Hi all,
I was wondering what's the best way to get a mapping between Wikidata QIDs and Google Knowledge Graph (ex-Freebase) MIDs.
We tried to extract the mapping from Wikidata, using the property https://www.wikidata.org/wiki/Property:P646, among others, but it doesn't seem complete, with mappings for only 1.3 million entities -- much less than the number of Wikidata entities.
It is expected that the numbers are not matched because not every topic that now has an Item in Wikidata ever had a freebase entry and vice versa. That being said it is quite possible that it's not complete.
Is there maybe a dedicated dataset or API for this mapping?
https://developers.google.com/freebase#freebase-wikidata-mappings might be helpful for you.
Alternatively, does anyone know of a way of querying the Google KG API [1] directly with the name of a Wikipedia article (or with a Wikidata QID), rather than an arbitrary plain-text string?
Thanks! Bob
