CounQER: {Coun}ting {Q}uantifiers and {E}ntity-valued P{R}edicates
Predicate constraints of general-purpose knowledge bases (KBs) like Wikidata, DBpedia and Freebase are often limited to subproperty, domain and range constraints. CounQER is a two-step approach, which
- identifies set-valued predicates from a given KB predicates via statistical and embedding-based features, and
- links counting predicates and enumerating predicates by a combination of co-occurrence, correlation and textual relatedness metrics.
in order to dicover the alignment of counting predicates, like staffSize
, and enumerating predicates, like workInstitution-1
.
