汉语名物性短语句法位置语料库的设计
[作者]王家钺;
[摘要]汉语句物性短语 (NP)在汉语信息检索中有重要价值。本文以非统计的信息处理方法为出发点 ,介绍一个汉语名物性短语句法位置语料库的设计思想、所使用的句法位置标记集以及标记加工规范 ,并指出了这样一个语料库的潜在价值。目前正在以此为出发点建立一个汉语名物性短语句法位置语料库。

基于PATRICIA tree的汉语自动分词词典机制
[作者]杨文峰; 陈光英; 李星;
[摘要]分词词典是汉语信息处理系统的一个基本组成部分 ,其查询和更新效率将直接影响汉语信息处理系统的性能。本文采用PATRICIAtree的数据结构 ,设计了一种可以对词典词条进行快速查询、更新的分词词典机制 ,并从理论上初步分析了它的性能。最后通过实验 ,在时间效率上与逐字二分的分词词典机制进行了比较。结果表明 ,基于PATRICIAtree的分词词典机制具有更高的查询速度和更新效率 ,能满足大规模、开放文本处理系统的需求。
[Abstract]The dictionary mechanism is the basic component of Chinese informationprocessing systems,and its efficiency will greatly affect the performances of those systems.Based on the data structure of PATRICIA tree,this paper designed a new PATRICIA tree based dictionary mechanism.Firstly,the paper presents the primary function analysis of this PATRICIA tree based dictionary mechanism.Then a comparison is given between PATRICIA tree based and binary seek by characters dictionary mechanism.All the results p...

Hough变换在中文名片图像倾斜校正中的应用
[作者]潘武模; 焦扬; 王庆人;
[摘要]近来 ,文档图像的计算机自动理解已取得很多进展。但是 ,对于具有倾斜的图像的理解仍然存在许多困难。这种困难在中文名片图像自动识别与理解系统中尤为突出。必须在系统的输入端对图像作有效的倾斜校正以保证系统的性能。由于中文名片版面复杂 ,名片中文字行以及每行字符较少 ,使得现有的倾斜校正算法在处理名片图像时效果很不理想。Hough变换可用于一般文档图像的倾斜校正。但是 ,Hough变换在名片图像中的应用还有待研究。本文提出一种二级Hough变换算法 ,并应用于名片图像理解系统 ,利用名片图像自身的特点提高Hough变换的精确度和速度。这一方法的效果已被实验结果所证实。
[Abstract]Automatic document understanding has undergone great progresses in the past decade.Yet the difficulties due to image skewness have not been overcome.Such difficulties are especially vital in Chinese Business Card understanding systems.Because of the complex card layout,none of current de skew algorithms shows satisfactory performance on Chinese Business Card image.Although Hough transform has been widely used in the de skew of general document image,it's application to Chinese Business Card image needs mo...

用网络[定向图]实现形态素之间的接续提高假名汉字转换的用户操作性能
[作者]中岛晃; 河野胜也;
[摘要]本文描述了把扩展句节数最小法进行形态素解析的结果登录在网络 [定向图 ]上 ,并把这个网络 [定向图 ]保留在计算机的内存中直到修改操作结束 ,实现了在不同句节切分的各种选择候补中取出所需候补。再根据所选候补去检索网络 [定向图 ]上的路径 ,就可以得到符合操作者意图的全句的转换结果 ,从而使日文汉字输入时所需的假名汉字转换操作简单易行 ,提高了操作性能。
[Abstract]Japanese sentences were recently got by transforming‘kana sequence’into the array of the several syllables.We investigated conversion algorithm and user interface, having following characteristics.We got other syllable boundaries without changing action about those. We adopted fundamentally a method of‘minimizing a sum of syllables in a sentence'. In this method, the result of searching dictionary and of grammatical checking about the chain of the morphemes are maintained in the computer′s memory, so we...

现状和设想——试论中文信息处理与现代汉语研究
[作者]许嘉璐;
[摘要]本文介绍了中文信息处理技术发展的现状及面临的主要困难 ,指出 :关键在于对现代汉语研究的滞后。到目前为止 ,中文信息处理主要依赖于对大规模语料的统计 ,根据概率 ,对词与词的关系作出界定。多年来中文信息处理技术徘徊难进的现实说明 ,这一方法已经难以突破“瓶颈” ,要使计算机对现代汉语进行自动化的处理 ,即使之真正“智能化” ,就必须把人的语言知识“教”给计算机。这就需要根据计算机的要求加强对现代汉语的研究 ,特别是对语义的研究。文中介绍了当前朝此方向努力并已有较大进展的三个流派 ,并分别指出其不足 ;参考作者主持国家“九五”重点项目“信息处理用现代汉语词汇研究”的经验 ,提出了统一使用资源、携手并进、共同攻关的设想
[Abstract]The paper surveys the state of the art of Chinese information processing and the major obstacles being faced currently, pointing out that the underlying factor to block the development of Chinese information processing is the lag of the systematic and in depth study on contemporary Chinese language. The main stream in Chinese information processing community depends heavily on corpus based methods, by making full use of the statistical relationship among words, in recent years. The fact that the Chine...

句法范畴的代数结构与演绎系统
[作者]于江生;
[摘要]本文给出了建立在含幺半群基础上的范畴语法的代数结构 ,定义了范畴方程和它的解并对范畴方程的解作了分类 :相容性的相关性。定理“对于范畴方程的任意一个解X ,都存在唯一的本质解Y使得Y X”使得我们可以通过一定的演绎规则对词w的本质范畴作扩张以得到w的所有句法范畴。最后 ,作者从范畴理论的角度给出了句法范畴演绎系统的数学描述
[Abstract]In this article,we showed the algebraic structure of syntactic categories based on monoid and defined categorial equation whose solutions are described by consistency and correlation .The result “If X is a solution of a categorial equation,then there exists an unique essential solution Y such thatYX”makes it possible that the essential catgories of a word could generate all possible syntactic categories by some deductive rules.Finally,the author described the deductive system of syntactic categories from t...

汉字自适应散列分组查找算法
[作者]王忠效; 范植华;
[摘要]在文献 [1]的基础上 ,本文提出了一个适合中文信息处理用的汉字自适应散列分组查找算法。由于引进了动态遗忘机制以及根据频率动态调整汉字顺序 ,算法的平均查找长度成倍缩短 ,从而能够更有效地保证涉及大量汉字信息检索操作的应用对时间性能的要求。此外 ,提出了一个与文献 [1]相比计算量更小、散列效果相当的散列函数
[Abstract]Based on a previous algorithm proposed in [1],this paper addressed an adaptive hashing algorithm of Chinese characters.By introducing an oblivious policy and sorting Chinese characters in accordance with their dynamic frequencies,the algorithm made important improvements on the average search length of Chinese characters,which could better guarantee the strict demand on time of any application driven by the dyanmic statistics of Chinese texts.In addition,a simpler hash function was given which sorked almost...

[Abstract]In this paper we describe a fast high frequency strings extracting algorithm. Our approach uses HASH technology to avoid relying on corpus and word segmentation. To extract the high frequency strings, we only use statistics information. After processing the prefixes and suffixes, the high frequency strings we get can be the supplement knowledge for the un-login words processing, word disambiguation and word weighting. The experimental results show that it has a high speed and can work on arbitrary texts. O...
