汉语自动分词词典机制的实验研究
[作者]孙茂松; 左正平; 黄昌宁;
[摘要]分词词典是汉语自动分词系统的一个基本组成部分。其查询速度直接影响到分词系统的处理速度。本文设计并通过实验考察了三种典型的分词词典机制:整词二分、TRIE 索引树及逐字二分,着重比较了它们的时间、空间效率。实验显示:基于逐字二分的分词词典机制简洁、高效,较好地满足了实用型汉语自动分词系统的需要。
[Abstract]The dictionary mechanism serves as one of the basic components in Chinese word segmentation systems.Its performance influences the segmentation speed significantly.In this paper,we design and implement three typical dictionary mechanisms,i.e.binary seek by word,TRIE indexing tree and binary seek by characters,from word segmentation point of view,and compare their space and time complexity experimentally.It can be seen that the binary seek by characters model is the most appropriate one being capabl...

[摘要]本文在大规模语料基础上提取和分析了中文姓氏和名字用字的使用频率,研究了中文姓名识别的评价函数,动态地建立了姓名识别统计数据表和姓名阈值。提出了在不作分词处理的原始文本中进行中文姓名识别的方法。经开放测试,召回率为95 .23 % ;精确率为87 .31 % 。
[Abstract]This paper dynamically builds parameter table and threshold by extracting and analyzing usage frequency of characters of Chinese names based on large scale corpus and researches evaluation function for Chinese name recognition. And it presents the method of Chinese name recognition without text segmentation. After open test, the recall rate and precision rate are respectively 95.23% and 87.31%.

基于DOP的汉语句法分析技术
[作者]张玥杰; 朱靖波; 张跃; 姚天顺;
[摘要]本文提出一种以DOP技术作为基本框架,同时利用基于相似的概率评估技术,实现汉语句法分析的方法。其中,对于输入语句,首先需要经过词汇层与词性层两层初选。然后,基于已构建知识源,获取输入语句的片段组合形式。最后,对输入语句与初选结果进行相似性评估,完成输入语句的组合分析过程。为论证方法有效性,基于包含1 000 个语句的真实汉语语料构建知识源,并采用包含100 个语句的真实汉语语料作为测试集。实验表明,句法分析的各项指标都比较令人满意,可有效地实现汉语句法分析。
[Abstract]This paper presents a kind of Chinese parsing method which takes the DOP technique as the basic frame and utilizes the similarity based probabilityestimate technique. In the implementation, every input sentence must by preprocessed through the initial selection in word level and part of speech level. Then the fragment combination forms of the input sentence are acquired based on the constructed knowledge source which includes treebank, fragment bank and fragment combination bank. Finally, the similar...

汉语文本动态字母表0阶模型算术编码
[作者]王忠效; 范植华;
[摘要]本文探讨汉语文本的0 阶统计模型的构造方法,提出了一个卓有成效的汉语文本压缩算法。仅仅凭借这一最初级的模型,汉语文本的编码效率已经超过LZ与Huffman 编码的混合算法。由于0 阶统计模型是各种高阶统计模型的基础,所以,本文对汉语以及其他大字符集文种( 如日文、朝鲜文) 的文本压缩研究具有重要的参考意义
[Abstract]This paper addressed the construction of a dynamic alphabet order 0 model of Chinese text for arithmetic coding and provided an algorithm of Chinese text compression.The model had shown to be of high performance because the algorithm driven by it could compress Chinese texts more efficiently than those that combined both LZ and Huffman coding.Because order 0 model laid the foundation of order n models,what the paper discussed was important to the text compression of any large alphabet natural language,...

[作者]江荻; 周季文;
[摘要]为解决藏文排序问题,本文提出藏文的构造序和字符序概念,并在此基础上提出解决藏文词典序的计算机方案。文章对各类藏文构造及字符进行了分析和赋值,给出了藏文计算机排序的技术流程图
[Abstract]On the basis of coded character sets for Tibetan information processing,we need to discuss the sequence of Tibetan words and the method of making sequence. First, we put forward a concept of construction sequence for Tibetan words, which is much different from the sequence of Tibetan transliteration. There are two sequences in Tibetan, one is word order in dictionary, the other is character order in words as well as in a dictionary, and both of them make the structure inconceivable complex with multi hiera...
