The prefix and suffix query of Chinese word segmentation algorithm for maximum matching

Chinese word segmentation is a key technology for automatic summarization. Whether the segmentation is successful and has no ambiguity or not will directly affect sentence weight calculation. In the segmentation process, the structure of word segmentation dictionary is particularly important. A rational structure of a word segmentation dictionary can improve the segmentation process of the dictionary query speed, and, thus, improves the efficiency of Chinese word segmentation. This paper is based on the dictionary of Hash structure. In this paper, the authors adopt the prefix and suffix query approach to build word segmentation dictionary, combined with an improved Chinese word segmentation algorithm for maximum matching to improve the segmentation efficiency and accuracy.
