    Abstract
    Die Dewey-Dezimalklassifikation (DDC) ist ein mächtiges Instrument der klassifikatorischen Inhaltserschließung. Immer mehr Bibliotheken im In- und Ausland erkennen den Nutzen der international am weitesten verbreiteten Universalklassifikation. Die Deutsche Nationalbibliothek (DNB) setzt die DDC seit 2006 für die inhaltliche Erschließung der Bibliografiereihen A, B und H ein. Seitdem wurden rund 800.000 Publikationen mit DDC-Notationen versehen. Der Nutzen von Klassifikationen ist unter Bibliothekar/innen unumstritten. Die Bibliotheksnutzer/innen hingegen wissen oft nicht, dass der Katalog ihrer Bibliothek auch eine systematische Recherche ermöglicht. Ihre Recherchestrategie ist meist verbal. Durch Internetsuchmaschinen wird diese Strategie noch bestärkt. Daher liegt es nahe, auch für die klassifikatorisch erschlossenen Titel einen verbalen Sucheinstieg zu schaffen. ie DDC enthält nicht nur die in vielen Klassifikationssystemen üblichen Registereinträge und Klassenbenennungen, sondern auch die im Rahmen des Projekts CrissCross in großem Umfang erstellten Verknüpfungen zu Schlagwörtern der Gemeinsamen Normdatei (GND), die für diesen Zweck ausgewertet werden können.

    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
    Exploring collections by their subject matter is an important functionality for library users. We developed an online tool called SciGator in order to allow users to browse the Dewey Decimal Classification (DDC) classes used in different libraries at the University of Pavia and to perform different types of search in the OPAC. Besides navigation of DDC hierarchies, SciGator suggests "see-also" relationships with related classes and maps equivalent classes in local shelving schemes, thus allowing the expansion of search queries to include subjects contiguous to the initial one. We are developing new features, including the possibility to expand searches even more to national and international catalogues.

    Abstract
    Pflege und Anwendung von Klassifikationssystemen für Informationsressourcen sind traditionell eine Kernkompetenz von Bibliotheken. Diese Systeme sind häufig historisch gewachsen und die Veröffentlichung verschiedener Systeme ist in der Vergangenheit typischerweise durch gedruckte Regelwerke oder proprietäre Datenbanken erfolgt. Die Technologien des semantischen Web erlauben es, Klassifikationssysteme in einer standardisierten und maschinenlesbaren Weise zu repräsentieren, sowie als Linked (Open) Data für die Nachnutzung zugänglich zu machen. Anhand ausgewählter Beispiele von Klassifikationssystemen, die bereits als Linked (Open) Data publiziert wurden, werden in diesem Artikel zentrale semantische und technische Fragen erörtert, sowie mögliche Einsatzgebiete und Chancen dargestellt. So kann beispielsweise die für die Maschinenlesbarkeit erforderliche starke Strukturierung von Daten im semantischen Web zum besseren Verständnis der Klassifikationssysteme beitragen und möglicherweise positive Impulse für ihre Weiterentwicklung liefern. Für das semantische Web aufbereitete Repräsentationen von Klassifikationssystemen können unter anderem zur Kataloganreicherung oder für die anwendungsbezogene Erstellung von Konkordanzen zwischen verschiedenen Klassifikations- bzw. Begriffssystemen genutzt werden..

    Abstract
    Die Dewey-Dezimalklassifikation (DDC) wird weltweit für die Erschließung von Bibliotheksbeständen eingesetzt. Um immer auf dem aktuellen wissenschaftlichen Stand zu sein, wird die DDC regelmäßig aktualisiert. Hierdurch kann es zu Begriffsverschiebungen kommen und die Erschließung ähnlicher Titel weicht voneinander ab, wird also heterogen, was zu inkorrekten Treffermengen bei der Suche nach DDC-erschlossenen Dokumenten führen kann. Eine mögliche Lösung des Problems ist, jeder Version einer DDC-Klasse einen eindeutigen Identifier zuzuordnen und so die Klasse eindeutig identifizieren zu können, mit der ein Titel verknüpft ist. Mit Hilfe von RDF kann aus Titeldaten, Schlagwörtern der Schlagwortnormdatei und den versionierten DDC-Klassen ein semantisches Netzwerk modelliert werden und durch entsprechende Anfragen können genauere Suchergebnisse, unabhängig von Änderungen in der DDC, generiert werden. Die Untersuchungen erfolgten im Rahmen eines Werkvertrages mit der Deutschen Nationalbibliothek und wurden in ausgearbeiteter Form als Masterthesis eingereicht.

    Abstract
    Die in ihren Grundzügen hierarchisch angelegte Aufstellungssystematik der Bibliothek der Universität Konstanz ist im Laufe der Zeit durch zahlreiche nicht-hierarchische Strukturen ergänzt worden, so dass ein heterogenes Gebilde entstanden ist. Außerdem kam der Wunsch nach Austauschbarkeit der Konstanzer Klassifikation mit anderen bibliothekarischen Einrichtungen auf. Aus diesen Gründen soll die Systematik nun bereinigt werden. Dazu wird als zentrales Werkzeug ein Diagnosealgorithmus benötigt, welcher sichtbar macht, wie weit die aktuelle Systematik von einem vorher zu definierenden, möglichst baumförmigen Idealzustand entfernt ist. In diesem Projekt ist ein solcher Algorithmus entwickelt und implementiert worden.

    Abstract
    The vision of the semantic web is gradually unfolding and taking shape through a web of linked data, a part of which is built by capturing semantics stored in existing knowledge organization systems (KOS), subject metadata and resource metadata. The content of vast bibliographic collections is currently categorized by some widely used bibliographic classification and we may soon see them being mined for information and linked in a meaningful way across the web. Bibliographic classifications are designed for knowledge mediation, which offers both a rich terminology and different ways in which concepts can be categorized and related to each other in the universe of knowledge. From 1990 to 2010 they have been used in various resource discovery services on the web, and they continue to be used to support information integration in a number of international digital library projects. In this chapter we will revisit some of the ways in which universal classifications, as language-independent concept schemes, can assist humans and computers in structuring and presenting information and formulating queries. Most importantly, we will highlight issues important to understanding bibliographic classifications, identifying both their unused potential and their technical limitations.
