This repository presents two resources:
- D3J, the Dictionary Definition Dataset for Japanese. D3J provides lexically simple definitions for 325 Japanese headwords, created in collaboration with a professional lexicographer.
- TUBE16K, a defining vocabulary used for building D3J. TUBE16K consists of (1) the 16,000 most frequent words from the Japanese section of the TUBELEX corpus, and (2) linguistic terms to concisely describe meanings or usages of headwords. Note that words in TUBE16K are SUWs (short unit words).
Details of D3J and TUBE16K are described in our paper. Consider citing it when using the resources.
