  61. 61. Wikidata knows about Wikipedia categories. NEDERLAND Currently there are items for 2,406,128 categories. Many of those items refer to categories in multiple Wikipedias. One random example is item Q8884100, it refers to categories in 10 Wikipedias. All of them categorize people who studied at the university of Notre Dame. Many of them know about people only known in that Wikipedia. In addition to this there may be articles that are not categorised or references to articles that are not in one of the 10 categories known at this time. http://ultimategerardm.blogspot.nl/2014/11/wikidata-wikipedia-categories.html
  62. 62. NEDERLAND When multiple categorised are "harvested" in Wikidata, Wikidata knows about more items than any of the individual categories. This enables the use of the data in new ways. • suggest categories based on the presence of statements in the Wikidata category • suggest statement when an article is included in a category • include red links in a category when a Wikipedia does not have articles. http://ultimategerardm.blogspot.nl/2014/11/wikidata-wikipedia-categories.html
