All, There is a syntax problem with the Freebase dump. I don't know if the dump was prepared by the DBpedia team or by someone at MetaWeb, can anyone tell me who made it?
Anyway, here is the problem: The Freebase dump at http://downloads.dbpedia.org/3.2/links/freebaselinks.zip begins like this: @prefix owl: <http://www.w3.org/2002/07/owl#> . @prefix fb: <http://rdf.freebase.com/ns/> . @prefix dbpedia: <http://dbpedia.org/resource/> . dbpedia:%21%21%21 owl:sameAs fb:guid.9202a8c04000641f80000000002d1e19 . dbpedia:%21%21%21Fuck_You%21%21%21 owl:sameAs fb:guid.9202a8c04000641f8000000000bb290d . That's invalid Turtle, QNames are not allowed to include %-encoded characters. This means Sindice staff has to manually exclude this dump when indexing DBpedia. The fix would be simply to use full URIs: <http://dbpedia.org/resource/%21%21%21> instead of dbpedia:%21%21%21 . I logged a bug here: https://sourceforge.net/tracker2/?func=detail&aid=2657618&group_id=190976&atid=935520 Kudos to Nickolai for finding and verifying this bug.
