CounQER: A System for Discovering and Linking Count Information in Knowledge Bases [article]

Shrestha Ghosh, Simon Razniewski, Gerhard Weikum
2020 arXiv   pre-print
In this demo we showcase CounQER, a system that illustrates the alignment of counting predicates, like staffSize, and enumerating predicates, like workInstitution^-1 .  ...  Predicate constraints of general-purpose knowledge bases (KBs) like Wikidata, DBpedia and Freebase are often limited to subproperty, domain and range constraints.  ...  Detecting inter-predicate relations in Knowledge Bases (KBs) beyond inheritance can lead to a better semantic understanding that can be leveraged for important tasks such as KB curation and question answering  ...

Uncovering Hidden Semantics of Set Information in Knowledge Bases [article]

Shrestha Ghosh, Simon Razniewski, Gerhard Weikum
2020 arXiv   pre-print
We analyze the prevalence of count information in four prominent knowledge bases, and show that our linking method achieves up to 0.55 F1 score in set predicate identification versus 0.40 F1 score of a  ...  Knowledge Bases (KBs) contain a wealth of structured information about entities and predicates.  ...  This paper presents CounQER (for "Counting Quantifiers and Entity-valued PRedicates"), the first comprehensive methodology towards identifying and linking set predicates in KBs.  ...
