COOL-WD: A Completeness Tool for Wikidata
The document introduces 'cool-wd', a tool designed for managing completeness information in Wikidata, which helps users determine which data is complete. It highlights the significance of completeness in knowledge bases, especially for increasing user trust and guiding editor focus. The tool currently hosts over 10,000 completeness statements that aid various applications, including query soundness checking.
