Wikidata defines domain and range constraints for its drug used for treatment
(
P2176)<https://www.wikidata.org/wiki/Property:P2176> property, which seems like a
nice probabilistic compromise compared to description logic.

If the property is misused, the system will report constraint violations in the UI and in
reports:

Subject: [External] Re: [Wikidata] Important, Critical issues related to Wikidata
Dear Sir,
I thank you for your answer. I thank you as well for your comments. Concerning the
description logics layer, it is mainly needed to find inconsistency or disagreement
between Wikidata statements. As I had shown in Wikimania 2019, if X is a drug for Y and Y
is a drug for X then one of these two defined statements is wrong. Concerning the ontology
for the stages of diseases, it can be involved if I have a research paper as a reference
for each Wikidata statement.
Yours Sincerely,

2. .I ask if Wikidata can involve a description logics layer for properties that can be
later used to find data inconsistencies within Wikidata.
This exactly one of the use cases we use ShEx for, i.e. inconsistency or disagreement
between resources. Wikidata does not reflect the true, but (partly) reflect what other
resources describe on a selected matter. There are many examples of Wikidata where
different items state opposite statements. This is fine. Any issue known on Wikidata,
provided the references are correct and the values are not distorted in the ingestion
process, basically needs to be discussed with the primary source, not with Wikidata. ShEx
provides the instrument to identify items relevant to your view, versus items disagreeing
with your view on the matter.
4. We should either change CC-0 into CC-BY Licence or try to convince the creators of
ontologies to change the licence of their works into CC-0.
I am excited you are joining us in our quest for more CC0 data. More and more data is
adopting the CC0 license. I really like the following blog on the matter
https://osc.universityofcalifornia.edu/2016/09/cc-by-and-data-not-always-a-…
7. I think that we should be an ontology for the stages of diseases.
Wikidata is not a primary source, point me to a ontology of stages of disease and I will
add it to wikidata.
