In addition, to illustrate its effectiveness, we compare it with two publicly available confusion sets (Liu et al., 2009), Con1 and Con2.
con1 consists of Sc (similar cangjie), SSST (same-sound-same-tone) and SSDT (samesound-different-tone), while con2 consists of all sets, Sc, SSST, SSDT, MSST (similar-sound- Tst   same-tone) and MSDT (similar-sound-differenttone).
