    Abstract
    Summarizes some experiences of the application of the priciples and postulates of S.R. Ranganathan's General Theory of Knowledge Classification, incorporating the freely faceted approach and analytico synthetic methods, to the design and development of specialized databases, including indexing, user interfaces and retrieval. Enumerates some of the earlier instances of the facet method in machine based systems, beginning with Hollerith's punched card system for the data processing of the US Census. Elaborates on Ranganathan's holistic approach to information systems and services provided by his normative principles. Notes similarities between the design of databases and faceted classification systems. Examples from working systems are given to demonstrate the usefulness of selected canons and principles of classification and the analytico synthetic methodology to database design. The examples are mostly operational database systems developed using Unesco's Micro CDS-ISIS software

    Abstract
    The knowledge structures that form traditional library classification schemes hold great potential for improving resource description and discovery on the Internet and for organizing electronic document collections. The advantages of assigning subject tokens (classes) to documents from a scheme like the DDC system are well documented

    Abstract
    Dagobert Soergel opened the discussion by saying, "Users need our help to find and make sense of information." He said that he believes that classification can provide much of the support users need. He sees little distinction between the concept of a thesaurus and that of classification since both seek to provide structure for knowledge bases in order to facilitate information retrieval. Soergel's discussion of his concept of a multifunctional, multilingual thesaurus comprised the bulk of his presentation. This thesaurus would be a database of concepts, terms, and relationships which would include classification. In this context, classification has a much broader set of functions than it currently does in most American libraries where classification serves primarily as a method of shelf arrangement. The thesaurus Soergel envisions would lay out the semantic map of a field and could therefore be used as a learning tool or as a basis for research planning, or to assist users in clarifying terms and concepts. It could support indexing and searching and provide for the organization of knowledge for expert systems and other artificial intelligence applications. Among its other features, such a thesaurus could assist users in making sense of information by providing structured presentation of search results based on user needs and preferences, and it could enhance natural language processing capabilities such as automated indexing and abstracting and machine translation.

    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
    This volume deals with both theoretical and empirical research in classification and encompasses universal classification systems, special classification systems, thesauri and the place of classification in a broad spectrum of document and information systems. Papers fall into one or three major areas as follows: 1) general principles and policies 2) structure and logic in classification; and empirical investigation; classification in the design of various types of document/information systems. The papers originate from the ISCCR '91 conference and have been selected according to the following criteria: relevance to the conference theme; importance of the topic in the representation and organization of knowledge; quality; and originality in terms of potential contribution to research and new knowledge.

    Abstract
    The Wolverhampton Web Library (WWLib) is a WWW search engine that provides access to UK based information. The experimental version developed in 1995, was a success but highlighted the need for a much higher degree of automation. An interesting feature of the experimental WWLib was that it organised information according to DDC. Discusses the advantages of classification and describes the automatic classifier that is being developed in Java as part of the new, fully automated WWLib

    Abstract
    Thesauri-structured controlled vocabularies, designed for information retrieval-are compared with classification schemes developed for the arrangement of library materials and/or bibliographic records. The syndetic structure (BTs and NTs) within the alphabetic sequence of thesauri constitutes a hidden classification, but many thesauri include an explicit hierarchical display; some feature notation. The various structures and applications of thesauri are surveyed, with an emphasis on their increasing role in electronic information retrieval. The skills required for thesaurus construction are similar to those for the development of classification schemes. The distinction between these activities is expected to blur in the future.

    Abstract
    Potential uses for classification data in machine readable form and reasons for the development of a standard, the USMARC Format for Classification Data, which allows for classification data to interact with other USMARC bibliographic and authority data are discussed. The development, structure, content, and use of the standard is reviewed with implementation decisions for the Library of Congress Classification scheme noted. The author examines the implementation of USMARC classification at LC, the conversion of the schedules, and the functionality of the software being used. Problems in the effort are explored, and enhancements desired for the online classification system are considered.

