Re: [Dbpedia-discussion] Fwd: [extraction-framework] Update the CreateFreebaseLinks based on the new Freebase RDF dump format (#25)

Hi Andrea, Wikipedia page ids (URL parameter curid) are more stable than page titles, and according to Tom, Freebase uses them as the main links to Wikipedia, but DBpedia still uses the current page title as the canonical resource IRI, so the DBpedia-to-Freebase linkset has to use the page title.

Sorry, wrong information. We should use Page Ids ( http://downloads.dbpedia.org/3.8/en/page_ids_en.nt.bz2) I am going to try something. Cheers Andrea 2013/3/25 Andrea Di Menna > Hi, > > we have article numeric ids in the quads file (as oldid parameter). > Jona, do you think this is worth givi

Hi, we have article numeric ids in the quads file (as oldid parameter). Jona, do you think this is worth giving a try? Regards Andrea 2013/3/25 Tom Morris > Another approach might be to use the recently introduced Topic Equivalent > Webpage property: > > ns:m.09q3rp ns:common.topic.topic_e

Re: [Dbpedia-discussion] Fwd: [extraction-framework] Update the CreateFreebaseLinks based on the new Freebase RDF dump format (#25)

Another approach might be to use the recently introduced Topic Equivalent Webpage property: ns:m.09q3rp ns:common.topic.topic_equivalent_webpage< http://pt.wikipedia.org/wiki/Marlín>. ns:m.09q3rp ns:common.topic.topic_equivalent_webpage< http://es.wikipedia.org/wiki/Marlín_

I wouldn't claim that Freebase is bug-free, but that's a quite old and simple algorithm, so unless they're triples from very early in it's life (say, 2007), I'd guess that bad input data from Wikipedia is more likely than a problem with the transformation. It might help to give a little background

Re: [Dbpedia-discussion] Fwd: [extraction-framework] Update the CreateFreebaseLinks based on the new Freebase RDF dump format (#25)

Hi all, it looks like there are actually some pages in Wikipedia which contain wrong data, which is where the pages originate from in Freebase, e.g. http://en.wikipedia.org/wiki/Marl%C3%83%C2%ADn,_%C3%83%C2%81vila This page has been deleted on Jan 21, and this actually lead to the Freebase key

Hi, Maybe the only thing that can be done is to notify the freebase discussion list about this problem. Agree with Jona that the number of problematic references is not relevant. Cheers Andrea 2013/3/25 Jona Christopher Sahnwaldt > > On Mar 25, 2013 3:32 AM, "Tom Morris" wrote: > > > > Can so

Can someone point to the part of the discussion which talks about what the problem is? This thread seems to start in mid-stream... Freebase's MQL key encoding (http://wiki.freebase.com/wiki/MQL_key_escaping) is a completely private encoding which shouldn't have any effect on external URIs/IRIs/re
