This dataset contains the results of a computational operationalization of Greenberg's Universal 45 applied to the Universal Dependencies (UD) corpus (version 2.14). The data covers 339 treebanks across 186 languages. For each treebank and Universal POS tag (UPOS) category, the dataset records whether gender distinctions are present in singular and/or plural tokens, and whether this combination constitutes a violation of the implication universal. The dataset also includes aggregated counts of gender-marked tokens by treebank, language, and UPOS category.
