- Abstract
- This paper examines issues relating to the use of the Dewey Decimal Classification (DDC) in a future development of view-based searching to Online Public Access Catalogues (OPAC). View-based searching systems, exercising the principles of fully faceted classification techniques for both bibliographic and corporate database retrieval applications, are now being applied to utilise Dewey concept hierarchies in a University OPAC. Issues of efficiency and effectiveness in the evolving organisation and classification of information within libraries are examined to explain why fully faceted classification schemes have yet to realise their full potential in libraries. The key to their application in OPACs lies in the use of faceted classification as pre-coordinated indexing and abandoning the single dimension relative ordering of books on shelves. The need to maintain a single relative physical position on a bookshelf is the major source of complexity in classification. Extensive latent benefits will be realised when systematic subject arrangements, providing alternative views onto OPACs, are coupled to view-based browser and search techniques. Time and effort will be saved, and effectiveness increased, as rapid access is provided to the most appropriate information to satisfy the needs of the user. A future for Dewey Classification divorced from its decimal notation is anticipated

- Abstract
- Compares and evaluates the functional capabilities and interface characteristics of OPACs from the user oriented perspective, using a systematic framework. OPACs of OhioLINK and its 16 member libraries are the object of the investigation. The interfaces used 6 system software but showed a variety of features in access to OPACs, operational control, access points, search formulation control, and user assistance. Interface design alternatives are identified and qualitatively analyzed

- Abstract
- Presents a brief, critical review of LISA PLaus: the CD-ROM database version of LISA and which includes the database of Current Research in Library and Information Science (CRLIS). The review covers the DOS version only, as it appeared in the Summer 1996 CD-ROM, noting that the Windows version was planned for the future. Points to the way LISA has found its mark, if not its fortune, in LISA Plus and notes its strengths, including: ideal suitability for current awareness in library and information science (LIS); massive and convenient consolidation of the published LIS literature; and massive increase in coverage from 7.900 abstracts in 1993 to over 12.000 currently. Criticizes certain features of LISA Plus, notably: the OPTI-Ware search interface; the combination of 2 databases (LISA and CRLIS) in a single, searchable database; and certain unexpected effects caused by the building of the Subject and Free Text indexes. Points particularly to great lack of consistency in the indexes and the indexing (faults that were fully rectified by a complete overhaul of the data in Summer 1996). Notes that LISA Plus is the first port of call for both information researchers and information science students. The Windows version of LISA Plus was launched in Spring 1997

- Abstract
- Decribes the BookHouse, a system for the retrieval and indexing of fiction and non fiction literature developed for public and school libraries though cooperation between library and information science professionals. Discusses 3 aspects of the system: domain characteristic; task analysis; and user characteristics. Outlines the framework underlying the collection of field data with special emphasis on the work involved in transforming the empirical field studies of user behaviour in the library into computer system specifications and subsequent design of a retrieval system providing subject access to fiction. Describes a few of the many indexing policies, rules and practices which evolved for concept identification and book descriptions as well as the functionality and associated displays of the system for supporting the retrieval and indexing of fiction

- Abstract
- Reports results of study, undertaken at the Project Whistlestop Web site, Missouri University at Columbia to examine the indexing and retrieval rates of 5 WWW search engines: InfoSeek; Excite; Yahoo; Lycos and AltaVista. Character strings were planted in the Project Whistlestop Web site and daily searches were performed for 6 weeks. The HTML tag was indexed in 4 of the 5 search engines and problems encountered include insufficient and inconsistent indexing

- Abstract
- Digital libraries of geo-spatial multimedia content are currently deficient in providing fuzzy, concept-based retrieval mechanisms to users. The main challenge is that indexing and thesaurus creation are extremely labor-intensive processes for text documents and especially for images. Recently, 800.000 declassified staellite photographs were made available by the US Geological Survey. Additionally, millions of satellite and aerial photographs are archived in national and local map libraries. Such enormous collections make human indexing and thesaurus generation methods impossible to utilize. In this article we propose a scalable method to automatically generate visual thesauri of large collections of geo-spatial media using fuzzy, unsupervised machine-learning techniques

- Abstract
- The application of classification schemes and thesauri to improve online information retrieval can be traced back to the beginnings of online searching itself, but the true potential for using knowledge structures in the user interface has yet to be realized. View-based searching seeks to exploit the classified arrangements in thesauri and existing classification schemes to improve the performance of such systems. HIBROWSE for EMBASE is a system which demonstrates the power of applying an approach to information retrieval which is strongly related to faceted classification. It does this by employing a point a click user interface with mutually constraining views utilising knowledge structure hierarchies for both query specification and the presentation of results. The relevance of this approach to library OPACs is discussed in the context of the digital library, concluding that out legacy of research in classification and indexing is more relevant than ever in the design of systems to cope with the problems of information access
