• UDC activities in Russia: a VINITI report

      Arskiy, Yurij M (UDC Consortium, 2008-12)
      VINITI is the publisher of UDC schedules in Russian language and the only publisher that still maintains, develops and publishes a full UDC edition. Much of VINITIâ s effort is put into research and development of the classification, user support and training. Being part of the Russian Academy of Science, VINITIâ s main strength as classification publisher comes from its team of scientists, researchers and subject specialists that work on the development and maintenance of the knowledge organization terminology. VINITI maintains a Russian UDC database and is also responsible for the alignment of the UDC with the Russian Rubricator for Science and Technology, the official scientific taxonomy that serves as a unified indexing language for information exchange in the fields of scientific research and technology.
    • UDC and folksonomies

      Šauperl, Alenka (UDC Consortium, 2009-12)
      Social tagging systems, known as ‘folksonomies’, represent an important part of web resource discovery as they enable free and unrestricted browsing through information space. Folksonomies consisting of subject designators (tags) assigned by users, however, have one important drawback: they do not express semantic relationships either hierarchical or associative between tags. As a consequence, the use of tags to browse information resources requires moving from one resource to another, based on coincidence and not on the pre-established meaningful or logical connections that may exist between related resources. We suggest that the semantic structure of the Universal Decimal Classification (UDC) may be used in complementing and supporting tag-based browsing. In this work, two specific questions were investigated: (1) Are terms used as tags in folksonomies included in the UDC? and (2) Which facets of UDC match the characteristics of documents or information objects that are tagged in folksonomies? A collection of the most popular tags from Amazon, LibraryThing, Delicious and 43Things was investigated. The universal nature of UDC was examined through the universality of topics and facets covering diverse human interests which are at the same time interconnected and form a rich and intricate semantic structure. The results suggest that UDC-supported folksonomies could be implemented in resource discovery, in particular in library portals and catalogues.
    • UDC and its use: a case study of libraries and information centres in Delhi

      Singh, K. P. (UDC Consortium, 2008-01)
      This paper explores the use of UDC in libraries and information centers of Delhi. The information presented here is part of the larger data set collected by the author while compiling the Delhi libraries web directory. The survey, conducted through library visits and questionnaires, shows that in Delhi there are sixty four libraries using various editions of UDC. These include libraries of Defense Research and Development Organization (DRDO), Council of Scientific and Industrial Research (CSIR), Indian Council of Agricultural Research (ICAR), as well as libraries of the Judiciary system situated in Delhi such as Supreme Courts of India, High Courts of Delhi and Districts courts of Delhi. Some libraries of national importance such as Indian Institute of Technology, National Agricultural Library, National Medical Library, National Science Library, are also using the UDC.

    • UDC as a non-disciplinary classification system for a high-school library

      Cousson, Philippe (UDC Consortium, 2009-12)
      The paper addresses issues in establishing a user-friendly systematic collection arrangement following a merger of two high school and college library collections classified according to UDC. In the way it was used, this scheme presented some weaknesses with respect to collection usage. Due to the disciplinary nature of UDC, subjects and phenomena are dispersed in the scheme according to the disciplines in which they are the subject of study. At the same time students in a school library often seek interdisciplinary subjects and need access to clusters of documents which according to UDC may be classed in several different knowledge areas. The author illustrates how this problem was resolved by re-arranging the collection according to phenomena. This was achieved by interpreting UDC numbers as if they represented specific phenomena. Thus, by superimposing some local indexing rules onto a disciplinary knowledge organization system it was possible to collocate interdisciplinary subjects under a single class number. Furthermore, by reversing subject numbers and form auxiliaries (atlases, dictionaries, textbooks etc.) which is an option envisaged in the design of UDC, documents were collocated in the way they are most frequently used by students. The author suggests that, in practice, one often needs to overcome the constraints of disciplinary classification and he discusses the approach used in his school library collection.
    • UDC at the BBC

      Alexander, Fran; Stickley, Kathryn; Buser, Vicky; Miller, Libby (UDC Consortium, 2010-12)
      The BBC Archive is one of the world’s largest multimedia archives, held in 27 locations across the UK. The Archive contains over 2 million items of TV and video, 300,000 hours of audio, 6 million still photographs, over 4 million items of sheet music, and over half-a-million documents and records. It is a working media library, fulfilling some 4,000 loans per week, as well as preserving content as part of the UK’s national cultural heritage. A team of cataloguers and media managers classify a selection of current content, as well as enhancing cataloguing and classification of legacy content. There are two major classification schemes used in the Archive, both numerical, and one based on UDC. Lonclass, based on UDC, was developed first, then Telclass, which is used by the Natural History Unit in Bristol. In addition, there are many and various controlled vocabularies that have been developed to tag content in the different nations (Scotland, Wales, and Northern Ireland) and the English regions.
    • UDC Biology Revision Project: First Stage: Class 59 Vertebrates

