Class CJKTokenizer

CJKTokenizer is designed for Chinese, Japanese, and Korean languages.


The tokens returned are every two adjacent characters with overlap match.

Example: "java C1C2C3C4" will be segmented to: "java" "C1C2" "C2C3" "C3C4".

Additionally, the following is applied to Latin text (such as English):
  • Text is converted to lowercase.
  • Numeric digits, '+', '#', and '_' are tokenized as letters.
  • Full-width forms are converted to half-width forms.
