Re: Linked data sets for evaluating interlinking?

Thanks to all who have mentioned other datasets - more fodder for sameAs.org! :-)

Christina,
A separate message from me about datasets.
As the maintainer of sameAs.org, I have quite a lot of such datasets in quite convenient forms (only the links) :-)
So, for example, if you wanted Adrian's data, then I can give it to you.
(I have queried the SPARQL endpoint to put stuff in sameAs.org. Both owl:sameAs and skos:exactMatch.)
I have lots of bibliographic ones, especially national libraries, who have often sent me the data.
(British, German, US, Japanese, Norwegian, French, Spanish, Hungarian … as best I recall.)
I also have the VIAF data.
This is all aggregated in http://sameas.org/store/kelle/ and other stuff is kept in some sameAs stores - see http://sameas.org/store/
Freebase is an interesting one (that is Google Graph, and they send me their data.)
LATC has been mentioned, and I have a store with that data.

Also, Rob Warren is spot on!
owl:differentFrom is your friend.
It can be used to tell you the resources that might have been considered the same, but some more work has been done to find out that the system was wrong.
In some sense it gives you upper and lower bounds on precision/recall.

It so happens (!) that I also run http://differentfrom.org where I gather such data.
Again, Freebase have given me their regression test for asserting sameness, and I have a store with that in.
And LATC published their similar data, and I have put it in a store.

I hope that helps - ask me for data if you need it, although I hope you can be as specific as possible.
(If I don't have it, I may well decide to harvest it to put in sameas.org.)

Best
Hugh

We've been doing a lot of work just recently in fact, and we've published a blog post that's picked up quite a bit of interest on this - http://archiveshub.ac.uk/blog/2013/08/hub-viaf-namematching/. We haven't published our latest run of data yet, but we hope to finish this soon. It'll probably still be about a month or so as a few of us are on holiday soon.

I would need pairs of data sets which have been manually linked, or data sets which have been (semi-)automatically linked with interlinking tools, and afterwards reviewed (to include the links which are not identified by tools). I have looked into the DataHub catalogue and queried VoiD descriptions, but unfortunately the information about how the interlinking process was carried out is often missing.
