In search of the unknown user: indexing, hypertext and the world wide web

David Ellis, Nigel Ford, Jonathan Furner
1998 Journal of Documentation  
For the purposes of this article, the indexing of information is interpreted as the pre-processing of information in order to enable its retrieval.  ...  In the following three sections, we discuss the application of indexing functions to document collections of three specific types: (1) 'conventional' text databases; (2) hypertext databases; and (3) the  ...  The thesaurus mechanism can also provide support for the browsing of index terms in a hypertext.  ...

A methodology for the automatic construction of a hypertext for information retrieval

Maristella Agosti, Fabio Crestani
1993 Proceedings of the 1993 ACM/SIGAPP symposium on Applied computing states of the art and practice - SAC '93  
The hypertext tool can be used for querying processing, as an automatic tool of query expansion, and for browsing, enabling the user to query and move through the IR data using different levels of abstraction  ...  This schema can be implemented by means of a hypertext tool using a set of automatic techniques for the identification of nodes and links.  ...  Considerations on the Design of an IR Hypertext An IR hypertext is a document base which allows access to documents mainly by browsing.  ...
