Wikidata problems to be soloved

Wikidata is a collaboratively edited multilingual knowledge graph hosted by the Wikimedia Foundation, which is founded in late 2012, 8 years ago. At the time of writing, Wikidata currently contains 93,647,881 items. 1,422,596,352 edits have been made since the project launch.

Wikidata recenly has growing interests with more dedicated events such as Wikidata Workshop @ISWC or Wiki Workshop @WWW. A recent systematic literature review by Marçal Mora-Cantallops et al. - "A systematic literature review on Wikidata" - also summarizes the research efforts in the context of Wikidata nicely.
