Summary

FicTree is a treebank of Czech fiction, automatically converted into the UD format. The treebank was built at Charles University in Prague.

Introduction

The treebank consists of 12,760 sentences (166,432 tokens). The texts come from eight literary works published in the Czech Republic between 1991 and 2007. The text data was manually annotated according to the Prague Dependency Treebank guidelines, then converted into the UD format. To comply with agreements concluded with the copyright holders, the texts are shuffled into random chunks of maximum 100 words. The treebank is licensed under the terms of [CC BY-NC-SA 3.0] (http://creativecommons.org/licenses/by-nc-sa/3.0/).

Annotation and conversion

The texts were parsed independently by two parsers trained on the Prague Dependency Treebank data (analytical layer). The parsing results were manually corrected and the two versions merged. Any differences were resolved manually. The morphological and syntactic annotation according to the UD guidelines was assigned by converting the original PDT annotation. The conversion procedure was designed by Dan Zeman and implemented in Treex.

Acknowledgments

We wish to thank the participants in the annotation effort, including Milena Hnátková, Tomáš Jelínek, Ivana Klímová, Alena Kropíková, Hana Skoumalová and Olga Zitová; as well as Dan Zeman for the data conversion.

Text details

The eight texts in the treebank include six fiction titles, a children’s fiction book, and a book of memoirs. Most of the texts were first published between 1991 and 2007 except one text, published in 1969. 80% of the texts are original Czech texts, 20% are translations (from German and Slovak).
