多次Hash快速分词算法

中文分词是中文信息处理的一个重要的组成部分.一些应用不仅要求有较高的准确率,速度也是至关重要的.通过对已有分词算法的分析,尤其是对快速分词算法的分析,提出了一种新的词典结构,并根据新的词典结构提出新的分词算法.该算法不仅实现对词首字的Hash查找,也实现了词的其它字的Hash查找.理论分析和实验结果表明,该算法在速度上优于现有的其它分词算法.

Multi-hash indexing algorism for Chinese character segmentation

Chinese word segmentation is a very important component and the preparation for Chinese information process. In a lot of application, the precision of word segmentation is paramount, at the same time the velocity is also needed. Through the analysis of the existing algorithms of Chinese word segmentation, especially the fast algorithms, a highly efficient algorithm for Chinese word segmentation is introduced, which is based on the improvement of existing data structure for Chinese dictionary. It not only supports hashing operation on the first Chinese character, but also on the other characters. In theory, the above data structure achieve much more efficiency than other methods,
