Introduction

Prague Czech-English Dependency Treebank (PCEDT) 2.0 was developed by the Institute of Formal and Applied Linguistics at Charles University in Prague, Czech Republic. It is a corpus of Czech-English parallel resources translated, aligned and manually annotated for dependency structure, semantic labeling, argument structure, ellipsis and anaphora resolution. This release updates Prague Czech-English Dependency Treebank 1.0 (LDC2004T25) by adding English newswire texts so that it now contains over two million words in close to 100,000 sentences.

Data

The principal new material in PCEDT 2.0 is the inclusion of the entire Wall Street Journal data from Treebank-3 (LDC99T42). Not included from PCEDT 1.0 are the Readers Digest material, the Czech monolingual corpus, and the English-Czech dictionary.

Each section is enhanced with a comprehensive manual linguistic annotation in the Prague Dependency Treebank style (LDC2006T01, Prague Dependency Treebank 2.0). The main features of this annotation style are:

  • dependency structure of the content words and coordinating and similar structures (function words are attached as their attribute values)
  • semantic labeling of content words and types of coordinating structures
  • argument structure, including an argument structure (valency) lexicon for both languages
  • ellipsis and anaphora resolution

This annotation style is called tectogrammatical annotation, and it constitutes the tectogrammatical layer in the corpus.

Please consult the PCEDT website for more information and documentation.
