Abstract

Part of a special issue on hypertext and information retrieval. Conventional information retrieval systems provide little support for browsing. Browsing is the major method of searching in hypertext system but users can become disoriented even when browsing small information space. If hypertext is to be used to support browsing in bibliographic databases navigational assistance will be required. Examines the role of thesauri as navigational aids for subject domains of Bibliographic databases. Presents the design of an experimental hypertext-based browsing inference for a thesaurus and its implementation using a commercially available hypertext program. Examines strategies for linking the thesaurus to a database

Abstract

Explores the strengths and limitations of hypertext for the online presentation of thesauri used in information retrieval. Examines the ability of hypertext to support each of 3 common types of thesaurus display: graphic, alphabetical, and hierarchical. Presents a design for a hypertext-based hierarchical display that addresses many inadequacies of printed hierarchical displays. Ullustrates how the design might be implemented using a commercially available hypertext system. Considers issues related to the implementation and evaluation of hypertext-based thesauri
