Abstract

Wikidata is a key resource for the provisioning of structured data on several Wikimedia projects, including Wikipedia. By design, all Wikipedia articles are linked to Wikidata entities; such mappings represent a substantial source of both semantic and structural information. However, only a small subgraph of Wikidata is mapped in that way – only about 10% of the sitelinks are linked to English Wikipedia, for example. In this paper, we describe a resource we have built and published to extend this subgraph and add more links between Wikidata and Wikipedia. We start from the assumption that a number of Wikidata entities can be mapped onto Wikipedia sections, in addition to Wikipedia articles. The resource we put forward contains tens of thousands of such mappings, hence considerably enriching the highly structured Wikidata graph with encyclopedic knowledge from Wikipedia.
