分词系统的原理是基于词典匹配进行分词，就是说它会先去文件的一行，在去这行中的四个字然后去和词典比较，如果词典中有这个字则输出加空格，如果没有则把左边的字去除剩下3个字后再和词典进行比较-The principle of word segmentation system is based on word segmentation dictionary matching, which means it will go first to file a line, in the four words in the line and then go and dictionaries, if have the words in the dictionary is output to add Spaces, if not remove the remaining on the left side of the word and dictionary again after more than three words
