| 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. |

| Keywords: | Chinese word segmentation search engine first character Hash indexing level-pattern shortest paths paths selection |
