Paragraph‐based access to full‐text documents using a hypertext system Available to Purchase

This paper considers the use of a hypertext system, GUIDE, for paragraph‐based searching in full‐text documents. Searching can be effected in GUIDE using both a conventional, word‐based approach and using the inter‐textual linkage facilities. The effectiveness of these retrieval techniques are evaluated by means of searches of three full‐text documents for which relevance data are available. The results of the searches are compared with those obtained from use of a nearest neighbour retrieval system that has been developed for the ranking of paragraphs within full‐text documents. The comparison suggests that the linkage facilities in hypertext do not provide a very cost‐effective mechanism for paragraph‐based retrieval.
