Dear all,
Following up on the early prototype we announced earlier [1] we are happy to announce a consolidated Wikidata RDF dump based on DBpedia. (Disclaimer: this work is not related or affiliated with the official Wikidata RDF dumps)
We provide:
- sample data for preview http://wikidata.dbpedia.org/downloads/sample/
- a complete dump with over 1 Billion triples:
http://wikidata.dbpedia.org/downloads/20150330/
- a SPARQL endpoint: http://wikidata.dbpedia.org/sparql
- a Linked Data interface: http://wikidata.dbpedia.org/resource/Q586
Using the wikidata dump from March we were able to retrieve more that 1B triples, 8.5M typed things according to the DBpedia ontology along with 48M transitive types, 6.4M coordinates and 1.5M depictions. A complete report for this effort can be found here: http://svn.aksw.org/papers/2015/ISWC_Wikidata2DBpedia/public.pdf
The extraction code is now fully integrated in the DBpedia Information Extraction Framework.
We are eagerly waiting for your feedback and your help in improving the DBpedia to Wikidata mapping coverage http://mappings.dbpedia.org/server/ontology/wikidata/missing/
Best,
Ali Ismayilov, Dimitris Kontokostas, Sören Auer, Jens Lehmann, Sebastian Hellmann
