- Abstract
- The paper will give a short outline of the project DDC German. The project is not limited to a mere translation of DDC 22, but aims at the implementation of Dewey in the library networks of the German-language countries. Use of DDC mainly for retrieval purposes, not for shelving, leads to certain new aspects in classifying with Dewey which are described in detail and presented together with the German web service Melvil. Based an the German experience of cooperation and data exchange in the field of verbal indexing the paper develops some ideas an future Dewey cooperation between European and American libraries.

- Abstract
- The Library of Congress Classification (LCC), originally designed for classifying the Library's own collection, is now used in a wide range of libraries, both in the United States and abroad. This entry recounts its history and development from its genesis to the present time, leading up to an explanation of LCC structure, tables, and notation. It then considers the system's potential for wider application in the online age, through speculation on using LCC as a tool for (a) partitioning large files; (b) generating domain-specific taxonomies; and (c) integrating classification and controlled subject terms for improved retrieval in the online public access catalog (OPAC) and the Internet. Finally, analyzing both its strong and relatively weak features, it addresses the question of whether in its current state LCC is in all respects ready for playing such roles

- Abstract
- Die Dewey-Dezimalklassifikation (DDC) ist Ende 2003 in der 22. Ausgabe der Standard Edition auf Englisch erschienen und wird genau zwei Jahre später nun auch auf Deutsch veröffentlicht. Nach Übersetzungen ins Französische, Italienische, Russische und Spanische ist unter Beteiligung der drei deutschsprachigen Länder und mit Unterstützung durch die Deutsche Forschungsgemeinschaft die Voraussetzung dafür geschaffen worden, dass diese international weit verbreitete Klassifikation auch in Deutschland, Österreich und der Schweiz heimisch werden kann. Die hier vorgelegten Übersichten, die die drei obersten Ebenen oder 1 000 Klassen der DDC umfassen, ermöglichen einen Einblick in die Gliederung der gesamten Klassifikation und sind in dieser Form für Bibliotheken und wissenschaftliche Einrichtungen frei verfügbar, während die tieferen Ebenen der DDC durch das Urheberrecht geschützt sind. Die vollständige Ausgabe der DDC 22 Deutsch erscheint 2005 im Verlag K. G. Saur. Mit dem Webservice Melvil bietet Die Deutsche Bibliothek ab Januar 2006 eine deutsche Version von WebDewey an, ergänzt um ein Recherchetool für das Retrieval DDC-erschlossener Daten. Die DDC 22 ist von einer an der Fachhochschule Köln angesiedelten Arbeitsgruppe ins Deutsche übersetzt worden, unterstützt von einemTeam von Fachreferentinnen und Fachreferenten an zahlreichen Bibliotheken des deutschen Sprachraums und fachlich beraten von der Expertengruppe DDC Deutsch. Die organisatorische Leitung des Projekts DDC Deutsch lag bei Der Deutschen Bibliothek als federführendem Mitglied des Konsortiums DDC Deutsch. Ab 2006 wird die Deutsche Nationalbibliografie vollständige DDC-Notationen mitliefern, bereits seit Bibliografiejahrgang 2004 folgen die Sachgruppen der Deutschen Nationalbibliografie einer auf den beiden obersten Ebenen der DDC basierenden Gliederung. Die hier vorgelegte Übersetzung der DDC wurde mit der Herausgeberin der DDC, Joan Mitchell (OCLC, Dublin/Ohio) und ihren Mitherausgebern an der Library of Congress abgestimmt, denen wir für ihre Unterstützung und Beratung herzlich danken. Die kurze Einführung in die Dewey-Dezimalklassifikation, die hier folgt, stellt das gesamte System der DDC vor, das mit seinen Haupt- und Hilfstafeln mehr als 60 000 Klassen umfasst. Die Möglichkeiten zur Erschließung differenzierterThemen gehen daher weit über die hier vorgelegten obersten Klassen der DDC hinaus und berücksichtigen viele moderne Teildisziplinen, die man in den Übersichten vielleicht vermisst. Bei der Verwendung der Übersichten ist zu beachten, dass aus drucktechnischen Gründen in einigen Fällen Klassen nur verkürzt wiedergegeben werden können und nur durch ihre Position innerhalb einer Folge von Klassen genau zu verstehen sind. Daher sollten für die Erschließung auch die vollständigen Klassenbenennungen herangezogen werden, die unter www.ddc-deutsch.de im Netz zur Verfügung stehen.

- Abstract
- The paper will look into different patterns of facet analysis used in the UDC schedules and how these affect the scheme presentation, the underlying data structure and the management of the classification scheme. From the very beginning, UDC was designed to represent the universe of knowledge as an integral whole allowing for subjects/concepts from all fields of knowledge to be combined, linked and the nature of their relationships made explicit. In Otlet's original design, the emphasis for his new type of classification was on the coordination of classmarks at the point of searching, i.e., post-coordination, which he firmly rooted in an expressive notational system. While some UDC classes exhibit various patterns of facet analytical theory proper, others, although used in an analytico-synthetic fashion, follow less canonical structural patterns. The authors highlight the lack of connection made throughout the various stages of UDC restructuring between: a) theoretical requirements of an overarching facet analytical theory as a founding principle guiding the construction of schedules; and, b) practical requirements for an analytico-synthetic classification in terms of notational presentation and data structure that enables its use in indexing and retrieval, as well as its management online.

