I have a huge database of Japanese words and want to split them into flashcard decks of different difficulty levels. (actually for a GSoC project)
For this, I need to know the "difficulty" of each Japanese word.
Difficulty of a word is not easy to define, but it is probably a mix of:
- Level of study needed to understand the signified meaning
- Rarity of the signifier in litterature
- Rarity of each character in the signifier
- Length of the signifier
