Hi,
CogNet uses data from the Japanese wordnet (and many others). For example, the fact that
ポリプロピレン links to 14996158-n comes from there:
https://compling.upol.cz/ntumc/cgi-bin/wn-gridx.cgi?gridmode=wnja
The Japanese wordnet requires that any copies include its license:
https://bond-lab.github.io/wnja/license.txt
Further, this license, and the license for wiktionary (CC BY-SA) are incompatible with CC BY-NC-SA.
Can you properly acknowledge the data you are using and make sure the licensing is legal?
