Oh, I understand. Thanks again.
Is it possible to resolve these names with the dump? I.e. without having
to make network requests?
If not, any tips on how I should proceed to obtain the resolved//name?

So in wikidata dump you will find mappings between sitelinks and QIDs.
A sitelink it is a wikipedia link . for example:
http://en.wikipedia.org/wiki/Obama.
That particular example redirects to another sitelink:
http://en.wikipedia.org/wiki/Barack_Obama (this is the canonical for
this topics/entity)
The mapping from wikipedia sitelinks to QIDs you get on wikidata does
not assure canonical sitelink.
So you can have a mapping telling you that Q123 is linked to "Obama".
However Spotlight would in principle never return "Obama" but its
canonical identifier "Barack_Obama"

Thanks for the swift reply!
What do you mean by resolving redirects? Atm I'm using whatever's
after the slash as dbpedia ID. Is this incorrect? I.e.
http://dbpedia.org/resource/Bridgeport,_Connecticut -->
Bridgeport,_Connecticut

Hi Patrick,
Best approach is to use Wikidata's dumps.
- Wikidata to dbpediaIDs: You can use rdf exports( like [1]).
This include a mapping from wikipedia titles in different
languages to QIDs. Be aware that you might want to resolve
redirects since dbpedia spotlight in principle only returns
canonical dbpediaIDs.
- Freebase: Probably wikidata sitelinks dump (or other dump
file) contains the mapping QID - MID. But also check dbpedia
downloads page, they already provide a dbpeida - mid mapping

Hello.
I'm using DBpedia spotlight to annotate text (using the REST
framework
and a local instance of dbpedia spotlight), but the framework
only gives
me dbpedia ID's. What I really want is Wikidata ID's. I've been
experimenting with Sparql queries and I'm able to fetch
Wikidata ID's
one at the time, however this is too slow when I need millions.
I potentially also want to achieve the same for Freebase ID's.
What is the best way to proceed?
