一个拼音汉字自动转换系统的设计与实现

给出了拼音汉字转换的定义，并建立了一个带调拼音词句到汉字语句的自动转换系统。它由五个部分组成，自动分词模块，词法分析模块，句法和语义分析模块，语义修饰模块和显示模块。其中句法分析是系统的核心，在比较各种方法的基础上选择了扩充转移网络模型，使ＡＴＮ的优点和音字转换的特点得到较好的结合，测试结果表明，系统的正确转换率达到９７％。

DESIGN AND IMPLEMENTATION OF A PINYIN CHINESE WORD CONVERSION SYSTEM

The recognition of homonyms is the main problem in Pinyin to Chinese word conversion. In this paper we discuss the definition of Pinyin to Chinese word conversion, and describe the construction of a system which can convert Pinyin sentences with tones into Chinese character sentences. The system is composed of five parts:auto split module, morphology analysis module, syntax analysis module, semantic analysis module and display module. Syntax analysis is the most important part in the conversion and the Augmented Transition Network(ATN) method is chosen in this module. It has been proved that the ATN method is suitable for Pinyin to Chinese word conversion. The test results show that the system achieves a correct conversion rate of 97%.
