A large scale manually annotated Chinese corpus and a number of well-conducted experiments were used to identify the following points of the hidden Markov model based part-of-speech tagging scheme for Chinese texts. The results are:① The Bigram model is better than the Trigram model in terms of the performance-cost ratio.② An annotated corpus of about 70000 words tokens would be sufficient for training the Bigram model, to produce system performance of about 93% tagging accuracy for ambiguous word tokens and 97% tagging accuracy for all word tokens in the texts.③ The Bigram model can be suited to different application domains quite well.