- Abstract
- Analytico-synthetic and faceted classifications, such as Universal Decimal Classification (UDC) provide facilities to express pre-coordinated subject statements using syntactic relations. In this case, the relevance, in the process of UDC-based information retrieval, can be determined by extracting the meaning of the classmarks as precisely as is possible. The central question here is how the identification mentioned above can be supported by automatic means and an analysis of the structure of complex classmarks appears to be an obvious requirement. Many bibliographic sources contain complex UDC classmarks which are stored as simple text strings and on which it is very difficult to perform any meaningful information discovery. The paper presents results from a phase of ongoing research focused on developing a new platform-independent, machine-processable data format capable of representing the whole syntactic structure of the composite UDC numbers to support their further automatic processing. An algorithm that can produce the representation of the numbers in such a format directly from their designations has also been developed and implemented. The research also includes implementing conversion methods to provide outputs that can be employed by other software directly and, as a service, make them available for other software. The paper provides an overview of the solutions developed and implemented since 2015 and outlines future research plans.

- Abstract
- In 2003, OCLC published Dewey Decimal Classification and Relative Index, Edition 22 (DDC 22), in print and Web versions. The changes and updates in the new edition reflect a modern view of knowledge structures and address the general needs of Dewey users. The content of DDC 22 has been shaped by a number of social, geopolitical, and technical trends. The World Wide Web has provided a vehicle for more frequent distribution of updates to the DDC, and a medium for direct communication with Dewey users around the world. In addition to updating the system itself, other strategies are needed to accommodate the needs of the global Dewey user community. Translation of the system is one approach; another is mapping. Mapping terminology to the DDC is a strategy for supporting effective local implementation of the system while maintaining the internal cohesiveness of the DDC. This paper explores the usefulness of mapping terminology from English-language general subject headings lists produced outside the U.S.

- Abstract
- The advent of the Internet has intensified problems of classification and nomenclature in a range of disciplines that have been the concern of librarians and scientists for over a century. Biology and Medicine are selected as examples, and the work of specialists both in scientific systematics and taxonomy and in bibliographic classification is examined in order to suggest some solutions to current difficulties in information retrieval

- Abstract
- In the Internet information space, advanced information retrieval (IR) methods and automatic text processing are used in conjunction with traditional knowledge organization systems (KOS). New information technology provides a platform for better KOS publishing, exploitation and sharing both for human and machine use. Networked KOS services are now being planned and developed as powerful tools for resource discovery. They will enable automatic contextualisation, interpretation and query matching to different indexing languages. The Semantic Web promises to be an environment in which the quality of semantic relationships in bibliographic classification systems can be fully exploited. Their use in the networked environment is, however, limited by the fact that they are not prepared or made available for advanced machine processing. The UDC was chosen for this research because of its widespread use and its long-term presence in online information retrieval systems. It was also the first system to be used for the automatic classification of Internet resources, and the first to be made available as a classification tool on the Web. The objective of this research is to establish the advantages of using UDC for information retrieval in a networked environment, to highlight the problems of automation and classification exchange, and to offer possible solutions. The first research question was is there enough evidence of the use of classification on the Internet to justify further development with this particular environment in mind? The second question is what are the automation requirements for the full exploitation of UDC and its exchange? The third question is which areas are in need of improvement and what specific recommendations can be made for implementing the UDC in a networked environment? A summary of changes required in the management and development of the UDC to facilitate its full adaptation for future use is drawn from this analysis.

- Abstract
- Dewey Decimal Classification and Relative Index, Edition 22 (DDC 22) will be issued simultaneously in print and web versions in July 2003. The new edition is the first full print update to the Dewey Decimal Classification system in seven years-it includes several significant updates and many new numbers and topics. DDC 22 also features some fundamental structural changes that have been introduced with the goals of promoting classifier efficiency and improving the DDC for use in a variety of applications in the web environment. Most importantly, the content of the new edition has been shaped by the needs and recommendations of Dewey users around the world. The worldwide user community has an important role in shaping the future of the DDC.

- Abstract
- A work in progress. An analysis of the handling of the domain "environmental science" in three universal classification schemes. Attention is given to problems of primary location, interdisciplinarity, degree of scatter, tenninology and structure of the domain. 1. Introduction Many traditional tools for organizing and providing access to recorded knowledge have become increasingly inadequate in responding to the changing requirements for effective organization and retrieval. The universal classification systems have been primary targets for criticism. In varying degrees they have been proven too rigid and somewhat limited as tools of modern knowledge organization. These inadequacies can be attributed to several significant factors - the changing nature of knowledge itself, the emergence of new domains, the realignment of old ones, and the development of very large databases. Also, more and more, as new technologies become available, there is increasing emphasis an the retrieval of facts as opposed to the retrieval of whole documents. In particular, the Internet encourages information seeking at a macro-level while the major universal systems were designed to organize information at a macro level. Moreover, there is a growing body of research and practical application aimed at improving the situation. This papers examines three of the best known universal classification systems the Dewey Decimal (DDC), Universal Decimal (UDC) and Library of Congress (LCC) classification systems in the light of their ability to respond to the changing nature of information itself. Recent research is briefly examined for its applicability to them. Environmental science, a recently emerging domain, is used as a basis for the analysis.
