    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
    Conceptual Knowledge Markup Language (CKML), an application of XML, is a new standard being promoted for the specification of online conceptual knowledge (Kent and Shrivastava, 1998). CKML follows the philosophy of Conceptual Knowledge Processing (Wille, 1982), a principled approach to knowledge representation and data analysis, which advocates the development of methodologies and techniques to support people in their rational thinking, judgement and actions. CKML was developed and is being used in the WAVE networked information discovery and retrieval system (Kent and Neuss, 1994) as a standard for the specification of conceptual 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
    This paper describes the background underlying and the methods to be used in an investigation of use of the gopher protocol for browsing and searching for information via the Internet. Networked information resources are notoriously difficult to find; gopher is one attempt to facilitate the processes of organization and retrieval in that environment. Our project will design classification schemes based on traditional library models (i.e. Dewey and Library of Congress) and compare use of these to use of an existing gopher. We describe the project, the research questions, literature on related issues, the construction of the classification schemes, and the experimental methodology used

    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
    A fascinating, broad-ranging article about classification, knowledge, and how they relate. Hierarchies, trees, paradigms (a two-dimensional classification that can look something like a spreadsheet), and facets are covered, with descriptions of how they work and how they can be used for knowledge discovery and creation. Kwasnick outlines how to make a faceted classification: choose facets, develop facets, analyze entities using the facets, and make a citation order. Facets are useful for many reasons: they do not require complete knowledge of the entire body of material; they are hospitable, flexible, and expressive; they do not require a rigid background theory; they can mix theoretical structures and models; and they allow users to view things from many perspectives. Facets do have faults: it can be hard to pick the right ones; it is hard to show relations between them; and it is difficult to visualize them. The coverage of the other methods is equally thorough and there is much to consider for anyone putting a classification on the web.

    Abstract
    Modern fact databses contain abundant data classified through several classifications. Typically, users msut consult these classifications in separate manuals or files, thus making their effective use difficult. Contemporary database systems do little support deductive use of classifications. In this study we show how deductive data management techniques can be applied to the utilization of data value classifications. Computation of transitive class relationships is of primary importance here. We define a representation of classifications which supports transitive computation and present an operation-oriented deductive query language tailored for classification-based deductive information retrieval. The operations of this language are on the same abstraction level as relational algebra operations and can be integrated with these to form a powerful and flexible query language for deductive information retrieval. We define the integration of these operations and demonstrate the usefulness of the language in terms of several sample queries

    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
    For generations, libraries have facilitated access to information sources by the development and use of a wide range of appropriate organizational processes. Within a Web-based demonstration prototype, we have applied several established library procedures, principles and practices to enhance access to selected Internet resources in science and technology. In seeking to manage these sources, we have established defined collection, adopted an established library classification scheme as an organizational framework, and sought to stimulate the features and functions of a physical library collection and conventional reference sourcees. This paper describes the key components of this prototype, reviews research which supports its approach, and profiles suggested enhancements which could further facilitate identification, access and use of significant Internet and WWW resources

    Abstract
    Online displays of bibliographic records in call number order can serve various functions. A literature search showed no papers or books discussing this topic directly. Various displays from online catalogues available via the Internet were examined, as were displays sent to the author by colleagues. A number of the displays were uninformative to the extent that the identification of works associated with call numbers was difficult or impossible without follow-up searching of the individual bibliographic records. Other displays provided information where further searching of the database would not be required for most purposes. Displays noted ranged from displays with call numbers alone, with no bibliographic information, to records including main entry, title, statement of responsibility, place, publisher, and date. Suggestions of useful data elements to be included in displays of bibliographic records in call number order are made for the following functions: shelflisting, cataloguing, catalogue maintenance, reference, public searches, acquisition and collection development, and inventory control. Recommendations are made that the following data elements should be present in call number displays: entire call number as a sequencing element; main entry; entire title proper, and the date. Concern is expressed that the call number filing arrangement be that followed in traditional shelflists, and a suggestion is made that possible consensus on the placement of the data elements within a display be considered in the future

    Abstract
    Eine ganze Anzahl von Bibliotheken in Europa befaßt sich mit der Entwicklung von Internet Subject Gateways - einer Serviceleistung, die den Nutzern helfen soll, qualitativ hochwertige Internetquellen zu finden. Subject Gateways wie SOSIG (The Social Science Information Gateway) sind bereits seit einigen Jahren im Internet verfügbar und stellen eine Alternative zu Internet-Suchmaschinen wie AltaVista und Verzeichnissen wie Yahoo dar. Bezeichnenderweise stützen sich Subject Gateways auf die Fertigkeiten, Verfahrensweisen und Standards der internationalen Bibliothekswelt und wenden diese auf Informationen aus dem Internet an. Dieses Referat will daher betonen, daß Bibliothekare/innen idealerweise eine vorherrschende Rolle im Aufbau von Suchservices für Internetquellen spielen und daß Information Gateways eine Möglichkeit dafür darstellen. Es wird einige der Subject Gateway-Initiativen in Europa umreißen und die Werkzeuge und Technologien beschreiben, die vom Projekt DESIRE entwickelt wurden, um die Entwicklung neuer Gateways in anderen Ländern zu unterstützen. Es wird auch erörtert, wie IMesh, eine Gruppe für Gateways aus der ganzen Welt eine internationale Strategie für Gateways anstrebt und versucht, Standards zur Umsetzung dieses Projekts zu entwickeln

    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 'facet-space' approach for accessing document records organized by faceted classifications is described. The interface gives users detailed control over the facet display and it makes use of color to reduce the number of windows which need to be presented. The interface supports searching. A cluster analysis is described for organizing search return lists based on facets distances. The implementation is applied to 1381 summaries of computer science dissertations as organised by the ACM Computing Reviews classification system

    Abstract
    Describes the development by the Defence Metallurgical Research Laboratory, Hyderabad, India, of an expert system for classification of technical documents using the UDC schedule for metallurgy as knowledge base and the UDC classification rules as rule base. The scheme was modified from its enumerative structure to an analytico-synthetic structure which is best suited to such an expert system. Some benefits of the expert system are that: it interacts with the classifier making them conform to the route suggested by the classification scheme; it alerts the classifier to the minor variations in the scheme thus avoiding overlooking them; it leads to consistency in class number generation; and it ensures that the classifier has incorporated als the concepts of the subject in the class number, by leading him or her through all the groups, which is not possible in the manual scheme

    Abstract
    Ranganathan's canons, principles, and postulates can easily confuse readers, especially because he revised and added to them in various editions of his many books. The Classification Research Group, who drew on Ranganathan's work as their basis for classification theory but developed it in their own way, has never clearly organized all their equivalent canons and principles. In this article Spiteri gathers the fundamental rules from both systems and compares and contrasts them. She makes her own clearer set of principles for constructing facets, stating the subject of a document, and designing notation. Spiteri's "simplified model" is clear and understandable, but certainly not simplistic. The model does not include methods for making a faceted system, but will serve as a very useful guide in how to turn initial work into a rigorous classification. Highly recommended
