This workshop focuses on presenting and showing how to use the tools included in the Wikidata Quality Toolkit (WQT). The WQT consists of tools, built on top of recently published research, that aim at assisting Wikidata editors in three of their daily tasks: recommending editors what items to edit (based on their expertise and edit history); detecting item references that do not support claims well (and ways of improving them); and automatically generating EntitySchemas to find items with missing information. We will demonstrate these tools, help editors in using them, and gather feedback for further improvement.
