Dear Sir,
I thank you for your efforts. When dealing with biomedical taxonomic statements jn
Wikidata, we found similar deficiencies. I have already decided to write a paper about the
biomedical taxonomy of Wikidata and how to adjust it. I will be honoured if you can be the
first author of the work. You have already extracted the taxonomic statements. So, you can
easily filter the biomedical ones. This work has already been done for other taxonomies
such as SNOMED-CT
(

available online for further discussion if you agree to work with our team. This will be
simple.

Thanks Jan, I will pursue the badminton discussion on the talk page.

Hello Gabriel,
I agree with you about the badminton tournaments, that seems odd. It appears to already be
a discussion about that on the talk page of the only participant in the badminton project:
https://www.wikidata.org/wiki/User_talk:Florentyna#subclass_of:_badminton_t…
Perhaps it is best to continue the discussion there?

Hello everyone,
I was playing around with a recent wikidata dump and extracted the items that
"looked" like classes based on the definition here,
https://www.wikidata.org/wiki/Wikidata:WikiProject_Ontology/Classes
Specifically, an item is a class-item if any of the following are true,
* the item is the value of a P31 ("instance of") statement
* the item has a P279 ("subclass of") statement (subclass)
* the item is the value of a P279 ("subclass of") statement (superclass)
Once I extracted all items that met these criteria (2,399,621 items from
wikidata-20190603-all.json.bz2) I started examining the results. One of the things I
found slightly surprising is that there are about 23k badminton events that are classes
b/c they have "subclass of
https://www.wikidata.org/wiki/Q13357858" statements.
SPARQL query below.
https://query.wikidata.org/#SELECT%20%3Fitem%20%3FitemLabel%20%0AWHERE%20%0…
It also looks like there is a badminton project page,
https://www.wikidata.org/wiki/Category:WikiProject_Badminton
https://www.wikidata.org/wiki/Wikidata:WikiProject_Badminton/Subclass
I'd like to remove these statements as it seems that a particular instance of a
badminton tournament
https://www.wikidata.org/wiki/Q121940
is not a class.
It seems that this pattern is also in place for about 1,000,000 items which are instance
of gene (e.g.
https://www.wikidata.org/wiki/Q40108).
I had a couple questions for the mailing list,
1) do folks know if there is an active group working on wikidata ontology
2) i've read a few messages about shape expressions. would it be worthwhile to setup
a shape expression that prevents most items from having both "instance of" and
"subclass of" statements?
3) if these entries are generated by bots, what is the best way to get in touch with the
owner, their user talk page?
I am probably missing a lot of information about what has been done so far in the
community, but I'm happy to read anything someone points me towards.
best,
-Gabriel
