This paper analyses the actuality and introduces several different representative approaches of Chinese word segmentation, then brings out a character-position-based segmentation method which takes the Chinese character as the least unit.It indicates the probability distribution of a word through the probability distribution of Chinese character,so it plays much better than other approaches in unknown word recognition.This idea takes a machine-learning method called maximum entropy for implementation and two experiments for comparing and analyzing the results.

Key wordsChinese word segmentation      Character-position      Maximum entropy      Unknown word recognition
