Abstract: This article based on the research of current technology of Chinese word segmentation,proposes a Chinese word segmentation system to the chemical field,first introduces the dictionary mechanism combined first character hash indexing with binary search,then introduces an improved algorithm based on level-pattern shortest path method with the complementarity of the paths selection mechanism,at last,by analyzing the experiment’s result,this system shows a desired effectiveness as well as eliminating the ambiguity to some extent.

摘要: 在对现有中文分词技术研究的基础上,提出了一种应用于化工专业领域的中文分词系统,先后介绍了首字哈希结合二分查找的词典机制,以及结合路径选择机制而改进了的层进式最短路径切词算法,并经过实验分析,在保证切分效率的同时,在一定程度上达到了消除歧义的效果。
