【Abstract】 Automatic Chinese word segmentation is the prerequisite for Chinese information processing,and dictionary is the basis of automatic Chinese word segmentation.Whether a dictionary mechanism of word segmentation is good or bad directly affects the speed and efficiency of Chinese word segmentation.In this paper,three kinds of Chinese word segmentation means and five kinds of dictionary mechanisms are introduced in detail.In the end,a simple and effective dictionary mechanism for Chinese word segmentation is proposed.Furthermore,through theoretical analysis and experiment,we compare and illustrate the differences in efficiency of a couple of dictionary mechanisms,and use the conclusion to prove the effectiveness of our dictionary mechanism for word segmentation.更多还原