      Civallero, Edgardo; UDC Consortium (UDC Consortium, 2010-12)
      The paper presents and describes the work on the revision of the zoology of vertebrates, which is published in E&C 32 and introduced in UDC MRF 2010. This is the first stage of a larger project of revision, correction and update affecting all tables related to systematics (zoology, botany, microbiology and virology) to be undertaken from 2011-2013. The first part of the paper briefly introduces the current systems of classification of living and extinct beings, and explains how different perspectives with respect to the arrangement of biological entities have been reflected (or not) in the UDC schedules. The second part gives an overview of problems detected in UDC prior to this revision and explains solutions that were implemented in UDC MRF 2010 indicating tools and methods used in this work.
    • UDC Biology Revision Project: Second Stage: Class 58 Botany

      Civallero, Edgardo; UDC Consortium (UDC Consortium, 2011-12)
      This text is a brief update on the progress of the revision of biological systematics in UDC that has not had an overall revision for many decades. The first stage of the project, in 2010, included the revision of the taxonomy of vertebrates, and this was completed and published in Extensions and Corrections to the UDC - E&C, 32 (2010). The next stage, completed in 2011, was class 582 Systematic botany, published as the revised table in this issue - E&C, 33 (2011). In this paper, the author of the revised tables provides a brief overview of content organization and presentation in the new schedules and specific information about the revision of Botany.
    • UDC Editorial Workshop, The Hague, 21 September 2011: a report

      Davies, Sylvie; UDC Consortium (UDC Consortium, 2011-12)
      UDC Editorial Workshop is a meeting of the UDC Editors and UDC Advisory Board and invited guests. The 2011 workshop took place on 21 September 2011, in the Koninklijke Bibliotheek in The Hague and was attended by twenty participants. The focus of the workshop was on the structural issues of the UDC scheme, in particular with respect to the ongoing faceting of the scheme and the way in which this influences the UDC content revision process.
    • UDC implementation: from library shelves to a structured indexing language

      Slavic, Aida (IFLA, 2004)
      The UDC is attractive to different stakeholders across the information sector because of its wide-spread application, large vocabulary and availability in an electronic format. Modern information retrieval systems have the need but also the capacity to support flexible and interactive retrieval systems. The role of classification in such systems is to serve as an underlying knowledge structure that provides systematic subject organisation and thus complements the search using natural language terms. There are, however, specific requirements that must be satisfied in order to make efficient use of classification and these are not well known outside the library domain and are poorly implemented in library systems. This is especially the case for synthetic classifications, such as UDC, because its elements are meant to be manipulated by the system to fulfill different functions (a flexible systematic display, browsing or search purposes). This report summarizes the most important functionalities of the UDC that need to be taken into account during the implementation process. Important issues about the relation between the UDC schedules in electronic form - UDC Master Reference File and a classification tool (an authority file) that may be built on it, are highlighted. A better understanding of the UDC system's functionality may improve or facilitate its implementation and lower the costs of system maintenance which may be relevant for both prospective users and legacy systems.

      The Slovenian translation of the UDC version of MRF 2001 - in the online edition available at http://www.nuk.uni-lj.si/udk/ - was presented at the UDC Seminar in The Hague, in June 2007. In the autumn of 2008 it was updated according to the UDC MRF 2006, including changes approved from 2002 to 2006.
    • UDC in Czechia

      Balikova, Marie; Cordeiro, Maria Inês (UDC Consortium, 2007)
      UDC is widely used in all types of libraries in the Czech Republic (Czechia). The classification plays an important role in the National Library as well as the entire library information network. It is central to the subject authority file of the National Library of the Czech Republic (NL CR) and its bibliographic services. The author explains the importance and potential of UDC use online especially in a multilingual context and illustrates this with examples from the national union catalogue, the Czech Uniform Information Gateway (UIG), the Multilingual Subject Access to Library Catalogues (MSAC) system and the Multilingual Content Aggregation System (M-CAST) projects. The advantages of using UDC in improving precision and recall are explained using the M-CASt system.
    • UDC in India: use and problems

      Satija, Mohinder P; Guru Nanak Dev University, Amritsar - India (UDC Consortium The Hague, 2008-12)
      Dewey’s Decimal Classification was introduced in India in 1915 by Asa Don Dickinson (1876-1960), a student of Melvil Dewey, on his appointment as Librarian in Punjab University, Lahore. Soon after, India became its largest user of the system in Asia. It is, however, unknown when and how UDC was first used in India. The earliest reference to UDC can be found in Ranganathan’s classic Prolegomena to library classification (1937), wherein he made a comparative study of the then existing classification systems in order to derive some normative principles of classification,but more so to demonstrate the supremacy of his own system, Colon Classification (CC). Nevertheless, it is known that some libraries were using UDC by the early 1950s.

