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,
