Description

The Czech-PDT UD treebank is based on the Prague Dependency Treebank 3.0 (PDT), created at the Charles University in Prague.

The treebank consists of 87,913 sentences (1.5 M tokens) and its domain is mainly newswire, reaching also to business and popular scientific articles from the 1990s. The treebank is licensed under the terms of CC BY-NC-SA 3.0 and its original (non-UD) version can be downloaded from http://hdl.handle.net/11858/00-097C-0000-0023-1AAF-3.

The morphological and syntactic annotation of the Czech UD treebank is created through a conversion of PDT data. The conversion procedure has been designed by Dan Zeman and implemented in Treex.
