DescriptionBarriers to Using Wikidata as a Knowledge Base.pdf
English: ABSTRACT: At first glance Wikidata appears to be an excellent source of general background knowledge. It is large, contains generally high-quality information, contains a large ontology, and can be freely used. However, it is difficult to use Wikidata as a knowledge base of general-purpose information. The worst barriers to using Wikidata involve its ontology and qualifiers. More care in building and describing the ontology and more uniformity in modeling would go a long way to make Wikidata more useful as a source of knowledge.
