Hi all,
Writing to this list because I swear I've seen it discussed here before...
I'm curious to know how many cases we have where two people share both
a name and a birthdate *but are confirmed to be different people*. I
vaguely remember this being discussed as part of the duplicate
checking work, but can't put my finger on where this was. I've been
able to find markers onwiki for "person with the same name as another
person" and "person with the same birth and death dates", but neither
of these are quite the same. Does this discussion ring a bell with
anyone?
Alternatively, if someone can take this as a challenge to make a
really creative SPARQL query, I'd be grateful :-)
User:Jura has been steadily investigating matching paired birth+death
dates as they come up.
Completed investigations can be found here:
https://www.wikidata.org/wiki/Wikidata:Database_reports/identical_birth_and…
while a bot scans for new matches which it writes to
https://www.wikidata.org/wiki/Wikidata:Database_reports/identical_birth_and…
Unfortunately, because of the limits on template expansion, it's hard to
see the corresponding names. But there certainly are some confirmed
twins in there with quite similar names.
There are also some queries narrowed to particular first names or
particular professions at
https://www.wikidata.org/wiki/Wikidata:WikiProject_Data_cleaning/matched_bi…
That page hasn't been updated since the SPARQL service was very very
new, so the counts are now all probably way off.
One early case I remember was a sportsman that we had separate articles
on as a cricketer and as a footballer, until his career was cut short by
World War I. But I think he has now been merged on en-wiki.
I see we also currently have
https://en.wikipedia.org/wiki/Jack_Jenkins_(rugby_player)
https://en.wikipedia.org/wiki/John_Jenkins_(rugby_league)
-- though the dates on the latter have been questioned.
Hope this helps,
James.
