Hoi,
Much of the content of DBpedia and Wikidata have the same origin; harvesting data from a Wikipedia. There is a lot of discussion going on about quality and one point that I make is that comparing "Sources" and concentrating on the differences particularly where statements differ is where it is easiest to make a quality difference.
So given that DBpedia harvests both Wikipedia and Wikidata, can it provide us with a view where a Wikipedia statement and a Wikidata statement differ. To make it useful, it is important to subset this data. I will not start with 500.000 differences but I will begin when they are about a subset that I care about.
When I care about entries for alumni of a university, I will consider curating the information in question. Particularly when I know the language of the Wikipedia.
