Wikidata’s class hierarchies provide crucial knowledge for building knowledge graphs. However, the hierarchy is so extensive that extracting the necessary class hierarchy is challenging. In this study, we develop a tool to efficiently extract class hierarchies by locally storing information on Wikidata class hierarchies in an index file.

Wikidata’s class hierarchies provide crucial knowledge for building knowledge graphs. However, the hierarchy is so extensive that extracting the necessary class hierarchy is challenging. In this study, we develop a tool to efficiently extract class hierarchies by locally storing information on Wikidata class hierarchies in an index file.
