Abstract

Klassische bibliothekarische Indexierungswerkzeuge werden bis heute nur selten fürs Retrieval nutzbar gemacht; die Wichtigkeit, verschiedene dieser Vokabularien zu harmonisieren und integriert zu verwenden, ist noch immer keine Selbstverständlichkeit. Im Rahmen des DFG-Projektes "CrissCross" wird, ausgehend von der deutschen Ausgabe der Dewey-Dezimalklassifikation, eine Verknüpfung zwischen der DDC und der Schlagwortnormdatei (SWD) aufgebaut, um eine verbale Suche über klassifikatorisch erschlossene Bestände zu ermöglichen. Als Verbreiterung der Basis des verbalen Zugriffs wird außerdem das Mapping der amerikanischen LCSH und des französischen RAMEAU angestrebt. Nach einer kurzen Vorstellung von CrissCross und der Abgrenzung gegenüber ähnlichen Unterfangen werden Rückwirkungen semantischer Integration auf die verknüpften Vokabulare diskutiert. Wie müssen und können sich z.B. Thesauri verändern, wenn sie mit anderen (strukturheterologen) Systemen verknüpft sind? Dabei liegt ein Schwerpunkt der Analyse auf dem semantischen Verhältnis üblicher Mappingrelationen zu den verknüpften Begriffen (besonders im Hinblick auf Polysemie). Außerdem wird der Mehrwert fürs Retrieval auf der Basis solcher Wissensorganisationssysteme, z.B. durch automatisierten Zugriff über Ontologien, diskutiert.

Some examples of identifiers for concepts follow: <http://dewey.info/concept/338.4/en/edn/22/> This identifier is used to retrieve or identify the 338.4 concept in the English-language version of Edition 22. <http://dewey.info/concept/338.4/de/edn/22/> This identifier is used to retrieve or identify the 338.4 concept in the German-language version of Edition 22. <http://dewey.info/concept/333.7-333.9/> This identifier is used to retrieve or identify the 333.7-333.9 concept across all editions and language versions. <http://dewey.info/concept/333.7-333.9/about.skos> This identifier is used to retrieve a SKOS representation of the 333.7-333.9 concept (using the "resource" element). There are several open issues at this preliminary stage of development: Use cases: URIs need to represent the range of statements or questions that could be submitted to a Dewey web service. Therefore, it seems that some general questions have to be answered first: What information does an agent have when coming to a Dewey web service? What kind of questions will such an agent ask? Placement of the {locale} component: It is still an open question if the {locale} component should be placed after the {version} component instead (<http://dewey.info/concept/338.4/edn/22/en>) to emphasize that the most important instantiation of a Dewey class is its edition, not its language version. From a services point of view, however, it could make more sense to keep the current arrangement, because users are more likely to come to the service with a present understanding of the language version they are seeking without knowing the specifics of a certain edition in which they are trying to find topics. Identification of other Dewey entities: The goal is to create a locator that does not answer all, but a lot of questions that could be asked about the DDC. Which entities are missing but should be surfaced for services or user agents? How will those services or agents interact with them? Should some entities be rendered in a different way as presented? For example, (how) should the DDC Summaries be retrievable? Would it be necessary to make the DDC Manual accessible through this identifier structure?"
