Abstract:

In order to raise the rate of Chinese text retrieval of Chinese fulltext retrieval system on the basis of the Chinese ambiguity inclusiveness and length restrictions, a kind of improved Chinese word segmentation algorithm is proposed based on the existing Chinese word segmentation algorithms. In this improved algorithm the process of indexing establishment makes a mapping from related words to the thesaurus. Through the improvement to the thesaurus, a better mapping is realized. Experiments show that the improved algorithm is a more efficient Chinese text retrieval segmentation algorithm.

Key words: Chinese full-text retrieval, Chinese segmentation, character-based indexing
