Abstract

Die hier aufgeführten Regeln beziehen sich ausschließlich auf hier aufgeführte Relationsarten und die Beziehungen unter ihnen. Die Ergebnisse sind in Zusammenarbeit mit der Thesaurusredaktion des Projekts ATLAS entstanden (ATLAS 1990). Gedanken von Rostek & Fischer (1988), Schäuble (1989), Vanek (1980), Sick (1989) und Konrad (1990) sowie die Empfehlungen der DIN 1463 (1987) wurden mit berücksichtigt. Diese Regeln werden außerdem für die Entwicklung des Textinterpretationssystem ATLAS/ti (Muhr 1990) und ATLAS/PfleSaurus (Willenborg 1991) weiterverwendet. Punkt 1. enthält Definitionen: Thesaurus, Thesaurusrelationen und deren formal logische Eigenschaften. Punkt 2. enthält Konsistenzregeln. Punkt 3. enthält Inferenzregeln. Punkt 4. enthält zwei Beispielthesauri. Ein System zur Erstellung und Pflege von Thesauri solllte die unter Punkt 1.-3. beschriebenen Definitionen und Regeln berücksichtigen.

Abstract

Moderne Verfahren des Information Retrieval verlangen nach aussagekräftigen und detailliert relationierten Dokumentationssprachen. Der selektive Transfer einzelner Modellierungsstrategien aus dem Bereich semantischer Technologien für die Gestaltung und Relationierung bestehender Dokumentationssprachen wird diskutiert. Am Beispiel des Gegenstandsbereichs "Theater" der Schlagwortnormdatei wird ein hierarchisch strukturiertes Relationeninventar definiert, welches sowohl hinreichend allgemeine als auch zahlreiche spezifische Relationstypen enthält, welche eine detaillierte und damit funktionale Relationierung des Vokabulars ermöglichen. Die Relationierung des Gegenstandsbereichs wird als Ontologie im OWL-Format modelliert. Im Gegensatz zu anderen Ansätzen und Überlegungen zur Schaffung von Relationeninventaren entwickelt der vorgestellte Vorschlag das Relationeninventar aus der Begriffsmenge eines vorgegebenen Gegenstandsbereichs heraus. Das entwickelte Inventar wird als eine hierarchisch strukturierte Taxonomie gestaltet, was einen Zugewinn an Übersichtlichkeit und Funktionalität bringt.

Abstract

The SAC Subcommittee on Subject Relationships/Reference Structures was authorized at the 1995 Midwinter Meeting and appointed shortly before Annual Conference. Its creation was one result of a discussion of how (and why) to promote the display and use of broader-term subject heading references, and its charge reads as follows: To investigate: (1) the kinds of relationships that exist between subjects, the display of which are likely to be useful to catalog users; (2) how these relationships are or could be recorded in authorities and classification formats; (3) options for how these relationships should be presented to users of online and print catalogs, indexes, lists, etc. By the summer 1996 Annual Conference, make some recommendations to SAC about how to disseminate the information and/or implement changes. At that time assess the need for additional time to investigate these issues. The Subcommittee's work on each of the imperatives in the charge was summarized in a report issued at the 1996 Annual Conference (Appendix A). Highlights of this work included the development of a taxonomy of 165 subject relationships; a demonstration that, using existing MARC coding, catalog systems could be programmed to generate references they do not currently support; and an examination of reference displays in several CD-ROM database products. Since that time, work has continued on identifying term relationships and display options; on tracking research, discussion, and implementation of subject relationships in information systems; and on compiling a list of further research needs.
