CounQER: A System for Discovering and Linking Count Information in Knowledge Bases
This addresses the problem of enhancing knowledge base question answering and curation for users of systems like Wikidata, but it is incremental as it builds on existing predicate alignment concepts.
The paper tackles the limitation of predicate constraints in knowledge bases by introducing CounQER, a system that aligns counting and enumerating predicates, with results demonstrated through a live demo available online.
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.
