In the last years, many knowledge bases have been developed and used in real-world applications. These include DBpedia, Wikidata, and YAGO which all cover general knowledge and therefore similar topics. In this poster, we present statistical measurements on these KBs. Our experiments reveal that despite that fact that these KBs cover the same domains to a considerable amount, they differ from each other significantly w.r.t. their graph-based structure and ontological aspects.
