Ontology-based metadata

Abstract

We propose a new catalog based on a formal ontological model of bibliographic relations. A hierarchy of five central concepts describes the creation of work. Each kind of relation between works occurs at a particular level in the hierarchy. Related works share data at some level of the hierarchy, yielding a tree structure that reduces redundant representation of shared attributes.To show that ontology-based metadata is practical, we generated a knowledge base of metadata from a sample of MARC records. We implemented the ontology in description logic (Loom), mapped Machine Readable Cataloging (MARC) attributes and values to the ontology, and loaded the data into Loom with all values treated its separate instances. We then unified matching instances, and deduced relations between works. This process thus converts relationships implicit in MARC into explicit relations that arc easy to utilize with computers.Our web interface permits browsing by navigating relations between works. Ontology-based metadata can also support user inquiry and digital-library operation in other important ways.

Modeling Our Understanding, Understanding Our Models – The Case of Inheritance in FRBR

“…FRBR has been analyzed critically by a number of authors (Weinstein, 1998;Abrams, 2002;Taniguchi, 2002, Carlyle 2004. Some have proposed alternatives with more or fewer entities, or different assignments of attributes to entities, or a radically different general framework altogether.…”

Memoria organizacional para el soporte de gestión documental en actividades de investigación

“…En los trabajos de Fensel et al (2000), Gandon (2004), Harris et al (2004), Guarino (1998) Weinstein (1997), se concluye que el uso de ontologías para la inserción de metadatos en recursos de conocimiento puede mejorar en gran manera los sistemas de búsqueda y transferencia de conocimiento. De hecho, en el trabajo de Vasconcelos, Gouveia y Kimble (2002) se puede observar como a través del uso de ontologías se soporta un sistema de memoria organizacional para un proyecto de gestión del conocimiento.…”

User‐Centered evaluation of metadata schema for nonmovable cultural heritage: Murals and stone cave temples

“…This has been reflected in the drafted schema evaluated in this study. Terms from thesauri are required or suggested for some elements such as “Object/Work Type” and “Grade.” Ontology‐based metadata has also been widely studied, as it helps with the integration of entities and standardization of terminologies for the cultural heritage domain (Weinstein, ; Maedche & Zacharias, ; Schuurman & Leszczynski, ). With the help of computational technologies, several digital libraries and online repositories of cultural heritage sites have been established worldwide, including the Digital Dunhuang project, HistoricPlacesLA, and Ancient Locations .…”
