Title

¬The next generation of online public access catalogs : a new look at subject access using hypermedia

Source

Cataloging and classification quarterly. 13(1991) nos.3/4, S.103-132

Year

1991

Abstract

Current online catalogs have problems providing reasonable subject access, often resulting in searches with too few or too many hits. These problems can be improved by enhancing MARC records, building semantic networks through cross-references, and linking subject headings to classification numbers. This paper describes a pilot project to design a hypertext search engine using these principles

Dieser Beitrag enthält beispielsweise die Zahlen, daß 30% der Recherchen bei 0 Treffern landen, daß bei den verbleibenden 70% die durchschnittliche Trefferzahl bei 170 liegt, daß Benutzer durchschnittlich aber nur 7 Treffer genauer ansehen
