In this thesis, I summarize and implement the up-to-date language models, such as N-Gram Language Model, Interpolation N-gram Language Model, Context-Free Grammar and Probabilistic Context-Free Grammar, and establish the run-length language model Character-level and word-level run-length language model are established on the base of the concept of limit entropy and discrete stable information source and by using maximum likelihood between character strings.

在充分研究和比较了中文和西文特点的基础上，提出了变长汉语语言模型。应用极限熵、离散平稳信源和字符串之间的最大似然度等概念和方法，建立了字一级的变长语言模型和词一级的变长语言模型。实验的结果显示这种语言模型不仅比Bigram具有更低的复杂度，而且包含了更长距离内的信息，运行时间也大大小于N-Gram。
