Open Knowledge Graphs (KGs) such as DBpedia and Wiki- data have been recognized as the foundations for diverse applications in the field of data mining and information retrieval. Each of these KGs fol- lows a different knowledge organization as well as is based on differently structured ontologies. Moreover, it has been observed that type informa- tion are often noisy, incomplete or even incorrect. In general, there is a need for well defined and comparable type information for the entities of the KGs. In this paper, we propose an isomorphism-based approach to infer subsumption relations to RDF type information in Wikidata by exploiting the RDF type information from DBpedia. Keywords: Knowledge Graph, RDF, Wikidata, DBpedia
