Abstract

Describes an approach to indexing which seeks to eliminate the shortcoming of the representation of information in existing bibliographic catalogues: Subject Access Project (SAP) indexing which has been used successfully at Lund University and elsewhere. Existing catalogue records have been enriched with terms selected from lists of contents and indexes in books thus facilitating access to specific parts of documents and smaller semantic entites such as chapter titles, subject titles and data in graphic or tabulated form available in a wide range of publications

SAP indexing for exploring the full thematic context of books and for access to smaller semantic entites

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: Considers the potential of providing enhanced content indexing of document records either by natural language or PRECIS controlled vocabulary in order to provide more effective subject access to OPACs. Considers multilingual access OPACs. Controlled vocabulary is the best option for the latter in the short terms

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

Abstract

The paper examines the developmentss that have taken place during the last decade with respect to the provision of intellectual subject access in information databases storage. The principles of the SAP indexing methodology are outlined and exemplified, leading to a discussion of the consequences for the conception of the physical 'document' versus 'semantic entities' as the basic constructs for storage and multi-dimensional representation of subject matter. Finally, the paper analyzes the impact of very recent technologies which make achievable such access conceptions and mechanisms

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
