Abstract: Chinese word segmentation is a base for Chinese Information Processing, and the ambiguity problem is a nodus of Chinese word segmentati on and more then 90% of ambiguity problems are crossing ambiguity, so the solution of the crossing ambiguity problem is an important part of Chinese word segmentation. After repeated experiments and analyses, 5 rules and an algorithm based on these 5 rules were proposed to segment crossing ambiguity. From experiment results, it can be found that the accuracy of DSfenci system we developed based on these 5 rules reaches to 95.22%, which is an excellent experiment result.

Key words: crossing ambiguity, rules, statistics
