Abstract

Information retrieval functions in digital libraries have a different context from those which apply to searching commercial databases or OPACs. Different methods of browsing in this context are described, but the retrieval function should also include ordinary Boolean searching. Conversion of printed materials to electronic format using OCR can result in errors, which may cause problems for keyword searching. The n-gram method of approximate or fuzzy matching to reduce this problem is described

Abstract: In 1991 60,4% of Japanese university libraries had introduced computerized systems and 57,5% of these had computerized catalogues. In this context, discusses the following: subject searching in computerized catalogues; standardisation of OPACs, particularly as these are now available to a wide range of external users; and access to journal articles, especially in view of increasing journal purchase relative to books

Abstract: The development of the revised 9th ed. is described, giving examples of problem areas in the 8th ed. Individual sections are discussed. Although improvements have been made in notation, 'see references', clarification of relations between classes, supplementary tables etc., the are still areas requiring further work

Abstract

Description of an attempt to improve OPAC subject access at Kobe University Library using Nippon Decimal Classification, 8th ed. (NDC8). Examines the theoretical aspects of using a classification for subject searching, then explains the Kobe system. Using the NDC8 machine-readable data file, a database was created for the OPAC, incorporating class numbers and subject headings. Difficulties arise from subdivisions and the structure of NDC8 itself, but it is an important area for development

Abstract: The Nippon Decimal Classification (NDC) system, extensively used in Japanese libraries, was devised in 1929. It is difficult to use NDC to classify world literature, such as fiction in English by non American, non British writers. This is not necessarily straightforward in other classification schemes but a survey of 40 Japanese university libraries, of which 24 responded, showed remarkable inconsistencies in the treatment of 22 world literature authors. NDC clearly needs updating to deal with this problem
