org.omegat.tokenizer.LuceneSmartChineseTokenizer

All Implemented Interfaces:

ITokenizer

public class LuceneSmartChineseTokenizer
extends BaseTokenizer

LuceneSmartChineseTokenizer is a tokenizer class for handling Chinese text processing using the SmartChineseAnalyzer or HMMChineseTokenizer from the Lucene library. This class is specifically designed for scenarios requiring tokenization of Chinese text, either with or without stemming and stop word filtering.

This tokenizer is intended to tokenize input strings either by code points or by utilizing Lucene's token stream processing. It overrides methods to cater to verbatim tokenization needs, addressing issues with punctuation replacement in the SmartChineseAnalyzer when dealing with verbatim scenarios.
