- 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
- Examines ho well UDC numbers performs as a subject retrieval device in online systems. Discusses: truncation, coordination, USC as a discipline based scheme, ranges, and requirements in search software. Gives examples of UDC in pre-coordinated and post-coordinated working systems. Discusses the possible use of UDC as a thesaurus. Outlines improvements that would enable its use in online retrieval

- "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).
Das Neueste zuerst Die Herausgeber der DDC präsentierten eine neue Informationsplattform "025.431: The Dewey blog"; seit Anfang Juli erreichbar unter http://ddc.typepad.com/. Neu ist auch der fünfsprachige, mit einem Farbleitsystem ausgestattete "DeweyBrowser" von OCLC; der Protoyp führt bereits in einen Katalog von 125.000 e-books und kann unter http://ddcresearch.oclc.org ,i ebooks/fileServer erprobt werden. OCLC bietet seit April 2005 eine neue Current Awareness-Schiene zur DDC mit unterschiedlichen Schwerpunkten an: Dewey Mappings, Dewey News, DeweyTips, Dewey Updates, Deweyjournal (letzteres fängt Themen aus allen 4 Teilbereichen auf); zu subskribieren unter http://www.oclc.org/dewey/syndicated/rss.htm. Wichtig für Freihandaufstellungen Die Segmentierung von Dewey-Notationen wurde reduziert! Ab September 2005 vergibt LoC nur noch ein einziges Segmentierungszeichen, und zwar an der Stelle, an der die jeweilige Notation in der englischen Kurzausgabe endet. Der Beginn einer Teilnotation aus Hilfstafel 1: Standardunterteilungen, wird also nun nicht mehr markiert. Für die Bildung von Standortsignaturen bietet sich das Dewey Cutter Programm an; Downloaden unter www.oclc.org/dewey/support/program.
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
- In a global context characterized by the massive use of information technology and communications any organization needs to optimize the search and document management processes. In this paper an analysis of modern document management techniques and computational strategies with specialized language resources is presented and a model that can be used in automatic text categorization in the context of organizations is proposed.As a particular case we describe a classification system according to the taxonomy JEL (Journal of Economic Literature) and that makes use of multilingual glossaries for hierarchical classifications of scientific and technical documents related to the business functional areas.

- Abstract
- Selection of search terms in an online search environment can be facilitated by the visual display of a knowledge map showing the various concepts and their links. This paper reports an a preliminary research aimed at designing a prototype knowledge map using DDC and its visual display. The prototype knowledge map created using the Protégé and TGViz freeware has been demonstrated, and further areas of research in this field are discussed.

- 1. Introduction Web search engines and digital libraries usually expect the users to use search terms that most accurately represent their information needs. Finding the most appropriate search terms to represent an information need is an age old problem in information retrieval. Keyword or phrase search may produce good search results as long as the search terms or phrase(s) match those used by the authors and have been chosen for indexing by the concerned information retrieval system. Since this does not always happen, a large number of false drops are produced by information retrieval systems. The retrieval results become worse in very large systems that deal with millions of records, such as the Web search engines and digital libraries. Vocabulary control tools are used to improve the performance of text retrieval systems. Thesauri, the most common type of vocabulary control tool used in information retrieval, appeared in the late fifties, designed for use with the emerging post-coordinate indexing systems of that time. They are used to exert terminology control in indexing, and to aid in searching by allowing the searcher to select appropriate search terms. A large volume of literature exists describing the design features, and experiments with the use, of thesauri in various types of information retrieval systems (see for example, Furnas et.al., 1987; Bates, 1986, 1998; Milstead, 1997, and Shiri et al., 2002).

- Abstract
- Der Beitrag berichtet über eine unter der Bibliothekssoftware "Aleph 500" neu eingerichtete Normdatei, die mehrere "koexistierende" lokale Klassifikationssysteme aus den Bibliotheken des Österreichischen Bibliothekenverbundes aufzunehmen vermag. Implementiert wurden darin als erste Klassifikation jene der Universitätsbibliothek Bodenkultur (Wien), für die nach dem Auslaufen einer früheren Softwarelösung eine neue Plattform gesucht worden war. Folgende Aspekte werden im Detail angesprochen bzw. dokumentiert: Struktur und Besonderheiten dieser Klassifikation, Gliederung des Gesamtprojektes in mehrere Phasen und Realisierung der ersten Phase (Tabellen-Setup inkl. Kategorienschema, Überführung der Daten in die neue Normdatei, Indexierung). Die neue Multi-Klassifikations-Normdatei ist bereit für die Aufnahme weiterer lokaler Systematiken, wobei diese einerseits von den an der Verbundzentrale geführten Lokalsystemen, andererseits aber auch von den anderen Lokalsystemen des Verbundes stammen können.

- Abstract
- This is a preprint to be published in the Extensions & Corrections to the UDC. The paper explains the basic functions of browsing and searching that need to be supported in relation to analytico-synthetic classifications such as Universal Decimal Classification (UDC), irrespective of any specific, real-life implementation. UDC is an example of a semi-faceted system that can be used, for instance, for both post-coordinate searching and hierarchical/facet browsing. The advantages of using a classification for IR, however, depend on the strength of the GUI, which should provide a user-friendly interface to classification browsing and searching. The power of this interface is in supporting visualisation that will 'convert' what is potentially a user-unfriendly indexing language based on symbols, to a subject presentation that is easy to understand, search and navigate. A summary of the basic functions of searching and browsing a classification that may be provided on a user-friendly interface is given and examples of classification browsing interfaces are provided.

- Abstract
- This paper discusses constraints in knowledge organisation for information retrieval introduced by the difficulty of separating logical views of data, information, concepts and their relationships, from the physical means by which we seek to implement retrieval systems. A parallel is drawn between the move from enumerated to faceted classification and the emergence of relational database management systems to replace those adopting a hierarchical structure. This parallel suggests a convergence of ideas which have been, to a large extent, developed independently. The role of post-coordinated retrieval systems and thesauri is then examined before an interface design (HIBROWSE - a High resolution Interface for BROWsing and SEarching databases), is described which brings together the principles of faceted classification and increases the bandwidth of interaction through view-based searching.

- 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.
