Slavic UD Treebanks with Periphrastic Verb Forms

This dataset is based on Universal Dependencies v2.16 (http://hdl.handle.net/11234/1-5901). It contains treebanks for 15 Slavic languages, enriched with periphrastic verb form annotations. While UD encodes morphological features at the token level, our annotation extends this by marking periphrastic verb phrases that span multiple tokens — possibly discontinuously — to capture more complex verbal constructions. This kind of annotation is added to the last column of the CoNLL-U format (MISC). The added annotation is encoded in Phrase* attributes in MISC. In certain cases, the annotation of FEATS and DEPREL was modified, too, to provide more uniform annotation across the languages.