    • UDC in Lithuania

      Noreikiene, Dalia; "Martynas Mazvydas" National Library of Lithuania (UDC Consortium The Hague, 2008-12)
      The article provides a short overview of the history of the UDC use in Lithuania and current project of UDC translation in Lithuanian.
    • UDC in Lithuania

      Norekiene, Dalia (UDC Consortium, 2008-12)
      In 1991, the first UDC schedules in Lithuanian language were published as an abridged UDC edition adapted for Lithuanian public libraries. In the period 1992-1993 separate fascicles of complete Russian UDC tables continued to be translated, adapted and published for Lithuanian libraries. As the need for a standard Lithuanian edition has become more apparent, the Lithuanian National Library started preparation of the new edition in 1995. At the time of this report more than 64,000 classes of the UDC MRF database have been translated into Lithuanian; several volumes of the new Lithuanian edition have already been published and others are in preparation.
    • UDC in Slovenia

      Rifl, Boris; Rozman, Darija; Musek, Tine; Cordeiro, Maria Inês (UDC Consortium, 2007)
      In Slovenia, the majority of libraries use the Universal Decimal Classification (UDC). The authors give an overview of the extent of the use of classification in both open access and bibliographic control in their country. Since 1991 there have been no editions of the UDC published in the Slovenian language and this paper announces the change that occurred when two very important tools were made available to UDC users in 2006 and 2007 respectively. The new Slovenian translation of the UDC was produced by the National and University Library (NUL) in Ljubljana in 2007. This Web edition uses the original structure of the ISO 2709 file format which allows searching of UDC numbers (string searching and full text searching), searching UDC captions, notes, examples, etc. The tool has a user friendly web interface for browsing and navigating UDC schedules via hyperlinks, facilitating checking and selection of an appropriate class mark. At the same time a group of authors in the Slovenian National Library published a Slovenian UDC manual addressing the specific needs of Slovenian libraries and established practice in subject indexing. The manual is abundant with practical examples for both inexperienced and advanced users of UDC
    • UDC in subject gateways: experiment or opportunity?

      Slavic, Aida (2006)
      This is a preprint of a paper to be published in Knowledge Organization. The paper gives a short overview of the history of use of UDC in Internet subject gateways (SGs) with an English interface, from 1993 to 2006. There were in total, nine quality controlled SGs that were functional for shorter or longer periods of time. Their typology and functionality is described. Quality SGs have evolved and the role of classification has changed accordingly from supporting subject organization on the interface and automatic categorization of resources, towards supporting a semantic linking, control and vocabulary mapping between different indexing systems in subject hubs and federated SGs. In this period, many SGs ceased to exist and little information remains available regarding their status. SGs currently using UDC, for some part of their resource organization, do not use a UDC subject hierarchy at the interface and its role in resource indexing has become more difficult to observe. Since 2000, UDC has become more prevalent in East European SGs, portals and hubs, which are outside the scope of this research. This paper is an attempt to provide a record on this particular application of UDC and to offer some consideration of the changes in requirements when it comes to the use of library classification in resource discovery.
    • UDC in Ukraine 2009-2010: new developments

      Nabhan, Yulia (UDC Consortium, 2010-12)
      There are two main classification systems used in Ukraine, such as Universal Decimal Classification (UDC) and Library Bibliographic Classification (LBC). UDC is used mainly in libraries of higher education institutions, scientific, scientific-and-technical, medical, agricultural and other specialized libraries, information centres and publishing houses. The paper introduces recent developments (2009-2010 period) regarding UDC in Ukraine.
    • UDC Medical Sciences Project: Progress and Problems

      Williamson, Nancy; McIlwaine, I. C. (UDC Consortium, 2009-12)
      Phase 1 of the new class 61 Medical Sciences was completed early in 2009 and the work on Phase 2 is now well under way. In phase 1, a framework for the new class was established using the organization of facets provided in Class H of the Bliss Bibliographic Classification. Bliss terminology was used in the captions together with UDC notation and formatting as needed. Concepts and terms, the common auxiliaries, and classes related to medicine were used insofar as they were appropriate. There was heavy use of common auxiliary tables of general characteristics (Table 1k) -02 Properties, -04 Relations and Processes and -05 Persons as they became available. As needed, other tools were consulted including Medical Subject Headings (MeSH) and the World Health Organization’s International Classification of Diseases (ICD). At the end of Phase I the result was a framework for medicine which itself needed revision to be compatible with UDC. In Phase 2 the principal goal is to update the proposed Medical Sciences class to bring it into line with UDC as it exists today and to add new diseases and other terms which are covered in neither Bliss (1981) nor the present UDC 61 (which has not been revised for many years).
