| 摘 要： | 分词识别和歧义消除是影响信息检索系统准确度的重要因素，该文提出了一种基于语法和语义的使用约束矩阵的中文分词算法。该算法建立在语法和句法的基础上，从语境角度分析歧义字段，提高分词准确率。系统可以将输入的连续汉字串进行分词处理，输出分割后的汉语词串，并得到一个词典。再用《现代汉语语法信息词典》进行处理，实验结果显示分词准确率能提高10%左右。

| Abstract: | Words segmentation recognition and ambiguity resolving are vital factors for information retrieval precision.This paper presents aChinese word segmentation algorithm with restraint matrix based on the grammar and the semantic.The algorithm improves the accuracy of word segmentation,by combining morphology and syntax with language situation.Continuous character bunch input can be segmented,and then the cut apart word bunch output can be obtained,and one dictionary can be obtained.Then "modern Chinese grammar information dictionary" is used to carry on the processing.Experimental result show the segment accurate rate can enhance about 10%. |
