| 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 currently used in: |

Polish Dependency Bank 2.0 (PDB 2.0)
PDB 2.0 is an extended version of Składnica treebank. It consists of 22,208 trees and 351,175 tokens (i.e. 15.8 tokens per sentence on average). There are four parts of PDB 2.0:
- NKJP1M trees (14K)
- PDB_projected trees (4K)
- CDScorpus-based trees (2K)
- OTHER trees (2K)
The PDB sentences 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.
PDB data
The updated version of Składnica zależnościowa (the previous version of PDB).
If you wish to get the entire PDB corpus (22K sentences annotated with the dependency trees) please contact alina <at> ipipan.waw.pl (replace <at> with @).
PDB relation types
Descritptions of Polish dependency relation types are at http://zil.ipipan.waw.pl/PDB/DepRelTypes (outdated).
Polish Dependency Bank in Universal Dependencies format (PDBUD)
PDBUD is a conversion of PDB into the UD-like format. It is an extended and corrected version of the Polish UD treebank (the release 2.1). PDBUD contains enhanced graphs, i.e. trees with 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 were 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)
PDBUD data
PDBUD is publicly available on http://git.nlp.ipipan.waw.pl/alina/PDBUD
