This paper reviewed existing smoothing methods for N-gram model firstly,and implemented the Absolute,W-B and Katz smoothing algorithms respectively.
试验结果表明:新的Katz平滑算法降低了N-gram模型的交叉熵,在汉语分词中应用改进的平滑算法也提高了分词结果的F量度。
We re-examine three classifiers: Bayes based on N-gram model classifier(NGBayes),Naive Bayes classifier(NBayes) and k-Nearest Neighbor classifier(kNN),which almost have the same performance in traditional text classification field.
本文是在噪音环境下文本分类方法的一种探索:把在传统文本分类中性能基本相当的基于N-gram模型的贝叶斯(NGBayes)、基于分词的朴素贝叶斯(NBayes)和基于分词的k近邻(kNN)分类方法应用到网页分类领域,在中文Web信息检索论坛提供的中文网页分类训练集——CCT2002-v1。
This paper presents a new method for segmenting the input Chinese language text sentence into words, which consists of a character-based N-gram model and an efficient Viterbi search algorithm.
该文提出了一种将汉语文本句子切分成词的新方法,这种方法以N-gram模型为基础,并结合有效的Viterbi搜索算法来实现汉语句子的切词。
