Are some triple in freebase is wrong?

[LucienCheng]

in file "FreebaseQA_fb_extract.txt", there some wrong triple , just like ,"m.03_bjc type.object.type government.governmental_jurisdiction". This cause the freebase enviroment can not be imported into virtuoso. Could you please upload the db of the virtuoso or through other ways . Thanks.

If I recall, we used the Freebase dumps provided by Google (https://developers.google.com/freebase) to create FreebaseQA, so there shouldn't be any incorrect triples? In fact, I just checked the example you provided and I was able to find it.

@kelvin-jiang Could you provide a mapping from mid to its name? m.03_bjc seems to an invalid id. Many ids in FreebaseQA_fb_extract.txt are not found in Freebase/Wikidata Mappings or Freebase Easy.

Hi @hankcs, I took a look into m.03_bjc. It is not that it is an invalid ID, but instead it does not appear in the sources you linked for some reason. Using the full Freebase dataset, m.03_bjc is the Freebase MID for Akrotiri and Dhekelia, which in Wikidata is Q37362.

For why it isn't in the Freebase/Wikidata Mapping set, maybe it is because this MID doesn't satisfy this condition?

The data has been created based on the Wikidata-Dump of October 28, 2013, and contains only those links that have at least two common Wikipedia-Links and not a single disagreeing Wikipedia-Link. Furthermore, the lines are sorted by the number of common Wikipedia-Links (although in Turtle this does not really matter).
