The Research On Conversion Of Noun And Its Case From Classic Mongolian Into Cyrillic Mongolian

There are three kinds of written languages are used by Mongols today, such as classic Mongolian,todo Mongolian and Cyrillic Mongolian.Text in the there written languages is reaching the purpose of conversion by artificial method. In the present time of rapid development of science and technology, artificial converting method is no longer adapted to the needs of information age.For this, the paper puts forward the topic of "the research on conversion of noun and its case from classic Mongolian into Cyrillic Mongolian", and puts forward a research idea as follows:①At first, we use the conversion method based on classic Mongolian-cyrillic Mongolian dictionary.②Secondly, we can apply the conversion method of breaking up stem and suffix, that is, break up the stem and suffix of noun, search the stem from stem-library, search the suffix from suffix-library, if we can find out them then use the connection rule to obtain conversion result.③We can use the conversion method of text rule, that is, according to the text feature of classic Mongolian and Cyrillic Mongolian, analyze the corresponding rule of two texts, and use it to convert noun one by one.④If the above three methods are in failure, we use the method of statistical conversion based on corpus finally. We are able to apply N-gram language model to analyze corpus and obtain the probability of word fragment S converted into word fragment T. According to the probability, auto-conversion system gives the conversion result most likely. Then we can reach the purpose of improving conversion accuracy.The research on conversion of noun and its case from classic Mongolian into Cyrillic Mongolian can bring reference value and experimental methods to the research on conversion between classic Mongolian and Cyrillic Mongolian. It can bring actual effectiveness to the science,culture,education and economic development of Mongolian, in addition, it is conducive not only to culture exchange and sharing information between Mongolian and China's minority but also to harmonious coexistence and common development of two countries.
