  average code length
The average code length c is defined by c=\sumi=1n pi li .
      
In the first and second method the average code length found after application of the Huffmann encoding has been found to be about 4 bits sample-1.
      
Moreover, this best code can be modified to ensure that the almost sure version of the code length has asymptotically the same behavior as its expected value, i.e., the average code length.
      
Secondly, we deal with the problem: what is the "best" achievable average code length with underlying density functionf? Minimax lower bounds are derived for the average code length over certain smooth classes of underlying densitiesf.
      
Without encryption, the average code length for encoding DCs is 5.78 bits.

Serial numbers are given to 3129 different Chinese characters according to their frequency of occurrence in chinese scientific publications amounting to 1 million characters. The result is, with small serial number n, the frequency of occurrence is approximately Zipf distribution, while with big n the distribution approaches exponential. The frist order entropy and the average code length of the optimum code of the Chinese characters are evaluated. The multiple order entropy and the phonetic entropy...

Serial numbers are given to 3129 different Chinese characters according to their frequency of occurrence in chinese scientific publications amounting to 1 million characters. The result is, with small serial number n, the frequency of occurrence is approximately Zipf distribution, while with big n the distribution approaches exponential. The frist order entropy and the average code length of the optimum code of the Chinese characters are evaluated. The multiple order entropy and the phonetic entropy of the chinese characters are also evaluated, and an input scheme is analyzed.

本文根据100万字的科技资料中出现3129个不同汉字的字频统计数据,将汉字按字频大小排序,得出字序n较小时,字频近似于Zipt分布,大n时趋于指数分布的规律。根据这种分布,得到汉字的一维熵和汉字最佳编码的平均码长。又根据汉语拼音统计数据,估计汉字多维熵以及汉语拼音熵,并据以分析汉语拼音输入方案。

作为输入编码的后处理 ,各种类型输入软件智能化的共同目标是由软件来识别和选定上屏的重码字、词与缩短平均码长 ,并促使编码简单化和规范化。本文简要地论述了基于理解的智能输入、基于语用统计的智能输入、基于模板匹配的智能输入和基于上下文关联的智能输入等四种类型的汉字键盘输入智能处理软件的原理、优点和有待解决的问题 ,并列举了每种类型的典型作品。

In Chinese character input, the form-based co di ng method is an indispensable complement to the Pinyin-based method. The former is preferable in the cases where high-speed input is needed, where a large cha racter set is required, where words of single characters or words missing in nor mal dictionaries are abundant, and where unfamiliar or rarely-used characters a re more frequently used.The present paper introduces ZYQ, a stroke-group-based Chinese character input method whose development has been kept...

In Chinese character input, the form-based co di ng method is an indispensable complement to the Pinyin-based method. The former is preferable in the cases where high-speed input is needed, where a large cha racter set is required, where words of single characters or words missing in nor mal dictionaries are abundant, and where unfamiliar or rarely-used characters a re more frequently used.The present paper introduces ZYQ, a stroke-group-based Chinese character input method whose development has been kept under the guidan ce of being Correct (in respect to the norms of language education and language application), Easy (in respect to user friendliness and convenience) and Complet e (in respect to the Chinese character set available). ZYQ has a key-selection rate of 16.4%, while the maximum and average code lengths are 5 and 4.315 respec tively.

“正易全”是一个以“正”、“易”和“全”为基本指导思想的笔组型汉字编码输入法。在“正”方面 ,采用国际标准汉字集ISO10 646CJK ,并以《GB130 0 0 1字符集汉字字序 (笔画序 )规范》和《信息处理用GB130 0 0 1字符集汉字部件规范》指导编码 ;在“易”方面 ,以单双笔笔组和十来个常用部件为码元 ,按笔顺和音托等简单原则映射到 2 6个英文字母建元上 ,从而避免了传统的繁复字根 -键元对应表 ;在“全”方面 ,支持CJK中的所有 2 0 90 2字符 ,包括简体字、繁体字、日韩字和偏旁部首等 ,而且可以在不改变编码方案的前提下进一步扩充字集。正易全的单字最大码长为 5个字母 ,平均码长 4 315 ,键选率 16 4 %。该输入法的笔组 -键元设计和取码模式是在对整个CJK字集作了全字编码以后多次试验、统计和优化后确定下来的。
