Wikidata is a great project towards mapping structured information about the world, and exhibits a high degree of correctness. Its degree of completeness, in turn, is much less understood. Anecdotal evidence suggests that it covers many popular topics quite well, but there are few standard means that help in this assessment: At present, editors and consumers have to analyze largely on a case-by-case basis whether given information might be complete or not. This session concerns the automated assessment of the completeness of Wikidata, and consists of two parts:
In the first 30 minutes I will survey techniques to assess the completeness of parts of Wikidata, in particular (i) mandatory properties (like P1963), (ii) explicit assertions of completeness via COOL-WD, (iii) comparative completeness using Recoin, and (iv) tabular views like discussed here. I will briefly introduce each technique and discuss its advantages and limitations.
The second part of the session (15 minutes) shall be an open discussion, guided by the questions
- What kind of (anecdotal) knowledge about completeness of parts of Wikidata do participants have?
- What kind of structured knowledge about completeness would participants like to obtain?
- What tools could help towards this?
- What will attendees take away from this session?
- Awareness of completeness as multidimensional concept
- Knowledge of the existing tools for assessing the completeness of Wikidata, their potential and their limitations
- Hopefully a roadmap how completeness of Wikidata will be made more transparent in the future
- Slides or further information
- Special requests

- Would love to see these tools applied systematically to some example areas (e.g. the Zika corpus), and over time. Daniel Mietchen (talk) 07:19, 31 July 2017 (UTC)
