Since the automatic word segmentation of Chinese text will bring the lack of information, method of word segmentation according to lexical chunk as segmentation unit are proposed. Use traditional segmentation method segment Chinese text based calculate mutual information between two lexical entries and adjacent frequency of two or more lexical entries, according to this calculated value judge and sign the lexical chunk by relevant words. The experimentation shows that after the word combination, the lexical chunk bear much more feature information which shares a better effect of the process. It also has proved the effect of feature selection in Chinese text categorization and enhanced the capability of text classification.
