- Abstract
- The author collected information about tables of content and index terms in 125 books borrowed by patrons in a medium-sized academic library. To learn how useful the term would be as subject terms in a library catalog, he determined which of these terms were the same as the words used by the patrons to describe the books. For 72,4% of the books assigned LCSH, the patron's term matched the LCheading. The patron's term matched the table of contents term for (1,3% of the books with tables of contents. If the catalog had included terms from the tables of contents and the indexes in addition to the LCSH, the success rate would have been 97,3%. One problem in using terms from books in a library catalog is that many books lack indexes and/or tables of context

- 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

- Abstract
- Contents enhancement of catalog records may increase access to books in collections and aid in effective resource sharing by providing more detailed descriptions about library holdings in the catalog. A sample of monographs in San Diego State Univ. Library was studied to determine the extent to which information in books from parts of the collection could be represented better by content notes, and to determine how much of this information has subject or analytical applications. The study revealed that approximately 23% of the books contain discrete content information not already represented in catalog records that could be added. Of those, 52% would be citation-based enhancements and 48% would be subject-based. Nearly 65% would require fewer than 25 enhancements, with an average of 8.03 enhancements per book for the total population

- Abstract
- In 1986, all titles added to the collection at the Australian Defence Force Academy Library, are processed through their OPAC via a subject enhancement procedure (ESP). The procedure used for subject enhancement is based on the techniques developed by P.A. Atherton and B. Settel during the Subject Access Project at Syracuse Univ., 1977. Terms are selected from contents pages or the index of the book, depending on whether the terms are content bearing, and whether the terms refer to 5 or more pages of text. This results in the addition of an average of 73 words or 20 phrases to each MARC record. The terms are keyed into the MARC field 653 using in house modifications of the library's URICA system

- 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
- Describes the Intelligent Literature Search Assistant (ILSA) which demonstrates the possibilities of a fully automated cataloguing workbench in an object orientated environment. Although developed with OPAC users in mind, it can be very useful to cataloguers in aiding both classification and subject heading access. Also describes work done at the University of Strathclyde in the area of machine learning and knowledge based systems, the Structured Information Management: Processing and Retrieval project (SIMPR). Advocates the use of uncontrolled vocabulary headings in conjunction with systems like ILSA, a layered approach rather than direct first point access, in order to make subject cataloguing easier and more relevant and the subject catalogue more useful to others

- 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
