the use of cluster hierarchies in hypertext information retrieval
The graph-traversal approach to hypertext information retrieval is a conceptualization of hypertext in which the structural aspects of the nodes are emphasized. A user navigates through such hypertext systems by evaluating the semantics associated with links between nodes as well as the information contained in nodes. [Fris88] In this paper we describe an hierarchical structure which effectively supports the graphical traversal of a document collection in a hypertext system. We provide an overview of an interactive browser based on cluster hierarchies. Initial results obtained from the use of the browser in an experimental hypertext retrieval system are presented.
