Wikidata and DBpedia: A Comparative Study

DBpedia and Wikidata are two online projects focused on offering structured data from Wikipedia in order to ease its exploitation on the Linked Data Web. In this paper, a comparison of these two widely-used structured data sources is presented. This comparison considers the most relevant data quality dimensions in the state of the art of the scientific research. As fundamental differences between both projects, we can highlight that Wikidata has an open centralised nature, whereas DBpedia is more popular in the Semantic Web and the Linked Open Data communities and depends on the different linguistic editions of Wikipedia.
