Research on conversion approach between traditional Mongolian and Cyrillic Mongolian

Traditional Mongolian and Cyrillic Mongolian are both Mongolian languages and are widely used in China and Mongolia respectively. With almost the same pronunciations, their written forms are totally different. According to the characteristic of the two languages, this paper proposes a joint sequence model based approach and depicts in detail the corresponding experiments performed. In the experiments, the word error rate and letter error rate for the traditional Mongolian to Cyrillic Mongolian conversion system are 18.38% and 6.75%, and that for Cyrillic Mongolian and traditional Mongolian conversion system are 18.77% and 7.14%. Experimental results show that the proposed approach can meet the basic requirements for practical use.
