Key nodes mining of root network and phoneme network of modern Chinese characters

Roots and phonemes are two important ingredients ( but not independent ones) when learning the Chinese language. In order to optimize the learning strategy, various key nodes mining algorithms are implemented both in the root network (RN) and phoneme network (PN) of modern Chinese characters. The lists of important roots and phonemes, and eventually the important characters are dug out and suggested. Rather than the commonly used frequency dictionary of characters, one would find that results from the key nodes mining are more systematic. Moreover, roots and phonemes are studied from perspective of the multi-layer network, in the interest of exploring the correlation between them, which are also very useful when learning the Chinese language.
