Wikidata as a Linking Hub for Knowledge Organization Systems? Integrating an Authority Mapping into Wikidata and Learning Lessons for KOS Mappings.
Joachim Neubert · ZBW Publication Archive (ZBW – Leibniz Information Centre for Economics) · 2017
Wikidata has been created in order to support all of the roughly 300 Wikipedia projects. Besides interlinking all Wikipedia pages about a specific item – e.g., a person - in different languages, it also connects to more than 1500 different sources of authority information. We will present lessons learned from using Wikidata as a linking hub for two personal name authorities in economics (GND and RePEc author identifiers) and demonstrate the benefits of moving a mapping from a closed environment to Wikidata as a public and community-curated linking hub. We will further ask to what extent these experiences can be transferred to knowledge organization systems and how the limitation to simple 1:1 relationships (as for authorities) can be overcome. Using STW Thesaurus for Economics as an example, we will investigate how we can make use of existing cross-concordances to “seed” Wikidata with external identifiers, and how transitive mappings to yet un-mapped vocabularies can be earned.
