07 Universal Dependencies
Universal Dependencies (UD) is an internationally harmonised annotation framework that aims to standardize the morphological and syntactic tagging of texts across languages in order to foster the development of multilingual language technologies and contrastive linguistics research. Grounded in dependency grammar principles, UD provides a universal set of grammatical categories – including parts of speech (POS), morphological features and syntactic dependency relations – and guidelines for their use. The framework is flexible, incorporating language-specific tags as needed. To date, over 240 corpora worldwide have been manually tagged using the framework, including the universal treebanks of both written and spoken Slovene.
Introduction to Tags
The Universal Dependencies framework establishes a comprehensive and universal set of tags for parts of speech (POS), morphological features and syntactic dependencies that can be adopted in the treebanks of individual languages, or supplemented with new morphological features or derivations of core relations when necessary. For the Slovene language data, this includes the adoption of all 17 parts of speech (see Table 1), 22 morphological features spanning 62 distinct values (see Table 2), and 35 types of dependency relations (see Table 3).
