Dear Wikidata community, we are happy to announce the next release of COOL-WD: a Completeness Tool for Wikidata, packed with new features, inspired by the engaging discussion with you all on the first release [1]. The main purpose of COOL-WD is to allow to create and manage completeness information about Wikidata, such as "Complete for all Switzerland's cantons" and "Complete for all of Obama's children". While previously one had to access an external tool to add and view Wikidata completeness information at http://cool-wd.inf.unibz.it/, now a user script is available to enable adding and viewing completeness information directly inside Wikidata [2]. When the script is enabled, properties annotated as complete are marked by a green box, while all other properties are marked in yellow. To state that a certain property is complete, one can simply click on the yellow box to make it turn green. To add a reference URL for the completeness, one can click the small '(i)' icon next to the property name to add the reference URL. An example screenshot is available at [3]. Several other new features are: - Completeness analytics: show the progress in data completion wrt class of objects of interest (http://cool-wd.inf.unibz.it/? p=aggregation), example screenshot at [4]. - Query completeness diagnostics: give an explanation (which completeness statements are used, and how) whenever (in)-complete query answers are given (http://cool-wd.inf.unibz.it/?p=query), example screenshot at [5]. - Linked data publication of completeness statements, for instance, RDF description of the completeness statement of all cantons in Switzerland: http://cool-wd.inf.unibz.it/resource/statement-Q39-P150 - RDF dump of over 10,000 completeness statements in COOL-WD collected from various sources: http://completeness.inf.unibz.it/rdf-export/ Last but not least, a description of these features is to appear as a paper at COLD 2016 Workshop, which currently can be downloaded [6]. The tool is still a prototype, so we very much look forward to your feedback regarding how useful you consider the tool, and your ideas for conceptual or technical improvements!
