Disclaimer: We estimate that this release contains errors in as many as 5% of entries. We decided to spend more effort in increasing the cover than in checking. As we translate the glosses and sense tag text, we expect to fix many of the errors. The definitions and examples are translated from English and may not match the synsets exactly.
We welcome feedback.

This is a partially sense tagged corpus of Japanese. It was created by translating the SemCor corpus, and transferring the tags from English to Japanese (Bond et al. 2012). It is released under the same license as the Japanese Wordnet.
Japanese WordNet Synonyms Database is a collection of 11,753 synonym pairs, which were created using synsets in Japanese WordNet version 1.1. Word pairs were generated using words in a synset, which is a cluster of words that share the same sense. Then, only word pairs that were manually annotated as synonym pairs were included in the database. For instance, under synset 00623862-n, there are words such as 'izakoza, komarimono, koshoo, toraburu'. From this list of words, we created pairs such as 'izakoza/komarimono', 'izakoza/koshoo', 'izakoza/toraburu'. From the word pairs, only the ones that were manually annotated as a synonym pair such as 'izakoza/toraburu' were included in the database. For the detail, please refer to readme file (readme.e.ver.1.0.pdf) attached with the data.
