      public class HMMChineseTokenizer
      extends SegmentingTokenizerBase

  Tokenizer for Chinese or mixed Chinese-English text.

  The analyzer uses probabilistic knowledge to find the optimal word segmentation for Simplified Chinese text. The text is first broken into sentences, then each sentence is segmented into words.
