KG Linkage Problem #130

Closed erictopi closed 4 months ago

erictopi commented 5 months ago

Am I missing something or is the link file between the movie IDs and the freebase IDs for the MovieLens dataset incorrect? For example: Titanic has the ID 313 and is linked to the freebase ID m.0b8l01 in the link file. If I look up this freebase ID on wikidata I get the movie The Swan Princess. For me, the wrong linkage wouldn't be a problem if it was consistant with the knowledge graph. But when I check m.0b8l01 in the kg file, I get the ID m.0ccv3s, which is the director Richard Rich who is indeed the director of The Swan Princess and has nothing to do with the movie Titanic.

Would be great if someone could check if I'm right or explain to me what I'm getting wrong

Cheers
