Kaede treebank is a Japanese constituent treebank, which has clause level annotations with syntactic function labels, e.g., syntactic role and clause type, and coordinated construction. The treebank is designed to have complete binary trees, and is currently composed of about 10,000 sentences from the Kyoto University Text Corpus (the Mainichi Shimbun Newspaper).
Due to the copyright issue, this repository provides only annotations, and does not include original raw text data. In order to obtain a treebank with original raw texts, follow this procedure.
