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

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

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.

Abstract

Purpose - This research project aims to provide a new visual representation of the Artefacts Canada digital collection, as well as a means for users to browse this content. Artefacts Canada Humanities is a database containing approximately 3.5 million records describing the different collections of Canadian museums. Design/methodology/approach - A four-step methodology was adopted for the development of the faceted taxonomy model. First, a best practice review consisting of an extensive analysis of existing terminology standards in museum communities and public web interfaces of large cultural organizations was performed. The second step of the methodology entailed a domain analysis; this involved extracting and comparing relevant concepts from terminological authoritative sources. The third step proceeded to term clustering and entity listing,which involved the breaking-up of the taxonomy domains into potential facets. An incremental user testing was also realized in order to validate and refine the taxonomy components (facets, values, and relationships). Findings - The project resulted in a bilingual and expandable vocabulary structure that will further be used to describe the Artefacts Canada database records. The new taxonomy simplifies the representation of complex content by grouping objects into similar facets to classify all records of the Artefacts Canada database. The user-friendly bilingual taxonomy provides worldwide visitors with the means to better access Canadian virtual museum collections. Originality/value - Few methodological tools are available for museums which wish to adopt a faceted approach in the development of their web sites. For practitioners, the methodology developed within this project is a direct contribution to support web site development of large cultural organizations.

Abstract

Dewey Decimal Classification has been used to organize materials owned by the three scientific libraries at the University of Pavia, and to allow integrated browsing in their union catalogue through SciGator, a home built web-based user interface. Classification acts as a bridge between collections located in different places and shelved according to different local schemes. Furthermore, cross-discipline relationships recorded in the system allow for expanded queries that increase recall. Advantages and possible improvements of such a system are discussed.
