[Wikidata-l] DBpedia <-> Wikidata mapping questions

Hi Marco,

Thanks for getting in touch. Looking at the list there seems to be many wrong mappings.

Is there any way that we can collaborate to increase the number of matches or does it have to do with qualifiers? And do you plan to document 1:1 matches on your OntologyProperty namespace?

Thanks and regards, Micru

Hi everyone,

The following spreadsheet contains the latest DBpedia <-> Wikidata mapping effort both for properties and classes (cf. the 2 sheets) made by the GSoC student so far.

Since I am his main mentor, feel free to ask me further details. Hope this helps!

Cheers,

Marco

I think it would be cool to use http://mappings.dbpedia.org/ - it
already has
mappings for hundreds of templates in different language versions to
the dbpedia
vocabulary. If we added a mapping for wikidata <-> dbpedia, it
should be easy
enough to derive a mapping between a wikipedia template and
wikidata. Actually,
I was under the impression the wikidata <-> dbpedia already existed,
but I don't
see it on the site right now. Adding Anja Jentzsch, she might know.

Even if it proves too tricky to map individual template parameters
this way, it
should still be possible to at least detect the class (instanceof)
of an item
based on the templates the respective wikipedia page contains. We

should definitely map dpedia classes to wikidata items.

Sergey Skovorodkin is working on a dbpedia<->wikidata mapping as a GsoC for DBpedia this year https://github.com/dbpedia/extraction-framework/wiki/ GSoC-2014-Progress-Sergey-Skovorodkin

I'm CCing him to see if he can report the status or if he might need help with our properties, maybe we are missing some or need to clarify some others. Sometimes we are using qualifiers to extend properties instead of creating new ones.

Cheers, Micru
