We are releasing the alpha version of Wikidata Knowledge Imbalance Dashboard (https://prowd.netlify.com/). The tool measures knowledge imbalances on Wikidata using Gini index based on property existence over entities.

In the examples, data about infectious diseases [1] is shown to be imbalanced (Gini = 0.26), whereas data about countries [2] is balanced (Gini = 0.14). Other examples include programming languages [3] (Gini = 0.37) and association football clubs [4] (Gini = 0.29).

The tool also supports the scenario where instead of analyzing all possible properties of entities, one may focus on specific properties of interest. With respect to diseases [5], for example, analyzing the existence of the properties has effect (P1542), possible treatment (P924), drug used for treatment (P2176), and symptoms (P780), reveals that Wikidata is heavily imbalanced.

As the tool is still in a preliminary stage, we invite you to give it a try at https://prowd.netlify.com/ , and welcome any constructive feedback!
