Hey all, Is anyone aware of research on the completeness of Wikidata, in terms of coverage and systemic bias? This seems like the sort of thing Max Klein might know ;). Papers, blog posts, anything. -- Oliver Keyes Research Analyst Wikimedia Foundation

Hi Oliver, from the top of my head, two on gender coverage: the one Max just sent around: http://ijoc.org/index.php/ijoc/article/view/777/631 and another one, with a different approach, but a similar goal: http://arxiv.org/abs/1501.06307 We had one on diversity that also has a small section about representativeness of the editor base, although it might not be exactly what you are looking for: http://journal.webscience.org/432/1/112_paper.pdf Gruß, Fabian On 07.04.2015, at 21:50, Oliver Keyes <okeyes@wikimedia.org<mailto:okeyes@wikimedia.org>> wrote: Hey all, Is anyone aware of research on the completeness of Wikidata, in terms of coverage and systemic bias?

Thanks both! I'm specifically looking at Wikidata's coverage, rather than Wikipedia's - in other words, work done on deficiencies in the mapping of wikimedia content onto wikidata content. On 8 April 2015 at 07:19, Flöck, Fabian <Fabian.Floeck(a)gesis.org> wrote:

Oh, I didn't see it was Wikidata instead of Wikpedia. Wikipedia research and tools: Review and comments. http://www2.compute.dtu.dk/pubdb/views/edoc_download.php/6012/pdf/imm6012.p… contains pointers to the Max Klein/Piotr Konieczny studies and Magnus Manske's Mix’n’match (presently page 11). Magnus Manske has a blog post recently: http://magnusmanske.de/wordpress/?p=278 "Sex and artists" If I remember correctly wikidata-l had some discussion about that. Probably you know that already. best Finn Årup Nielsen
