Abstract

Crowd based linked data knowledge bases like Wikidata allow their contributors to describe information without a schema and therefore in a wide variety of di-verse perspectives. This could potentially lead to lower data quality because there is less uniformity involved. Our research shows that despite fewer restrictions, there are some structures and patterns becoming apparent in regard to the predi-cates used to describe instances of specific classes like “countries”. We show how to use these structures and patterns to enhance the data quality of such knowledge bases in favour of the ...
