Thanks for the message Houcemeddine. I admire you optimism! I'm happy
that you're investigating biomedical taxonomic statements in Wikidata, but
I'm not interested in writing a paper right now. You can find examples of
working with the JSON dumps in the qwikidata python package I wrote here
. You can
contact me off the mailing list if you would like help using the package.
best,
-Gabriel

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 (

will be 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
