1、 I I 摘要 I 摘要 中文信息处理技术是我国信息产业最重要的技术支柱之一，它是利用计算 机对汉语信息进行自动处理。当前对于汉字的输入已经推出了很多种方法，例 如：手写笔、语音输入等，但汉字的键盘输入还是汉字录入计算机最普及的手 段，它是中文信息处理的一个重要课题。随着智能处理技术在计算机领域的应 用， 汉字的输入法也得到了新的发展， 本文在汉语拼音输入基本框架的基础上， 引入中文自动分词技术，建立了二元统计语言模型，提出了无编码候选词汉语 拼音输入法的实现方法。所谓的无编码候选词输入是指在候选词列表的生成过 程中，根据当前已输入的词组，在不需要输入外码的前提下，智能地将当前可 能会出现的候
2、选词生成候选词列表，供用户选择，并且只要用户输入的目标词 在无编码候选词列表中，这种候选词的生成方式就会一直持续下去。 文章主要包括以下内容： (1) 介绍本文的研究背景以及当前汉语拼音输入法所面临的问题， 简单 阐述了本文无编码候选词输入法的生成原理。 (2) 针对本文采用的汉语拼音输入，对拼音流进行了预处理，实现了从 拼音流到独立音节的切分。 对样本语料库采用了自动机械分词的方 式，并且对分词过程中出现的交集性歧义进行了消歧。根据分词的 结果建立了二元统计语言模型以及对其进行了优化。 (3) 建立了有编码候选词的数据结构，给出了具体生成算法。在上述准 备工作的基础上， 对无编码候选词输入法

4、型 Abstract III Abstract Chinese information processing is one of the most important pillars in our countrys information industry, which utilizes computer to automatically process Chinese information. At present, there are already several methods for the input of Chinese characters, such as: touch pe
5、n, phonetic input and so on. However, the most popular device is to use keyboard, which is an important subject in Chinese information processing. With the application of intellectual processing technology in computer, the method of Chinese characters input has also been greatly improved. Basing on
6、the basic framework of Chinese pinyin input, this paper introduces the technology of automatic segmentation of Chinese characters and bi-gram statistical language model, putting forward the realization of Chinese pinyin input with non-coding candidate words. The so-called non-coding candidate words
7、input means that in the process of generating candidate word lists, basing on the currently inputted words, the computer can intelligently generate candidate words lists of those possible occurring candidates with no outer code and if the target word which the user input is within the non-coding can
8、didate words lists, the generation of this kind of candidate words generation will continue. This paper mainly includes the following parts: In the first part, the author introduces the background and problem in the present research, and briefly describes the basic principles for the realization of
9、Chinese character input. In the second part, the author pre treats pinyin string which is used in this paper and realizes the segmentation of pinyin string into independent syllables. In addition, the author uses mechanical means to segment sample corpus automatically; disambiguates the intersection
10、 of words which occurred during the process of segmentation. Based on the result of segmentation, the author establishes a bi-gram statistical language model, including the optimization of it. In the third part, the author establishes a data structure with coding candidate 无编码候选词汉语拼音输入法的实现 IV words,
11、 and presents the specific generation algorithm. Based on the above preparation work, the author verifies the realization of Chinese pinyin input with non-coding candidate words both in theory and in algorithm. In the fourth part, in order to enable the input system to learn from itself, the author
12、optimizes the big ram statistical language model again based on users input, especially readjusts the word frequency and users editing of dictionary. In the last part, the author realizes the Chinese pinyin input with non-coding candidate words through IMM-IME which is offered by Windows operation s
13、ystem. In addition the author elaborates the formation of Chinese pinyin input with no candidate coding words basing on the IMM-IME and other important design concepts. Finally the author uses the popular VC+.NET to program, especially rewrites the API function which is offered by Windows operation system.
