    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 interfaculty centre of Bologna University began 2 years ago a project to 'translate' UDC codes into a user friendly thesaurus, with the object of creating an accurate, easy to use tool for online researches, especially those relating to periodical titles. The UDC numerical codes have been linked by a method based on synonyms to a series of corresponding verbal indices which express in natural language the concepts expressed by the codes. Thus researchers can retrieve information not only through UDC codes but also through their analogous verbal descriptors. Describes the progress of the UDC project so far, and some problems encountered

    Abstract
    Edited version of a report to the Australian Library and Information Association on the Conference on classification theory in the computer age, Albany, New York, 18-19 Nov 88, and on the meeting of the Dewey Editorial Policy Committee which preceded it. The focus of the Editorial Policy Committee Meeting lay in the following areas: browsing; potential for improved subject access; system design; potential conflict between shelf location and information retrieval; and users. At the Conference on classification theory in the computer age the following papers were presented: Applications of artificial intelligence to bibliographic classification, by Irene Travis; Automation and classification, By Elaine Svenonious; Subject classification and language processing for retrieval in large data bases, by Diana Scott; Implications for information processing, by Carol Mandel; and implications for information science education, by Richard Halsey.

    Abstract
    Am 29. und 30. Oktober 2009 fand in der Königlichen Bibliothek in Den Haag das zweite internationale UDC-Seminar zum Thema "Classification at a Crossroad" statt. Organisiert wurde diese Konferenz - wie auch die erste Konferenz dieser Art im Jahr 2007 - vom UDC-Konsortium (UDCC). Im Mittelpunkt der diesjährigen Veranstaltung stand die Erschließung des World Wide Web unter besserer Nutzung von Klassifikationen (im Besonderen natürlich der UDC), einschließlich benutzerfreundlicher Repräsentationen von Informationen und Wissen. Standards, neue Technologien und Dienste, semantische Suche und der multilinguale Zugriff spielten ebenfalls eine Rolle. 135 Teilnehmer aus 35 Ländern waren dazu nach Den Haag gekommen. Das Programm umfasste mit 22 Vorträgen aus 14 verschiedenen Ländern eine breite Palette, wobei Großbritannien mit fünf Beiträgen am stärksten vertreten war. Die Tagesschwerpunkte wurden an beiden Konferenztagen durch die Eröffnungsvorträge gesetzt, die dann in insgesamt sechs thematischen Sitzungen weiter vertieft wurden.

    Abstract
    The ETH library has been using the UDC for the past twenty-five years and yet most of the users had almost never taken a single notice about it. The query in today's NEBIS-OPAC (former ETHICS) is based on verbal search with three-lingual descriptors and corresponding related search-terms including e.g. synonyma as well as user-friendly expressions from scientific journals - scientific jargon - to facilitate the dialog with OPAC. A single UDC number, standing behind these descriptors, connects them to the related document-titles, regardless of language. Thus the user actually works with the UDC, without realizing it. This paper describes the experience with this OPAC and the work behind it.

    Abstract
    In 2001, a group of information architects involved in designing websites, and knowledge management specialists involved in creating access to corporate knowledge bases appeared to have re-discovered facet analysis and faceted classification. These groups have been instrumental in creating new and different ways of handling digital content of the Internet. Some of these practitioners explicitly use the forms and language of facet analysis and faceted classification, while others seem to do so implicitly. Following a brief overview of the work and discussions on facets and faceted classification in recent years, we focus on our observations about new information resources which seem more in line with the Fourth law of Library Science ("Save the time of the reader") than most library OPACs today. These new developments on the Internet point to a partial grasp of a disciplined approach to subject access. This is where Ranganathan and Neelameghan's approach needs to be reviewed for the new audience of information system designers. A report on the work undertaken by us forms a principal part of this paper.

