# UD_Japanese-KTC
This treebank is produced by automatically converting Kaede treebank,
which is built over the source material of Kyoto corpus.
http://nlp.ist.i.kyoto-u.ac.jp/EN/index.php?Kyoto%20University%20Text%20Corpus
## Recovering data
The data is provided in the CoNLL format, but original texts are
stripped off due to the license issue. In order to recover the data
with original texts, you need the corpus of Mainichi Shinbun 1995 (the
same set of data for Kyoto Corpus). The Mainichi Shinbun data can be
obtained from Nichigai Associates:
http://www.nichigai.co.jp/sales/mainichi/mainichi-data.html
The corpus is obtained by running the following command:
./autoconv -d MAINICHI_DIR
where `MAINICHI_DIR` denotes the directory of the files of Mainichi
Shinbun 1995. In order to run this command, you need Perl and
Python.
The program for extracting texts from Mainichi Shinbun 1995 is
borrowed from the Kyoto Corpus project.
## Spliting
Each data set contains UD annotations for the following sections in Kyoto Corpus.
training: articles from January 1st to 4th and editorials from January to February
development: articles on January 6th and editorials in April
test: articles on January 5th and editorials in March
