UDC in Czechia

Balikova, Marie January 2007 (has links)
Paper submission to this archive is arranged with the author by the editor of the proceedings. For further information contact the editor Maria Ines Cordeiro <mariaines.cordeiro@gmail.com> or Aida Slavic (aida@acorweb.net) / 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.

Building a faceted classification for the humanities: principles and procedures

Broughton, Vanda, Slavic, Aida January 2007 (has links)
This is a preprint to be published in Journal of Documentation. The paper provides an overview of principles and procedures involved in creating a faceted classification scheme for use in resource discovery in an online environment. Facet analysis provides an established scientific methodology for the conceptual organization of a subject field, and the structuring of an associated classification or controlled vocabulary. This paper explains how that methodology was applied to the humanities in the FATKS project, where the objective was to explore the potential of facet analytical theory for creating a controlled vocabulary for the humanities, and to establish the requirements of a faceted classification appropriate to an online environment. A detailed faceted vocabulary was developed for two areas of the humanities within a broader facet framework for the whole of knowledge. Research issues included how to create a data model which made the faceted structure explicit and machine-readable and provided for its further development and use. In order to support easy facet combination in indexing, and facet searching and browsing on the interface, faceted classification requires a formalized data structure and an appropriate tool for its management. The conceptual framework of a faceted system proper can be applied satisfactorily to humanities, and fully integrated within a vocabulary management system. The procedures described in this paper are concerned only with the structuring of the classification, and do not extend to indexing, retrieval and application issues. Many stakeholders in the domain of resource discovery consider developing their own classification system and supporting tools. The methods described in this paper may clarify the process of building a faceted classification and may provide some useful ideas with respect to the vocabulary maintenance tool.

Maintenance of the Universal Decimal Classification: overview of the past and preparations for the future

Slavic, Aida, Cordeiro, Maria Inês, Riesthuis, Gerhard 06 1900 (has links)
The paper highlights some aspects of the UDC management policy for 2007 and onwards. Following an overview of the long history of modernization of the classification, which started in the 1960s and has influenced the scheme's revision and development since 1990, major changes and policies from the recent history of the UDC revision are summarized. The perspective of the new editorial team, established in 2007, is presented. The new policy focuses on the improved organization and efficiency of editorial work and the improvement of UDC products.

Visual Universal Decimal Classification?

Van der Linden, Erik-Jan, Van Wijk, Jerke J. January 2007 (has links)
The authors presents a tool developed by the Dutch company Magna View that enables the visual representation of the content of the UDC Master Reference File (UDC MRF). The tool contains a pre-processed UDC MRF and allows visualization of, for instance, hierarchy levels, number of classes within a hierarchy and provides an overview of UDC number distribution across all fields of knowledge. The tool is aimed at users and developers who work with and utilize the UDC MRF and can benefit from different kinds of classification data representation.

When More is Better: A Counter-Narrative Regarding Keyword and Subject Retrieval in Digitized Diaries

Knott Malone, Cheryl January 2007 (has links)
Many commercial full-text databases and digital libraries provide keyword and preferred-term (subject) indexing, but few allow participatory tagging of content by users or provide ontologies in support of natural language information retrieval. Consequently, keyword and subject searching strategies still matter. But keyword searching, because it can yield results high in recall and low in precision, is often seen as a beginner's strategy best replaced by subject searching using authoritative headings and descriptors. In certain circumstance explored in this essay, keyword searching may be quite effective in and of itself for retrieving digitized primary sources for the study of history.

Better consistency of the UDC system moving Medicine from section 61 to section 4

Benito, Miguel January 2007 (has links)
Over 45 years ago it was decided to move the class 4 for Language to the section 8 together with Literature. Since then class 4 has not been used. A recent master thesis at the school of librarianship in Boras , â UDC, A Proposal to Basic Class 4â by Fredrik Hultqvist, (Magisteruppsats; 2006:39) proved the possibility of moving Medicine from the section 61 to the empty class 4. This is not a new idea, but has never been implemented. Reasons are given to support this proposal, based on the need to find a better collocation of the subject while at the same time providing a solution for shorter notations.

The Classification of Psychology: A Case Study in the Classification of a Knowledge Field.

Hjørland, Birger January 1998 (has links)
Different approaches to the classification of a knowledge field include empiristic, rationalistic, historicist, and pragmatic methods. The article demonstrates how these different methods have been applied to the classification of psychology. It shows how basic epistemological assumptions have formed the different approaches to psychology during the 20th century. The progress in the understanding of basic philosophical questions is decisive both for the development of a knowledge field and as the point of departure of classification. Applies the theoretical principles developed in a brief analysis of some concrete classification systems, including the one used by PsycINFO/Psychological Abstracts. Also briefly discusses the role of classification in modern information retrieval.

A Classification of Scientific Models

Coleman, Anita Sundaram 07 1900 (has links)
This presentation at the Seventh ISKO Conference in Granada, Spain, highlights the important ideas behind the paper, A Classification of Models that is available in the Conference Proceedings. It provides a succinct definition of scientific models and identifies the underlying premises and promises of knowledge structures and classification pinciples for organizing these complex objects and intellectual constructs. Facets of scientific models are listed and described. Smiraglia's definition of works is used along with facet analysis theory and findings about science learning skills.

Forty-five numbers for snow: a brief introduction to the UDC for Polar libraries

Gilbert, Mark, Lane, Heather 12 1900 (has links)
This paper discusses the development of the Polar UDC. It examines some elements of the UDC specific to the Polar context, in particular the geographical auxiliary schedule. Some future plans for the implementation of UDC in a library and also in a museum context are outlined.

Image Access, the Semantic Gap, and Social Tagging as a Paradigm Shift

Jorgensen, Corinne January 2007 (has links)
The recent phenomenon of "social tagging" or "distributed indexing" raises a number of questions regarding long-held beliefs and practices of the classification and indexing community. This workshop paper covers several of these issues, such as locus of authority, control, and meaning, and suggests we may be observing the emergence of a new paradigm of knowledge organization.