    Abstract
    Ia McIlwaine, head of the Classification Research Group and editor of the UDC, noticed that the session's title invited crystal ball gazing, a talent she denied possessing. However, she admitted that she had asked the Classification Research Group to engage in such an exercise with her. The Group found, like the participants at the Allerton Institute were finding, that the contemplation of classification's future provided more questions than answers, but the questions were well worth considering. Her talk focused around a problem which originates in the difference between classifiers' uses and users' uses for classification systems. For users, who speak with the paraphrased self-confidence of Humpty Dumpty, a subject is a subject because they say it is. McIlwaine pointed out that this process of "saying" is at the heart of the users' needs which should be addressed by classification systems. Users use words to approach information systems and their associated classification systems. Classifiers need to recognize that this is the use to which their systems will be put. A body of users external to the classification process will make very different demands upon the system as compared to the users of the classification system who are also the creators of the system. Users desire information grouped for individual usefulness, and the groupings need to be according to words through which users can approach the system.

    Abstract
    This paper discusses constraints in knowledge organisation for information retrieval introduced by the difficulty of separating logical views of data, information, concepts and their relationships, from the physical means by which we seek to implement retrieval systems. A parallel is drawn between the move from enumerated to faceted classification and the emergence of relational database management systems to replace those adopting a hierarchical structure. This parallel suggests a convergence of ideas which have been, to a large extent, developed independently. The role of post-coordinated retrieval systems and thesauri is then examined before an interface design (HIBROWSE - a High resolution Interface for BROWsing and SEarching databases), is described which brings together the principles of faceted classification and increases the bandwidth of interaction through view-based searching.

    Abstract
    Argues that classification systems have an important role to play in knowledge organization in the new world electronic order. The natural language approach is not incompatible with the use of a classification system and classification has untapped potential as a multilingual switching language. Librarians must learn to present classification systems in a language understood by a general audience and promote them as general knowledge organization tools

    Abstract
    The study of faceted classification systems has primarily been directed towards application for precombined catalogues or bibliographies, not so much for use in post coordinated retrieval systems. Argues that faceted classification systems in some respects are superior to other techniques of on-line retrieval as far as facet and concept analysis is combined with an expressive notational system in order to guide a form of retrieval which will use Boolean operators (for combining the facets regardless of one special citation order) and truncation for retrieving hierarchically different sets of documents. This point of view is demonstrated by 2 examples. The 1st one uses a short classification system derived from B. Buchanan and the 2nd is built upon the classification system used by Library and Information Science Abstracts (LISA). Further discussion is concerned with some possible consequences which could be derived from a retrieval with PRECIS strings
    "Online retrieval" conjures up a very different mental image now than in 1991, the year this article was written, and the year Tim Berners-Lee first revealed the new hypertext system he called the World Wide Web. Gödert shows that truncation and Boolean logic, combined with notation from a faceted classification system, will be a powerful way of searching for information. It undoubtedly is, but no system built now would require a user searching for material on "nervous systems of bone fish" to enter "Fdd$ and Leaa$". This is worth reading for someone interested in seeing how searching and facets can go together, but the web has made this article quite out of date.

    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
    Subject based classification is an important part of information retrieval, and has a long history in libraries, where a subject taxonomy was used to determine the location of books on the shelves. We have been studying the notion of subject itself, in order to determine a formal ontology of subject for a large scale digital library card catalog system. Deep analysis reveals a lot of ambiguity regarding the usage of subjects in existing systems and terminology, and we attempt to formalize these notions into a single framework for representing it.

    Abstract
    There is every indication that classification systems which are international in their use, and free from the impact of national languages, will be given strong consideration as the choice for an information retrieval language in an automated environment. The aims of the Symposium were: to provide a forum for discussion of the problems and opportunities emerging from MARC records; to reconsider intellectual level as a significant determinant of information retrieval; and to explore the potential of the Dewey Decimal Classification and the Library of Congress Classification systems as information retrieval languages in an on-line environment.
