I'd like to download review scores (P444) for awards & prices, but only those with "review scored by" (P447) the "International Congress of Distinguished Awards" (Q58890465). See the Nobel Prize for a prize with two review scores. Is this possible?
If you mean doing this via the "Add column from reconciled values" functionality using the Wikidata reconciliation service, this is unfortunately not possible yet. Here is the ticket about it:
As a possible workaround you could query the Wikidata API directly, for instance via the
wbgetentities action, and then extract the required information out of the responses with GREL / Jython.
