智能拼音-汉字转换系统实现研究

IMPLEMENTATION OF AN INTELLIGENT PINYIN-HANZI CONVERSION SYSTEM

本拼音 -汉字智能转换系统的主要特征 ,是利用扩充的LR句法分析和基于二元语义的类属语义分析方法消除同音词的歧义干扰 ,提高转换的正确率 针对汉语语法特征 ,阐述了汉语语法分析中的两种回溯 ,并扩展了传统LR分析方法 ,提高了语法分析的完备性 为有效地实施语义分析 ,探讨了所使用的类属及类属关系 ,它以一种简单而有效的方式建立、维护和使用句法和语义知识 随着句法和语义知识的不断丰富完善 。

The peculiarities of this system are the use of an extended LR syntactic and the word category semantic analysis based on the Binary Semantic Relations to solve the ambiguity of homophones in the Pinyin Chinese transformation. In terms of the characteristics of Chinese language, an extended traditional LR analysis algorithm in syntax analysis and two kinds of retrospection is discussed, which ensures both the accuracy and the completeness of the syntactic analysis. Then the word categories and their relations are discussed and a framework of the semantic libraries is constructed , which can express the semantic knowledge in a simple and effective way. With the help of the maintenance mechanisms and the continuous accumulation of the semantic knowledge , the system will be able to improve the performance remarkable in the transformation.
