基于词链的自动分词方法

An algorithm for automatic segmentation of Chinese word,which is an improved version of the minimum matching algorithm,is put forward.The key idea of the algorithm is to optimize the word bank and the matching process to enhance the speed and accuracy of word segmentation.By integrating the case bank for processing ambiguous word chain with relevant segmentation rules,the correctness of word segmentation is enhanced,which partly makes up the deficiency in processing natural language.
