Hello Fariz,

many thanks for the nice tool, useful also to find which properties are probably missed on which entities.

If you want to work on it further: I think, the graph is a bit inexact, maybe just at the 10%-percentile. One can compare with

https://en.wikipedia.org/wiki/Gini_coefficient#/media/File:Lorenz_curve_global_income_2011.svg

Best regards Michal

We are releasing the alpha version of Wikidata Knowledge Imbalance
Dashboard (https://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fprowd.netlify.com%2F&data=01%7C01%7Cmichal.pavlovic%40newayselectronics.com%7C2db09ae9ef9b4c36951808d7cfeb1f57%7Cec7e8b70c75743cc90e8805ad967f616%7C1&sdata=8zBIeqGbb5Vkcp0zt8mluyeNKyIWxAyA063agv0IUOQ%3D&reserved=0). 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://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fprowd.netlify.com%2F&data=01%7C01%7Cmichal.pavlovic%40newayselectronics.com%7C2db09ae9ef9b4c36951808d7cfeb1f57%7Cec7e8b70c75743cc90e8805ad967f616%7C1&sdata=8zBIeqGbb5Vkcp0zt8mluyeNKyIWxAyA063agv0IUOQ%3D&reserved=0 , and welcome any constructive feedback!

Regards,
Fariz
