I don't have generic good pointers but a few interesting things I read or downloaded:
- https://aclanthology.info/pdf/I/I05/I05-7002.pdf This paper make use of the radicals to build an ontology, but it does so with a stunting amount of depth (historical context, variants, etc.) that most works overlook. Too bad no data is available.
Anyway, I think for getting a fair understanding of the writing system the learning of about 600 characters in either Chinese or Japanese + basic of the chosen language is required.
