For example, I would like to find all articles in [[Kategorie:Maschinelles_Lernen]] which have issues. One issue are missing sources. Articles with this kind of issue are in Kategorie:Wikipedia:Belege fehlen.

There is at least one in both (Global Network of Dreams), however, when I use catscan2 it seems not to find it.

How can I get a list of all Wikpedia articles within [[Kategorie:Maschinelles_Lernen]] which have obvious issues?

By using the parameter incategory in the searchbox you can do it, but you have to do it for each combination of the issues you are looking for. This will be solving your example:


What I actually typed in the search box was:

incategory:"Maschinelles Lernen" incategory:"Wikipedia:Belege fehlen"
  • Do you have an idea how to get all articles with quality problems? Commented Dec 6, 2015 at 15:40
  • Not in one single search. You would have to do it for each category of the quality problems you are interested in.
