汉字认知心理研究对机器自动识别汉字的启示
[作者]韩布新; 陈一凡;
[摘要]几项认知心理学实验研究从不同角度一致证实,方决汉字的四个等分象限所含的字形特征信息量不同,在人类识别汉宇时作用也不一样,其中以左上象限最重要,右下象限的作用则要弱得多,本文结合部件的象限位置频率,讨论了这些结果对汉字机器识别的一些启示。
[Abstract]With introduction of the results of several experiments about the effects of the spacial position of Chinese character in the visual recognition of the character, which indicated that the left upper quadrant in the square of Chinese charater in most important while the right lower quadrant, it was discussed that the effects of the constituents positional frequency and their implication to the computer recognition of Chinese characters.

手写印刷体汉字的笔段抽取及偏旁识别
[作者]胡家忠;
[摘要]本文采用对汉字点阵图象进行方向变换的方法抽取汉字的笔段,采用结构分析的方法识别分布于汉字四周的偏旁,对国标一级汉字申的90类偏旁计一万余字进行了偏旁抽取试验,当侯选偏旁数<5时,累计正确侯补率>96％。
[Abstract]In the paper, a method for stroke extraction of Chinese characters is presented by means of direction transformation of dot matrix of Chinese characters. With structure analysis, the peripheral ridcals are effectively recognized. For 99 different radicals in national standard level 1 Chinese characters, an experiment shows that the correct recognition rate is greater than 96% when candidate number amounts to three.

中文文本压缩的自适应算法
[作者]贺前华; 徐秉铮; 彭磊;
[摘要]本文初步分析了中文文本的存储结构特征,并将其应用于文本压缩,对LZW(Lemple Ziv Welch)算法进行了两方面的改进:1、采用变码长编码,对短文本的压缩有显著的效果;2、建立—删除规则,当码本加满以后对码本进行删除整理,使编码过程一直能够积累输入文本的相关信息,对较长文本,其压缩效果比基本LZM算法有显著改善。
[Abstract]This paper discusses the storage_charateristics of Chinese text, and uses them incompessing Chinese text. Improvements of LZW (Lemple_Ziv_Welch) algorithm aremade: (1).Using variable_length coding instead of fixed length coding, which contributesmuch to the compresive rate of short text; (2). A set of deleting rule is proposed, the code table will be adjusted when it gets full, so the algorithm could accomulate the relativity of the input text all the time, which contributes much to long text than the basic...
