Summary
The Czech-PDTC UD treebank is based on the Prague Dependency Treebank – Consolidated (PDT-C) 2.0, created at the Charles University in Prague.
Introduction
PDT-C is a collection of four treebanks that were previously released independently and that are now enhanced with further manual linguistic annotation:
- PDT: The original Prague Dependency Treebank, based on texts from daily newspapers, a business weekly, and a popular science magazine, all from 1990s.
- PCEDT: The Czech part of the Prague Czech-English Dependency Treebank. The texts are Czech translations of the Wall Street Journal data in the Penn Treebank.
- PDTSC: Prague Dependency Treebank of Spoken Czech. It contains transcriptions of spontaneous dialogs from the Malach and Companions projects.
- Faust: A small dataset prepared for the Faust project. It contains user-generated Czech translations of English sentences, created during testing a machine translation system.
The treebank consists of 3.4 M tokens. It is licensed under the terms of CC BY-NC-SA 4.0 and its original (non-UD) version can be downloaded from http://hdl.handle.net/11234/1-5813.
The morphological and syntactic annotation of the Czech UD treebank is created through a conversion of PDT-C data. The conversion procedure has been designed by Daniel Zeman and implemented in Treex.
