the examples of ud annotation just provided can of course give only an impression of the nature of the ud project and its annotation scheme. the emphasis for ud is on producing cross-linguistically consistent dependency analyses in order to facilitate structural parallelism across diverse languages. to this end, ud uses a universal pos tagset for all languages -- although a given language does not have to make use of each tag. more specific information can be added to each word by means of a free morpho-syntactic feature set. the universal labels of dependency links can be specified with secondary relations, which are indicated as a secondary label behind a colon, e.g. nsubj:pass, following the "universal:extension" format.
