计算机辅助汉语教学系统中语音评价体系初探
[作者]郭巧; 陆际联;
[摘要]本文探讨和研究计算机辅助汉语教学系统中语音评价体系的组成与实现方法。采用标准普通话语音示教数据库和非特定人大词汇量标准普通话汉语语料数据库，建立标准普通话示教语句特征模板库。采用Ｋｏｈｏｎｅｎ自组织神经网络进行学习者语音信号的分类与识别，经过汉语语音教学效果评价系统的处理，获得相应的量化评价结果。初步给出了计算机辅助汉语教学系统中语音评价体系的总体框架及其实现方法。通过实验验证了本语音评价体系的设计方案是合理的、可行的。它基本上能够满足计算机辅助汉语教学系统在线评价学生语音学习效果的需要。
[Abstract]To study the frame and methods of the evaluation system for the learner's pronunciations in a computer aided Chinese teaching program. We build up the feature data base of the standard Putonghua teaching program, and use the Kohonen self-organized neural network in the process of pattern recognition. The quantitative evaluation results of the learner's pronunciations can be got after the treatment of the evaluation system. We propose the frame and the methods of the evaluation system for the learner's pron...

粤-普机器翻译中的词处理
[作者]张小衡;
[摘要]粤语和普通话之间的机器翻译研究应首先考虑由粤语到普通话的书面语翻译，并以单词为突破口。本文重点讨论粤－普书面语机器翻译中的词处理，尤其是方言词处理，包括方言词的识别和方言词的翻译两方面，同时介绍一个已经初步实现了的单词级粤－普机器翻译试验系统。文章最后将给出结论和讨论。
[Abstract]Speech-to-speech MT (Machine Translation) between Cantonese and Putonghua is a quite demanding job. It makes sense to deal with Cantonese-to-Putonghua text MT first. The text MT program is an important component of a Cantonese-to-Putonghua speech MT system. In addition it can independently play a helpful role in language communication and serve as a CALL ( Computer-Assisted Language Learning) tool for standard Chinese writing as well. The critical task in Cantonese-to-Putonghua text MT is word processing, e...

一种自组织的汉语词义排歧方法
[作者]李涓子; 黄昌宁; 杨尔弘;
[摘要]长期以来，词义排歧一直被认为是自然语言处理的难题之一。本文用机器可读词典《现代汉语辞海》提供的搭配实例作为多义词的初始搭配知识，采用适当的统计和自组织方法自动扩大搭配集；为保证学习质量，在学习过程中逐渐增大上下文窗口的长度；提出使用搭配统计表的多元最大对数似然比词义排歧算法。最后，对本文提出的方法进行了实验，实验表明这种算法具有较高的正确率。
[Abstract]Word sense disambiguation has been a difficult problem in natural language processing. This paper presents a method of automatically increasing new collocations by the use of the collocations provided by a machine readable dictionary XianDaiHanYuCiHai; In order to assuring the learning quality, the size of context was enlarged gradually; In the procedure of learning and word sense disambiguating, author gives a multi maximal log word sense disambiguation algorithm.

汉语短语结构定界歧义类型分析及分布统计
[作者]詹卫东; 常宝宝; 俞士汶;
[摘要]本文对汉语短语结构的定界歧义做了全面考察，从歧义格式的组成成分，歧义对外造成的影响，模式歧义和实例歧义的对应关系三方面考察了短语结构定界歧义的不同类型，并对汉语短语结构定界歧义的不同类型进行了初步统计。希望能将计算机处理汉语时碰到的短语结构边界歧义问题进一步清晰化，供理论研究者和应用系统开发人员参考。
[Abstract]This paper analyses the ambiguity of determining boundaries of Chinese phrases in automatic parsing by computer. The type of ambiguity can be classified from three different perspectives. As viewed from component of ambiguous structures, ambiguous phrases can be classified into two kinds: one including terminal symbols, the other not including terminal symbols but only non-terminal symbols. As viewed from the influence of ambiguity, ambiguous phrases can also be classified into two k...

基于转换的汉语基本名词短语识别模型
[作者]赵军; 黄昌宁;
[摘要]基本名词短语的识别在自然语言信息处理领域具有重要作用。本文首先从语言学的角度提出了汉语基本名词短语的概念，然后从语言信息处理的角度将用于基本名词短语识别的知识分为两部分，即表示基本名词短语句法组成的基本结构模板（静态知识）与表示基本名词短语出现的上下文环境特征的转换规则（动态知识）。在此基础上设计了一种基于转换的基本名词短语识别模型，该模型可同时结合这两类知识识别基本名词短语。实验结果显示了较高的识别正确率

现代汉语计算语言模型中语言单位的频度—频级关系
[作者]关毅; 王晓龙; 张凯;
[摘要]Ｚｉｐｆ定律是一个反映英文单词词频分布情况的普适性统计规律。我们通过实验发现，在现代汉语的字、词、二元对等等语言单位上，其频度与频级的关系也近似地遵循Ｚｉｐｆ定律，说明了Ｚｉｐｆ定律对于汉语的不同层次的语言单位也是普遍适用的。本文通过实验证实了Ｚｉｐｆ定律所反映的汉语语言单位频度—频级关系，并进而深入讨论了它对于汉语自然语言处理的各项技术，尤其是建立现代汉语基于统计的计算语言模型所具有的重要指导意义
[Abstract]Zipf's law has been widely researched by the linguists and statisticians.The frequency of English words is the most famous example of Zipf's law .In this paper,by means of experiments,we show that Zipf's law is also available in many language structures of Chinese (Chinese character, Chinese word,Chinese word bigram,etc),And Zipf's law has great effect on many technologies of Chinese language processing, especially the construction of Chinese computational language model.
