# Summary

Universal Derivations version of Czech derivational relations extracted from Etymological WordNet (http://www1.icsi.berkeley.edu/~demelo/etymwn/).


# Introduction

The Etymological Wordnet project provides information about how words in different languages are etymologically related. The information is mostly mined from the English version of Wiktionary (http://en.wiktionary.org/), but also contains a number of manual additions.

Derivational relations for Czech were extracted from Etymological WordNet and harmonized manually.


# Acknowledgments

We wish to thank all of the developers of the Etymological WordNet, including Gerard de Melo, and Gerhard Weikum.
