Abstract

Collaborative knowledge bases that make their data freely available in a machine-readable form are central for the data strategy of many projects and organizations. The two ma- jor collaborative knowledge bases are Wikimedia’s Wikidata and Google’s Freebase. Due to the success of Wikidata, Google decided in 2014 to offer the content of Freebase to the Wikidata community.
In this paper, we report on the ongoing transfer efforts and data mapping challenges, and provide an analysis of the effort so far. We describe the Primary Sources Tool, which aims to facilitate this and future data migrations. Throughout the migration, we have gained deep insights into both Wikidata and Freebase, and share and discuss detailed statistics on both knowledge bases
