| Abstract: | Focusing on the Chinese word rough segmentation, this paper designs a dictionary structure based on Multiple Hash to improve the efficiency of dictionary matching, and meanwhile improve the K-shortest path searching mechanism applied in ICTCLAS based on Deletion Algorithm. Finally, the paper constructs the Chinese word rough segmentation system by the use of the proposed technological schemes. The experimental results prove the good performance of the Chinese word rough segmentation proposed by this paper t... |
