FYI Lydia
the people at WikiTree
https://www.wikidata.org/wiki/Property_talk:P2949 has connected 200
000 people to Wikidata and every week they run a checks of 22 million profiles and has
done this I guess since 2016
* checks between WikiTree and WIkidata
* WikiTree is an old Wiki version with a lot of customizations...
* uploads the diff to Wikidata
* the dev cc: Aleš is then also doing some 300 checks of the 22 million profiles
* sanity check with > 300
rules<https://www.wikitree.com/index.php?title=Category:DD_Suggestions_H…
* checking other sites like FindAgrave
* create statistics like people connected to
Wikidata<https://wikitree.sdms.si/default.htm?report=stat1&dataID=501&Year=0>
* people has produced
videos<https://www.wikitree.com/wiki/Space:Data_Doctors_Project_Video_Co… of
the different rules
* on every profile in WIkiTree you can check the sanity and see if they have a diff
with e.g. Wikidata and/or if Wikidata suggest a relation that is not in WikiTree
* they fix errors in Wikidata but I am not 100% sure if we in WIkidata corrects
them
* my guess we see some errors on Database reports/Constraint
violations<https://www.wikidata.org/wiki/Wikidata:Database_reports/Const…
* all changes done
Here some links
* example how a new run is
anmounced<https://www.wikitree.com/g2g/1243471/suggestions-news-and-upda…
* the space for the 23 may
run<https://www.wikitree.com/wiki/Space:Data_Doctors_Report_2021-05-23&g…
* the Wikidata section of errors
* [cid:fb8d58a6-5241-456d-8641-5c0ab34b0dd9]
* total errors with WIkidata 79956
* new errors 530
* hidden I guess is on protected profiles
* error 541 is clue for father
*
https://www.wikitree.com/wiki/Space:DBE_541
* where you have structured sections like Possible Causes, Action Steps,
* you have this for about xxx errors
* there is also a WIkiTree+ area that is a little bit hardcore
*
https://wikitree.sdms.si/default.htm?report=err6&Query=&MaxErrors=1…
* and on every WikiTree profile you can see the errors related to that
persons....
The excellent with the Wikitree people of people doing genealogy is that they have a
community feeling and care about the profiles so when we massupload 600 000 maybe not so
good profiles in WIkidata then they get chaos... but after some Wikidata related
discussion<https://www.wikitree.com/g2g/tag/wikidata> why do we link Wikidata they
fix the errors 😉

Subject: [Wikidata] Re: Wikidata Digest, Vol 114, Issue 19
Thanks Luca!
The tool we've been digging into for quite a while now is different
from MixnMatch.
MixnMatch is meant to help you connect an entry in a catalog with its
corresponding Wikidata Item. Once you found the corresponding Item a
new external identifier statement can be added to the Item to store
this connection permanently. Having these connections is a very very
useful base for what we're looking into now.
The tool we are envisioning is meant to find the cases where the
actual data in an Item does not match the data in another database
that also has an entry on it and then help editors to resolve those
mismatches. A concrete example would be a person with a date of birth
on their Item in Wikidata. They also have an entry in the German
National Library. Now we can potentially look at the date of birth in
the person's entry in the German National Library and compare it to
the date of birth Wikidata has. If they don't match someone should
probably have a look at it and see where the problem is and
potentially fix it. This is however not a trivial thing and we're
still figuring out how exactly it will work so things might shift a
bit in the coming weeks.
Cheers
Lydia
