Abstract

Authority files have played an important role in improving the quality of indexing and subject cataloging. Although authorities can significantly improve search by increasing the number of access points, they are rarely an integral part of the information retrieval process, particularly end-users searches. A retrieval prototype, searchFAST, was developed to test the feasibility of using an authority file as an index to bibliographic records. searchFAST uses FAST (Faceted Application of Subject Terminology) as an index to OCLC's WorldCat.org bibliographic database. The searchFAST methodology complements, rather than replaces, existing WorldCat.org access. The bibliographic file is searched indirectly; first the authority file is searched to identify appropriate subject headings, then the headings are used to retrieve the matching bibliographic records. The prototype demonstrates the effectiveness and practicality of using an authority file as an index. Searching the authority file leverages authority control work by increasing the number of access points while supporting a simple interface designed for end-users.

Abstract

Die Gemeinsame Normdatei (GND) ist seit April 2012 die Datei, die die im deutschsprachigen Bibliothekswesen verwendeten Normdaten enthält. Folglich muss auf Basis dieser Daten eine Repräsentation für die Darstellung als Linked Data im Semantic Web etabliert werden. Neben der eigentlichen Bereitstellung von GND-Daten im Semantic Web sollen die Daten mit bereits als Linked Data vorhandenen Datenbeständen (DBpedia, VIAF etc.) verknüpft und nach Möglichkeit kompatibel sein, wodurch die GND einem internationalen und spartenübergreifenden Publikum zugänglich gemacht wird. Dieses Dokument dient vor allem zur Beschreibung, wie die GND-Linked-Data-Repräsentation entstand und dem Weg zur Spezifikation einer eignen Ontologie. Hierfür werden nach einer kurzen Einführung in die GND die Grundprinzipien und wichtigsten Standards für die Veröffentlichung von Linked Data im Semantic Web vorgestellt, um darauf aufbauend existierende Vokabulare und Ontologien des Bibliothekswesens betrachten zu können. Anschließend folgt ein Exkurs in das generelle Vorgehen für die Bereitstellung von Linked Data, wobei die so oft zitierte Open World Assumption kritisch hinterfragt und damit verbundene Probleme insbesondere in Hinsicht Interoperabilität und Nachnutzbarkeit aufgedeckt werden. Um Probleme der Interoperabilität zu vermeiden, wird den Empfehlungen der Library Linked Data Incubator Group [LLD11] gefolgt.

Abstract

Every standard embodies a particular set of values. Some aspects are privileged while others are masked. Values embedded within knowledge organization standards have special import in that they are further perpetuated by the data they are used to generate. Within libraries, descriptive catalog codes serve as prominent knowledge organization standards, guiding the creation of resource representations. Though the historical and functional aspects of these standards have received significant attention, less focus has been placed on the values associated with such codes. In this study, a critical, historical analysis of ten Anglo-American descriptive catalog codes and surrounding discourse was conducted as an initial step towards uncovering key values associated with this lineage of standards. Two values in particular were found to be highly significant: authority and universalism. Authority is closely tied to notions of power and control, particularly over practice or belief. Increasing control over resources, identities, and viewpoints are all manifestations of the value of authority within descriptive codes. Universalism has guided the widening coverage of descriptive codes in regards to settings and materials, such as the extension of bibliographic standards to non-book resources. Together, authority and universalism represent conventional values focused on facilitating orderly social exchanges. A comparative lack of emphasis on values concerning human welfare and empowerment may be unsurprising, but raises questions concerning the role of human values in knowledge organization standards. Further attention to the values associated with descriptive codes and other knowledge organization standards is important as libraries and other institutions seek to share their resource representation data more widely
