基于单元合并的汉字切分算法的改进
[作者]周嫔; 马少平; 姜哲;
[摘要]本文介绍了对基于单元合并的汉字切分算法作出的改进。该改进算法对原算法中的核心部分高级合并部分进行了修改，通过在所有的可合并单元中找最佳合并组合，来避免原来的算法在高级合并过程中可能导致的某些合并错误。经过多个实际样本的测试，所作的改进在不降低原算法各种性能的前提下，消除了原算法在某些情况下产生的错误，进一步有效地提高了切分的正确率
[Abstract]This paper introduces the modification of the Chinese character segmentation method based on units amalgamation. This modified method alters the advanced amalgamation part which is the core of the original method. Because the modified method looks for the best amalgamating combination from all the units which can be amalgamated, it can avoid some amalgamation errors which will be caused by the advanced amalgamation in the original method. By many tests on actual samples, the modification does not decline th...

Internet中文个人信息搜索
[作者]沈达阳; 孙茂松;
[摘要]本文构造了一个用于自动生成Ｉｎｔｅｒｎｅｔ个人信息索引的实验系统ＰｅｒｓｏｎＩｎｄｅｘｅｒ。在ＣＥＲＮＥＴ两个网址上进行的初步实验表明，ＰｅｒｓｏｎＩｎｄｅｘｅｒ对中文姓名、拼音人名、中文机构名的召回率和精确率平均分别为９７．８％和６１．９％、１００％和６４．５％、９４．５％和９２．１％，对电子邮件地址和电话传真号码的召回率和精确率均为１００％。鉴于Ｉｎｔｅｒｎｅｔ上的信息检索以及自然语言处理这两个领域都互向对方提出了要求，我们相信，面向大规模真实文本的汉语分析技术与Ｉｎｔｅｒｎｅｔ的结合，将是今后几年中文信息处理一个新的研究热点
[Abstract]PersonIndexer, a prototype system for automatically generating Chinese personal information index in Internet, is proposed in this paper. Preliminary experimental results on all HTML texts under two CERNET web sites indicate that, the average recall and precision for extraction of Chinese names, Chinese names in Pinyin form as well as Chinese organization names are 97.8% & 61.9%, 100% & 64.5%,94.5% & 92.1% respectively, and the recall and precision for extracting email addresses, telephone and fax numbers ...

曲线轮廓汉字自动生成及其变形方法
[作者]马小虎; 刘玉龙; 潘志庚; 石教英;
[摘要]本文介绍一种基于曲线轮廓汉字和Ｆｏｕｒｉｅｒ级数描述的汉字变形新方法。该方法利用曲线轮廓所提供的字形笔划结构特征信息，运用多级数学模型，通过计算机软件功能，对字形自动进行变形，生成一系列形式多样的新字形，是一种动态汉字库技术
[Abstract]A new method is presented to automatically transform Chinese character based on outline font and Fourier series description. Making full use of structure features of strokes of Chinese character provided by outline font and applying several mathematical models,the method can automatically create various new font,This is a new kind of dynamic font technique.

基于语义知识的汉语句法结构排歧
[作者]苑春法; 黄锦辉; 李文捷;
[摘要]汉语在词类这个语言层次上存在着许多歧义结构，这给汉语的自动句法分析带来了难以逾越的障碍。通过寻找汉语语义类之间可能存在的句法关系建立汉语语义关联网，这为用汉语语义知识来解决句法歧义开辟了道路。文章针对具体的汉语歧义结构研究具体的解决办法，从而减少了计算的复杂度。
[Abstract]There are too many syntactic ambiguities in the Chinese, and it is not easy to parse the Chinese sentences automatically only with the Part of Speech (POS) tagging. In order to overcome this barrier we looked for the possible syntactic relations between the semantic clas ses, then built a Chinese Semantic Associate Net (CSAN). Using the CSAN we find a way to solve the problem about the syntactic ambiguities. In this way we do not try to solve all the ambiguities, we only try to solve the certain kind of am...

中文文本的关键词自动抽取和模糊分类
[作者]何新贵; 彭甫阳;
[摘要]本文提出了中文文本分类的两种模糊方法，一种基于模糊集间的语义距离［２］，一种基于本文中提出的‘模糊分类网络’。两者都必须首先从文本中抽取关键词集合，本文给出了一种主要采用统计方法结合受限自然语言理解技术的模糊关键词集合提取方法，它与模糊分类方法结合，可望达到文本信息的自动分类。所提出的方法同样适合于模式识别之类问题的解决。
[Abstract]Two methods for text classification based on fuzzy techniques are presented in the paper.A concept of ‘fuzzy classification network’is used in the text classification.To meet the needs of these two classification methods,an approach based on statistics and natural language understanding for automatically extracting the Key words from the text is presented.It is point out that the methods are also suitable for pattern recognition and text retrieval.

藏文内码扩展体系
[作者]于洪志;
[摘要]针对藏文编码字符集的基本集和辅助集建立在不同平面、编码体系不同所存在的问题，本文提出建立藏文内码扩展体系，给出了藏文合成、生成、分解的规则和方法：通过内码转换表合成藏文藏文内字，实现基本集与辅助集的信息交换；通过构件集，生成规范、标准的藏文外字，满足藏文编码字符集开放性的需要。并且，向上，在字汇一级，兼容ＵＣＳ；向下，与ＧＢ２３１２的事实上的内码标准兼容，是一个全藏文编码体系。作者建议在ＵＣＳ基本平面的拼音文字区建立内码扩充体系。
