It would be enough for me to have owl:sameAs links across entities in the

redirect links - even interlanguage one - are present but do use the
rdfs:seeAlso property.

Well there are redirect datasets such as http://downloads.dbpedia.org/3.8/en/redirects_en.nt.bz2 (this one uses dbpedia-owl:wikiPageRedirects)

but that property doesn't really encode the semantics of owl:sameAs which are much stronger.

e.g. you also get stuff like:

    dbpedia:Silvio_Berlusconi    dbpedia-owl:wikiPageRedirects
        dbpedia:Nemi_Letizia , dbpedia:Patrizia_D'Addario .

(who are two young women Berlusconi is said to have had an affair with - not suitable for owl:sameAs).

    dbpedia:Silvio_Berlusconi    dbpedia-owl:wikiPageRedirects
        dbpedia:Psiconano, dbpedia:Il_Cavaliere .

(two of his nicknames, and I would accept that for owl:sameAs)

But come to think of it, perhaps DBPedia is not managing these subtleties yet?

I was thinking you refer to owl:sameAs links to geonames, freebase, ...

That's coming next, but first I need to resolve ambiguities in DBPedia. I'm writing an autocomplete functionality similar to the VIE one, but it should present a single entity only once (and in a very precise way). If I get 10 DBPedia entities and nothing telling me they are (strongly) the same, there's not much of a point in going to other datasets.

Thanks,
Alessandro


I'm not sure if there is a specific dump of what I'm looking for at

http://downloads.dbpedia.org/3.8/en/

iri_same_as_uri_en is only part of what I'm seeking.

I have never understood for what this is useful.

But anyway, if I were to find it and wanted to load it on my own Stanbol,
the reference documentation to follow is still the one on
'entityhub/indexing/dbpedia/README.md' right?

Cheers

Hi Alessandro,

The dbpedia index used on dev.iks-project.eu does not contain
owl:sameAs information. For those to be present one would need to
import the according RDF dump files (by copying them to the
'indexing/resources/rdfdata' directory.

If you make an proposal what links would be interesting we could add
those files to the default configuration of the dbpedia indexing tool

Hi,

I was fiddling around with the demo installation at
http://demo.iks-project.eu/stanbolfull querying the entityhub for an
application I'm working on. Before diving deep into investigation I just
wanted to ask: is that installation indexing owl:sameAs coreferences at
all?

I've been POSTing on
http://demo.iks-project.eu/stanbolfull/entityhub/sites/find with the
following:

* name = "gaddafi"
* limit = "20"
* ldpath = "same = owl:sameAs :: xsd:anyURI ;" (urlencoded)

hoping I didn't botch the trivial LDPath program. Not having much luck
here,
I get several equivalent individuals but no values for "same" e.g.

http://dbpedia.org/resource/Colonel_Gaddafi
http://dbpedia.org/resource/Gaddafi
http://dbpedia.org/resource/Muammar_al-Gaddafi
http://dbpedia.org/resource/Muammar_Gaddafi

I am speculating the DBPedia index over there does not include owl:sameAs
links? Have we an index that does?

Of course I could ask sameas.org but I'm more keen on a Stanbol-only
solution

Best,
Alessandro
