Hi all,
I am pleased to announce that the Freebase-Wikidata mappings are shared in public.
http://github.com/Samsung/KnowledgeSharingPlatform
Google is already providing the mapping relation between Freebase and Wikidata (https://developers.google.com/freebase/data), however, they might not offer a updated version. We extract a set of identical relations from both Freebase and Wikidata datasets using Wikipedia links; several algorithms are also tested to find out same entity pairs. Although this approach is limited to identifying all same entities of both datasets, it would be a useful source to understand instances of both data sources. The source code for extracting this data will also be shared soon.
The data is serialised using the N-Triples format, and the following is the details of this data:
- Total 4,395,258 triples (same entity pairs)
- Updated: February 13, 2015
- Data Format: N-Triples RDF
- License: CC0
- File size: 236 MB zip
- File size: 2.5 GB (uncompressed)
Feel free to ask me if you have any questions.
Cheers,
