    Abstract
    The human natural ability to store and process images and speech provides clues for improving access to online information. The principles underpinning the maps people use in their minds can be applied to maps that can be presented at the user interface to online systems. Traditional classification organizes information into structured hierarchies and simplifies the search problem, but has serious limitations. Discusses the prospects for improving access to online information through the application of dynamic faceted classification. Presents a glimpse into the navigation of n-dimensional information space for future library OPACs using a modified DDC

    Abstract
    Describes the coming together of 2 independent user interface softwares for improving access to databases: MenUSE (Menu-based User Search Engine) and HIBROWSE (High Resolution Interface for Database Specific BROWsing and SEarching). MenUSE was developed for searching bibliographic databases whilst HIBROWSE is a front end for searching information stored on structured relational database management systems. Combining these 2 approaches affords users much greater access capabilities than is possible using traditional information retrieval systems. Describes the power of HIBROWSE in the context of EPOQUE (the European Parliament Online QUEry system) and the INSPEC database

    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

    Abstract
    Reviews research which aims to improve the ways in which documents are presented to the user within the MenUSE (Menu based User Search Engine) search intermediary system. MenUSE is an advanced intermediary system for end user searching of bibliographic databases originating in CANSEARCH, a prototype intermediary system that used an expert systems approach to generate searches in cancer therapy related information retrieval from MEDLINE. In particular it investigates ways in which the order of presentation of documents can be made more effective. Discusses alternative schemes for document reordering, the main emphasis being on the provision of relevance ranking where the most relevant documents are presented to the user first. Examines the feasibility of incorporating such ranking techniques into MenUSE and compares 3 algorithms which simulate collection frequency ranking on a remote bibliographic database host using Boolean searching. Concludes that the CIRT algorithm offers the best performance. Proposes a design for an enhancement to the MenUSE system which will be the subject of user testing to verify the effectiveness of ranking in MenUSE

    Abstract
    This paper presents a description and initial results of an evaluation of EuroMenUSE for the MAC, a system which offers an alternative mode of access to EPOQUE, the document database of the European Parliament. Subjects with a professional interest in European Parliament business, but with no prior knowledge of information retrieval systems, were able to search EPOQUE using EuroMenUSE for the Mac. These end-users achieved better retrieval results than similar subjects using the current Guided Search mode in use at the Parliament. They also performed better than subjects knowledgeable in information retrieval, but who had less subject knowledge, using the SIMBAD Common Command Language interface, the mode of access used by professional documentalists in the Parliament and other European Union Institutions

    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
    The physical organisation of items on library shelves using any classification scheme is inevitable a compromise. The best efforts to achieve an arrangement that is helpful to users will be thwarted by the multifaceted nature of these items and the specific needs of the user and the library. Items on a particular subject will be scattered throughout the library building(s) across disciplines, by physical form, by frequency of use and whether and for how long they may be borrowed. Even thought he rich information content of multifaceted items may be represented in the notation, the items required by a user will be scattered across library shelves when the item is placed in a single relative location. This paper explores these issues uisng examples from a University Library classified using the DDC. The electronic context of the library OPAC can transcend the constraints imposed by the predominantly physical nature of library collections, yet the current use of classification schemes in on-line systems retains many of these limitations. Examples of such systems applying DDC on the WWW are discussed and compared with a system that seeks to use DDC in what is called view-based searching. The interface and the resulting browsing and searching capability of a view-based OPAC are described. Ways in which subject access to library collections can be improved and disciplinary scatter resolved by assigning multiple class number to items and exploiting the rich Dewey structure in a faceted form are discussed. It is suggested that the informative power of visual classificatory structures at the search interface will be beneficial to the broader learning experience of the user. The paper concludes that the application of classification schemes in electronic interfaces should not be bound by the the physical constraints that no longer apply in an electronic context but be exploited to provide a complete, flexible and individual interface as determined by the needs of each user

    Abstract
    The scatter of items dealing with similar concepts through the physical library is a consequence of a classification process that produces a single notation to enable relative location. Compromises must be made to place an item where it is most appropriate for a given user community. No such compromise is needed with a digital library where the item can be considered to occupy a very large number of relative locations, as befits the needs of the user. Interfaces to these digital libraries can reuse the knowledge structures of their physical counterparts yet still address the problem of scatter. View-based searching is an approach that takes advantage of the knowledge structures but addresses the problem of scatter by applying a facetted approach to information retrieval. This paper describes the most recent developments in the implementation of a view-based searching system for a University Library OPAC. The user interface exploits the knowledge structures in the Dewey Decimal Classification Scheme (DDC) in navigable views with implicit Boolean searching. DDC classifies multifaceted items by building a single relative code from components. These codes may already have been combined in the schedules or be built according to well-documented instructions. Rules can be applied to decode these numbers to provide codes for each additional facet. To enhance the retrieval power of the view-based searching system, multiple facet codes are being extracted through decomposition from single Dewey Class Codes. This paper presents the results of applying automatic decomposition in respect of Geographic Area and the creation of a view (by Geographic Area) for the full collection of over 250,000 library items. This is the first step in demonstrating how the problem of scatter of subject matter across the disciplines of the Dewey Decimal Classification and the physical library collection can be addressed through the use of facets and view-based searching
