  Predicate constraints of general-purpose knowledge bases (KBs) like Wikidata,
DBpedia and Freebase are often limited to subproperty, domain and range
constraints. In this demo we showcase CounQER, a system that illustrates the
alignment of counting predicates, like staffSize, and enumerating predicates,
like workInstitution^{-1} . In the demonstration session, attendees can inspect
these alignments, and will learn about the importance of these alignments for
KB question answering and curation. CounQER is available at
https://counqer.mpi-inf.mpg.de/spo.
