Project: Improving knowledge graph completeness with schemas: Wikidata and ShEx

Description

In the collaboratively built knowledge base Wikidata some editors would appreciate suggestions of how to improve the completeness of items. Currently some community members use an existing tool, Recoin, described in this paper, to get suggestions of relevant properties to use to contribute additional statements. This process could potentially be greatly improved by leveraging the knowledged captured in prexisting schemas. We propose to study and develop extensions to Recoin that would generate relevant properties based on a ShEx schema from Wikidata’s schema namespace.

This work will help improve the quality and completeness of Wikidata, as a global open knowledge resource for humanity.
