| Abstract: | This paper proposes a method of domain name recognition based on heuristic rules, to overcome the shortage of traditional solution in specific domain. It firstly studies chemical name in Chinese to obtain its domain features and statistical language features, and then on the basis of such features，it puts forward several heuristic rules, which is applicable to domain name recognition of chemical literature. Comparison experiment shows this method can improve the efficiency of domain name recognition obviously. |
