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:

1. NKJP1M trees (14K)
2. PDB_projected trees (4K)
3. CDScorpus-based trees (2K)
4. 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 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

PDB-based parsers

Some dependency parsing models estimated on PDB are available at http://zil.ipipan.waw.pl/PDB/PDBparser
