Summary
UD_Polish-MPDT is a treebank of Middle Polish (17th–18th centuries). It is a rule-based conversion of the Middle Polish Dependency Treebank (Wieczorek, 2025) from its original annotation to the Universal Dependencies format. The MPDT sentences are sourced from the KorBa corpus (Gruszczyński et al., 2022).
Introduction
The UD_Polish-MPDT treebank contains sentences from the Middle Polish period (17th–18th centuries). The material is drawn from the KorBa corpus – The Electronic Corpus of 17th- and 18th-century Polish Texts – a large and diverse collection of Polish literature, scientific texts, official documents, press releases, and more from 1601–1772.
The syntactic annotations originate from the Middle Polish Dependency Treebank, a project led by Aleksandra Wieczorek, which adds a dependency layer to a selected part of KorBa. The original MPDT annotation follows the conventions of the Polish Dependency Bank (PDB).
This initial UD release contains 2,018 sentences and approximately 47K tokens, with plans for further expansion in future versions.
