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 .
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
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
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 .
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
screenshot at .
- Query completeness diagnostics: give an explanation (which completeness
statements are used, and how) whenever (in)-complete query answers are
), example screenshot at .
- Linked data publication of completeness statements, for instance, RDF
description of the completeness statement of all cantons in Switzerland:
- 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 .
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! Our COOL-WD project chat is also
