- Abstract
- Indexing terms supplied by authors can increase subject control of their documents. The terms can be used in the creation of indexes, abstracts, and other devices for information retrieval in the special library. An examination of the American Mathematical Society author indexing program suggests that contributions of authors enhance indexing efforts of editors

- 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
- Content
- 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
- From a logical point of view, an OPAC is an inventory with indexes. Inventories can be accumulated and the indexes merged. However, in most merged catalogues not all documents have the same subject indexing and a number of documents are indexed by more than one system. In practice, a merged catalogue also contains descriptions without subject indexing. To augment the situation four methods are used: searching with title keywords, mapping and switching, acceptance of descriptions indexed in a given way only, and »citation pearl growing«. The last method uses all available subject indicators by using subject indicators present in relevant descriptions found by already known indicators. This method can also be of help in mapping and switching.

- Abstract
- This paper analyzes proposals for augmenting library bibliographic records for improved subject searching in online catalogs. Possible fields for enrichment are described and their likely value assessed. The assessment determines that the main value of enriched records would be to provide access to parts of books. The paper presents arguments for and against adding book content indexing to the online catalog and analyzes the feasibility of eleven alternatives for providing such information

- 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

- 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

- Abstract
- This article describes our efforts in supporting information retrieval from OCR degraded text. In particular, we report our approach to an automatic cataloging and searching contest for books in multiple languages. In this contest, 500 books in English, German, French, and Italian published during the 1770s to 1970s are scanned into images and OCRed to digital text. The goal is to use only automatic ways to extract information for sophisticated searching. We adopted the vector space retrieval model, an n-gram indexing method, and a special weighting scheme to tackle this problem. Although the performance by this approach is slightly inferior to the best approach, which is mainly based on regular expression match, one advantage of our approach is that it is less language dependent and less layout sensitive, thus is readily applicable to other languages and document collections. Problems of OCR text retrieval for some Asian languages are also discussed in this article, and solutions are suggested

- Abstract
- Traditional subject cataloguing hampers subject retrieval in central catalogues, because of the lack of a common indexing and retrieval language in these catalogues. This study investigates the possibilities to use the various individual subject access systems, present in the catalogues, for subject access. A search procedure based on 'citation pearl growing' and 'user relevance feedback', which can be applied in a public access interface to central data bases, has been developed. From an experiment it can be concluded, that automated expert assistance, provided with a search strategy, will improve search response for unexperienced searchers. It reduces the number of zero-hits and increases the number of relevant items retrieved
