Polish Dependency Bank in Universal Dependencies format (PDBUD)

PDB is an extended version of Składnica" treebank. Since the UD conversion of "Składnica" trees constitutes the Polish treebank in Universal Dependencies collection (the release 2.1), PDBUD is thus an extended and corrected version of this treebank.

The converted PDBUD trees are largely consistent with Polish UD trees. Składnica trees are rather simple and the sentences underlying this data set do not contain some linguistic phenomena, e.g. ellipsis, comparative constructions, constructions with the bi-functional subordinating conjunction "jako", directed speech, interpolations and comments, nominative noun phrases used in the vocative function and many others. Therefore, the repertoire of UD relation subtypes and language-specific features is slightly extended to cover these phenomena. Furthermore, PDBUD trees contain enhanced edges encoding shared dependents of coordinated elements, e.g. "Dziewczynka śpiewa i tańczy. (The girl sings and dances.), and shared governors of coordinated elements, e.g. "Dziewczynka i chłopiec śpiewają. (A girl and a boy sing.)

PDBUD trees are used in:

Shared task on automatic identification of verbal multiword expressions (LAW-MWE-CxG-2018)

Shared task on dependency parsing of Polish (PolEval 2018, [[http://poleval.pl]])

Data

Note! As PDBUD data are used in PolEval 2018, test data are currently not publicly available.
