Hi, a few clarifications from my side
A more up-to-date link for the data is
here:
https://gist.github.com/jimkont/01f6add8527939c39192bcb3f840eca0
<https://gist.github.com/jimkont/01f6add8527939c39192bcb3f840eca0>
and this dump was not generated with federated queries, as this was
not possible at the time of creation but with a simple script
it is meant only as a proof-of-concept project that showcases
differences in birthdates between Wikidata, Dutch Wikipedia and Greek
Wikipedia as extracted in the DBpedia 2016-04 release, (which also
means that it is based on ~1y old data)
Best,

Dimitris,
Here are links to SPARQL-FED queries that hit both DBpedia and Wikidata
endpoints. Basically, you have a federated query over 3 SPARQL Endpoints.

-- Post about both projects using variant of SPARQL-FED example above.

Hoi,
With the recent introduction of federation for DBpedia, it is
possible to have queries for the DBpedias for a specific language
and Wikidata. I have blogged how we can make use for this [1].
It makes it much easier to compare Wikidata and DBpedia and when
we take this serious and apply some effort we can make a tool like
the one by Pasleim [2] for Wikipedias that do not have a category
for people who died in a given year.
Thanks,
GerardM

Hoi,
I was asked by one of the DBpedia people to write a project
plan.. I gave it a try [1].
The idea is to first compare DBpedia with Wikidata where a
comparison is possible. When it is not (differences in their
classes for instance) it is at first not what we focus on.
Please comment on the talk page and when there are things
missing in the plan, please help it improve.
Thanks,
GerardM

Hi
I don't have an idea about how to develop this, but it
seems like an interesting project!

Hoi,
Much of the content of DBpedia and Wikidata have the
same origin; harvesting data from a Wikipedia. There
is a lot of discussion going on about quality and one
point that I make is that comparing "Sources" and
concentrating on the differences particularly where
statements differ is where it is easiest to make a
quality difference.
So given that DBpedia harvests both Wikipedia and
Wikidata, can it provide us with a view where a
Wikipedia statement and a Wikidata statement differ.
To make it useful, it is important to subset this
data. I will not start with 500.000 differences but I
will begin when they are about a subset that I care
about.
When I care about entries for alumni of a university,
I will consider curating the information in question.
Particularly when I know the language of the Wikipedia.
When we can do this, another thing that will promote
the use of a tool like this is when regularly (say
once a month) numbers are stored and trends are published.
How difficult is it to come up with something like
this. I know this tool would be based on DBpedia but
there are several reasons why this is good. First it
gives added relevance to DBpedia (without detracting
from Wikidata) and secondly as DBpedia updates on RSS
changes for several Wikipedias, the effect of these
changes is quickly noticed when a new set of data is
requested.
Please let us know what the issues are and what it
takes to move forward with this, Does this make sense?
Thanks,
GerardM
