed and traversed easily. For example, the Book Shelf dynamically updates itself to reflect searches and attribute selections. A second interface, not yet fully implemented, allows access to the ACM Computing Reviews classification. By browsing a graphic structure such as a classification hierarchy or term network, the user can select or negate terms to incrementally enlarge or refine the query. A number of systems have been proposed that utilise this type of interface: Allen [1] allows users to traverse sections of a classification hierarchy that are adjacent to documents retrieved by a search; Doyle [6] discusses a graph-based interactive browsing environment; Croft [4] extends Doyle's termbased graph with vertices and edges representing individual documents and their degrees of similarity to each other; Frei and Jauslin [7] use tree structures to represent both system command menus and document indexing structures; and Godin [10] and Pedersen [16] model a collection's conceptual structure with termdocument lattices.
