# 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 ## Citation You are encouraged to cite the following paper when you refer to the Universal Dependencies Japanese Treebank.
