- Abstract
- Experimental evidence suggests that enhancing the subject content of OPAC records can improve retrieval performance. This is based on the use of natural language index terms derived from the table of contents and back-of-the-book index of documents. The research reported here investigates the alternative approach of translating these natural language terms into controlled vocabulary. Subject queries were collected by interview at the catalogue, and indexing of the queries demonstrated the impressive ability of PRECIS, and to a lesser extent LCSH, to represent users' information needs. DDC performed poorly in this respect. The assumption was made that an index language adequately specific to represent users' queries should be adequate to represent document contents. Searches were carried out on three test databases, and both natural language and PRECIS enhancement of MARC records increased the number of relevant documents found, with PRECIS showing the better performance. However, with weak stemming the advantage of PRECIS was lost. Consideration must also be given to the potential advantages of controlled vocabulary, over and above basic retrieval performance measures

- Der Beitrag beschäftigt sich mit der Anwendung eines Verfahrens zur automatischen Indexierung deutschsprachiger Texte in Bibliotheken. Die Arbeitsweise des Verfahrens und seine Entwicklung innerhalb der von der Deutschen Forschungsgemeinschaft geförderte und an der ULB Düsseldorf gemeinsam mit der Fachrichtung Informationswissenschaft der Universität des Saarlandes durchgeführten Projekte MILOS I, MILOS II und KASCADE werden geschildert. Die Ergebnisse von Retrievaltests belegen die Tauglichkeit des Verfahrens für den Einsatz in Bibliotheken. Aufsetzend auf diesen Ergebnissen werden Perspektiven für die bibliothekarische Sacherschließung im Hinblick auf den Einsatz von automatischen Verfahren entworfen

- Abstract
- As librarians plan ahead to make subject enhancements available to online searchers in various possible file locations and formats, they may want to base their decisions on implications for online searching. This paper explores some of these implications with respect to unique and misleading terminology in tables of contents, Choice abstracts, and reviews from Computing reviews for thirty-six books on information and computer science chosen from the 1987 issues of Choice. It also discusses possible interacting functions in the search process served by these subject enhancements, assigned LCSH, and book title terminology

- Abstract
- Contents notes can improve online access to works containing essays, short stories, and significantly titles chapters. Few records in bibliographic utilities include contents notes. The OCLC PRISM service may provide an opportunity to cooperatively build a contents-enriched database. This paper discusses some issues related to the creation of enhanced records and their display in online cataloges. It also describes one library's efforts to add contents notes lically and to participate in an anticipated OCLC pilot project

- Abstract
- To enhance descriptions, cataloguers can add 'enriching' words or phrases to titles, or introduce content-enriched access features to aid subject-based research. Additional and natural language subject headings designed to support, though not replace, controlled language headings can result in enhanced indexing. Analytical cataloguing and double indexing are 2 other means by which readers can gian access to additional bibliographic data. Also examines how online research tool effectiveness can be enhanced by a system of automatic links between descriptors

- Abstract
- This report describes an experiment in subject enhancement conducted at an academic research library. Subjects and contents notes were added to online catalog records for a group of previously uncirculated social science essay collections, and circulation was monitored over one academic year. A control group, plus a third group with added contents notes but no extra subjects, were also monitored. Results showed an improvement in recorded use for the subject-enhanced titles, but not for titles that only had added contents notes. The effects of browsing, keyword searching, and OPAC display are discussed

- Abstract
- Since Dec 86, the Australian Defence Force Academy (ADFA) library has been enriching bibliographic records by adding terms from either the contents pages or indexes of books. 40.000 records are now enriched, representing about 25% coverage of the ADFA database of 210.000 titles. Evaluates the retrieval effectiveness of the enriched data in an OPAC, in comparison with title and LCSH, using 90 topics from 6 different subject areas

- Abstract
- Shortened and revised version of a paper presented during an Education Librarian's Group session at the Under One Umbrella Two Conference, organized by the Library Association in Manchester, 9-11 Jul 93. With the possibility of free text searching and easy access to CD-ROM databases, users often do not realise that subject searching is enhanced by familiarity with the controlled vocabulary underlying the indexing system of the database. Discusses the construction of information retrieval thesauri, the problems of terminology and how the use of thesauri can make searching more effective, using education thesauri as examples
