You have been adding the (unsourced and vague) information that a number of scientists were indeed scientists. This is useless when the precise subject(s) are already here. Moreover in the French Wikipedia (and in other langages as well) the template « Biographie2 » directly imports assertions from wikidata in the infobox. In the case of Johann Euler your addition presented him as « Mathématicien, astronome, physicien, scientifique » , the last precision being of course redundant and totally useless (and weird). ]reply[20:17, 19 January 2020 (UTC)) talk (Lewoniewski (not directly in class "scientist").--Q188094I putted example below (SPARQL query), to show why this approach is incomplete and sometimes can give wrong results. I didn't find the list of "general" classes that can be not added to Wikidata items when there is some specific subclass. Also there is a question about classes that are not presented in those general classes: for example ]reply[11:02, 19 January 2020 (UTC)) talk (SapphorainI already mentioned the problem twice: in the French wikipedia (as well as in other langages), such an addition will suddenly provoque the appearance of the same addition in the list of various occupations of a scientist in his infobox. For instance such-and-such will not only be be reputed to be a mathematician, a physicist, and a biologist, but as well a .... scientist. This is inappropriate as well as ridiculous. ]reply[10:22, 19 January 2020 (UTC)) talk (LewoniewskiCan you precise - what is the problem? -- ]reply[10:17, 19 January 2020 (UTC)) talk (SapphorainI don't know.

This thus provides little improvement, but creates a problem that must then be corrected individually.

Again, by adding ]reply[09:42, 19 January 2020 (UTC)) talk (LewoniewskiI am not agree with you. Sometimes people searching for scientists and they must be able to do it based on one "class" (otherwise they need to know about over 100 others class names). If we will think in your way, why we don't delete "human" alignment if somebody is an economist? --: Q901or descendants of (Q901)scientist (P106)occupation SPARQL is specifically designed to enable one to find all items with
