Ein semantisches Netz für die Suche mit der Dewey-Dezimalklassifikation - Optimiertes Retrieval durch die Verwendung versionierter DDC-Klassen

摘要

A semantic network for the search with the Dewy Decimal Classification - optimized retrieval by using versioned DDC classes: The Dewey Decimal Classification (DDC) is used to catalogue library holdings all over the world. In order to keep the classification up-to-date with scientific advancement, the DDC is revised regularly. As a result, particular topics might be relocated and the original DDC notation might not represent the topic of a resource any more. This can lead to incorrect search results. A possible solution for this problem is to assign a unique identifier to each version of a DDC class. By doing that, it is possible to explicitly label which version of a DDC class was used for the classification of a particular resource. Bibliographic resources, terms from the German Subject Headings, and the different versions of the DDC classes can then be used to build a semantic network. Using the semantic network with appropriate queries allows for better search results independent of modifications within the DDC.
