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 https://qwikidata.readthedocs.io/en/stable/readme.html#json-dump . You can contact me off the mailing list if you would like help using the package. best, -Gabriel