    "Am 16. August 2005 fand in Oslo im Rahmen der heurigen IFLA-Konferenz das alljährliche Treffen der DDC-Übersetzer und der weltweiten DeweyAnwender-Institutionen (Nationalbibliotheken, Ersteller von Nationalbibliografien) statt. Die im Sommer 2005 bereits abgeschlossene deutsche Übersetzung wird in der Druckfassung Ende des Jahres in 4 Bänden vorliegen, beim K. G. Saur Verlag in München erscheinen (ISBN 3-598-11651-9) und 2006 vom ebenfalls erstmals ins Deutsche übersetzten DDC-Lehrbuch (ISBN 3-598-11748-5) begleitet. Pläne für neu startende Übersetzungen der DDC 22 gibt es für folgende Sprachen: Arabisch (mit der wachsenden Notwendigkeit, Klasse 200 Religion zu revidieren), Französisch (es erschien zuletzt eine neue Kurzausgabe 14, nun werden eine vierbändige Druckausgabe und eine frz. Webversion anvisiert), Schwedisch, Vietnamesisch (hierfür wird eine an die Sprache und Schrift angepasste Version des deutschen Übersetzungstools zum Einsatz kommen).
    Allgemein DDC 22 ist im Gegensatz zu den früheren Neuauflagen der Standard Edition eine Ausgabe ohne generelle Überarbeitung einer gesamten Klasse. Sie enthält jedoch zahlreiche Änderungen und Expansionen in fast allen Disziplinen und in vielen Hilfstafeln. Es erschien auch eine Sonderausgabe der Klasse 200, Religion. In der aktuellen Kurzausgabe der DDC 22 (14, aus 2004) sind all diese Neuerungen berücksichtigt. Auch die elektronische Version exisitiert in einer vollständigen (WebDewey) und in einer KurzVariante (Abridged WebDewey) und ist immer auf dem jüngsten Stand der Klassifikation. Ein Tutorial für die Nutzung von WebDewey steht unter www.oclc.org /dewey/ resourcesitutorial zur Verfügung. Der Index enthält in dieser elektronischen Fassung weit mehr zusammengesetzte Notationen und verbale Sucheinstiege (resultierend aus den Titeldaten des "WorldCat") als die Druckausgabe, sowie Mappings zu den aktuellsten Normdatensätzen aus LCSH und McSH. Aktuell Die personelle Zusammensetzung des EPC (Editorial Policy Committee) hat sich im letzten Jahr verändert. Dieses oberste Gremium der DDC hat Prioritäten für den aktuellen Arbeitsplan festgelegt. Es wurde vereinbart, größere Änderungsvorhaben via Dewey-Website künftig wie in einem Stellungnahmeverfahren zur fachlichen Diskussion zu stellen. www.oclc.org/dewey/discussion/."

    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
    By providing the means for systematic arrangement, library classification has been used for centuries to organise document collections. The development of systems such as DDC, LCC a,d UDC, made classification sophisticated enough to be used both for the systematic arrangement of a collection and for information retrieval through the use of classified catalogues. Relatively short alphanumeric classification indexes are able to indicate quite sophisticated concepts, helping to overcome language barriers. With the advent of library automation, their role in the document retrieval process has become less important, in comparison with retrieval by natural language

    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
    New forms of man-machine interaction are becoming available that have great power for the delivery of information. But the scales of speed and capacity on which the computing machines operate demand new thoughts as to how information can be stored and retrieved. The objective of the discussion in this paper is to argue for a combination of natural-language processing and subject classification to be able to meet the demands

    Footnote
    AHUJA and SATIJA (Relevance of Ranganathan's Classification Theory in the Age of Digital Libraries) note that traditional bibliographic classification systems have been applied in the digital environment with only limited success. They find that the "inherent flexibility of electronic manipulation of documents or their surrogates should allow a more organic approach to allocation of new subjects and appropriate linkages between subject hierarchies." (p. 18). Ahija and Satija also suggest that it is necessary to shift from a "subject" focus to a "need" focus when applying classification theory in the digital environment. They find Ranganathan's framework applicable in the digital environment. Although Ranganathan's focus is "subject oriented and hence emphasise the hierarchical and linear relationships" (p. 26), his framework "can be successfully adopted with certain modifications ... in the digital environment." (p. 26). SHAH and KUMAR (Model for System Unification of Geographical Schedules (Space Isolates)) report an a plan to develop a single schedule for geographical Subdivision that could be used across all classification systems. The authors argue that this is needed in order to facilitate interoperability in the digital environment. SAN SEGUNDO MANUEL (The Representation of Knowledge as a Symbolization of Productive Electronic Information) distills different approaches and definitions of the term "representation" as it relates to representation of knowledge in the library and information science literature and field. SHARADA (Linguistic and Document Classification: Paradigmatic Merger Possibilities) suggests the development of a universal indexing language. The foundation for the universal indexing language is Chomsky's Minimalist Program and Ranganathan's analytico-synthetic classification theory; Acording to the author, based an these approaches, it "should not be a problem" (p. 62) to develop a universal indexing language.

    Abstract
    The construction and updating of indexing languages depend on the organization of their hierarchical structures in order to determine the classification of related terms and, above all, to allow a constant updating of vocabulary, a condition for knowledge evolution. The elaboration of an indexing language for online catalogs of libraries' networks is important considering the diversity and specificity of knowledge areas. From this perspective, the present paper reports on the work of a team of catalogers and researchers engaged in the construction of a hierarchical structure of an indexing language for an online catalog of a university library's network. The work on hierarchical structures began by defining the categories and subcategories that form the indexing language macrostructure by using the parameters of the Library of Congress Subject Headings , the National Library Terminology and the Vocabulary of the University of São Paulo Library's system. Throughout the stages of the elaboration process of the macrostructure, difficulties and improvements were observed and discussed. The results enabled the assessment of the hierarchical structures of the languages used in the organization of the superordinate and subordinate terms, which has contributed to the systematization of operational procedures contained in an indexing language manual for online catalogs of libraries.
