Re: [Wikidata-l] Wikidata-Freebase mappings

2015-04-09 Thread Antoine Isaac 

Hi everyone

All this sounds really good and useful!
I was wondering: is there a relation between the Samsung mappings, and the 
Freebase/Wikidata script that Thomas Steiner has recently shared?
https://github.com/google/primarysources/tree/master/frontend

Cheers,

Antoine

Google is already providing the mapping relation between Freebase and 
Wikidata (https://developers.google.com/freebase/data), however, they might not 
offer a updated version. We extract a set of identical relations from both 
Freebase and Wikidata datasets using Wikipedia links; several algorithms are 
also tested to find out same entity pairs. Although this approach is limited to 
identifying all same entities of both datasets, it would be a useful source to 
understand instances of both data sources. The source code for extracting this 
data will also be shared soon.

The data is serialised using the N-Triples format, and the following is the 
details of this data:

- Total 4,395,258 triples (same entity pairs)

- Updated: February 13, 2015

- Data Format: N-Triples RDF

- License: CC0

- File size: 236 MB zip

- File size: 2.5 GB (uncompressed)

Feel free to ask me if you have any questions.

Think of it this way, it is clear freebase / Google already has such
mappings and probably using them as they are the ones that provided them to
us.

I don't see that us also adding the data for the mappings on our side is
going to mean anything... they already know what on freebase links to what
on Wikidata...

Hi Denny,

I asked again about this property because there were some concerns when it
was created. From the comments I infer that the general ethos is "not

I share the feeling, I don't mind linking, but I see little utility for
Wikidata given the different licenses.

Another important thing to note in this context is that all funding for 
Wikidata so far had the form of donations, which is crucially different 
from sponsoring (where you get something in return). The donors who give 
their money hope, of course, that the project will do something that 
they will find useful, but they exercise no control whatsoever in the 
development process. The donations are not bound to any condition, not 
even reporting, and there is no way to retract them. So each donor's 
initial intentions, whatever they were, have no influence on the 
execution of the project (moreover, I Kant think of any reason why the 
intentions rather than the outcome should determine the value of the 
deed ;-).


Cheers,

Markus

Hi Group

Denny, thanks for making that clear. I did not mean to show any mistrust, and 
I'm sorry that I did because I really respect your work.

I regretted writing what I did after thinking about it over lunch, since it is 
not "Assume good faith" towards Google. Maybe one of the reasons that I was 
sensitive to it was because I'm representing VIAF in Wikidata, which is kind of 
the same as Freebase in Wikidata, and I wouldn't want people assuming bad faith 
about VIAF.

Thanks for being clear and open about your work, its a real inspiration.

Hi Max,

indeed, I am not suggesting creating a new property. The data release that was

Regarding the off-topic part of your mail, I want to point out to my personal

Hoi,
If I understand you well,  what you propose is adding links that are similar to 
what we already do to VIAF and so many others. Using data from Freebase is a 
tantalising option. Is there agreement and a license that allows for this?
Thanks,

Hello all,

as you know, I have recently started a new job. My mission to get more free 
data out to the world has not changed due to that, though.

Thus, I am happy to point you today to a step in this direction. We have 
created a mapping of Wikidata Qids to Freebase Mids, and are publishing it 
under CC0, so that anyone can use it in any way they want. The file contains 
about 2 Million mappings.

The download and all further data is available here:
  <https://developers.google.com/freebase/data#freebase-wikidata-mappings>

In particular, I hope that the data will be uploaded to Wikidata. We also plan 
to upload the data to Freebase. The two-way links will ensure that systems 
using either knowledge base can easily merge data, go from one to the other, 
enrich data with each other, etc. We opted to first publish the mappings 
standalone, to make clear that they are under CC0.

The mapping is created based on the Wikidata dumps from end of October. 
Wikidata Items are matched with Freebase Topics based on their respective links 
to Wikipedia. Each mapping says that there have been no disagreeing 
Wikipedia-Links and at least two agreeing Wikipedia-Links, so the data should 
be very clean. Furthermore, the mappings are sorted by the number of agreeing 
Wikipedia-Links, so it is kinda sorted by relevance.

The data is in RDF format. To get the Mids as they are used in Wikidata, the 
replace the namespace
  http://rdf.freebase.com/ns/m.
with
  /m/
The Wikidata Qids are using the Wikidata namespace, i.e. the Qids themselves 
are concatenated to
  http://www.wikidata.org/entity/

If anyone wants to take up the task to upload the data to Wikidata, I can offer 
to help and answer questions and to h

I just went back into the email Archives and a discussion started on
6/14/2013 by Google Developer Relations person Shawn Simister[1] first
proposed this property. There is large thread there about licensing,
ending with Micru having an unanswered question to Shawn about how
Freebase can manage its license since it mixes CC-0 and CC-BY?


License nitpicking is good of course,



Off-topic: this thread is from before Denny announced that he was going
to Google, I believe, is that correct? Whatever happens with licensing,
and regarding Wikidata's CC0, I hope that it wasn't engineered so that
Google could profit from Wikidata. I concede that this thought is mostly
from paranoia, and disagreeing with a lot of Google's politics and
tactics in the past.


but I disagree that we should speculate about people's intention when 
they contribute valid information, especially to a data project like 
Wikidata which mostly contains "facts" (!= truth, sure) and obviously 
needs to be maintained by something more than just the usual suspect 
(the same overworked Wikipedians).

Hello All,

We already do have a freebase ID, similar to the VIAF one- it's 
P646<http://www.wikidata.org/wiki/Property:P646>.
