Abstract:Word query in Chinese Dictionary is essential part in Chinese information processing system. It has a great impact on system efficiency. The Chinese word segmentation has been studied since the late 1980s. In order to improve the existing word query efficiency, for short word of no more than 4 Chinese characters, a new hash algorithm is proposed, named Zipper-style hash indexing based on the value of each characters in Chinese word. The hash value is calculated according to machine code of each character, the weight of the left character is big than the right. The weight is equal to the maximum value of all Chinese characters minus the minimum value. The speed of word query is improved with this kind of Zipper-style Chinese word value hash indexing.
