| 摘 要： | 提出了一种基于字特征的中文文本分类方法。该方法的出发点是变常用的基于表层的匹配为基于概念的匹配,用汉字特征向量作为文本的表示方法。算法根据文本中汉字的特征建立文本表示矩阵和类别表示矩阵,并通过线性最小二乘算法形成分类矩阵。

| Abstract: | This paper introduces a method on automatic text categorization based on the statistic features of Chinese characters.The significant character of this method is to make a shift from the surface-based matching to conception-based matching.It takes Chinese features vector as text expression ways.Algorithm should build text expressing matrix and classification expressing matrix according to Chinese character features in text,and build classification matrix through using LLS(Linear Least Square)technique. |

| Keywords: | Chinese character text categorization classification matrix feature vector |
