Abstract：The paper proposes some methods of definition extraction for concepts in the comprehensive OntoThesaurus. They achieve good experiment effects and are applied to the actual OTCSS. Among them, an integrated algorithm named “two-dimensional relative quantity” based on “high-frequency words vector”and “TF*IDF vector”is presented. This algorithm can much effectively extract good results from that of the first two methods, and the effective information improving ratio can reach 60% generally.
