Abstract This paper first studies rule-based method and the statistic-based method of named entity,analyzes the strengths and weaknesses of the two methods.Then it presents a cascaded model for named entity recognition, which combines of the rule-based method and the statistic-based method.In the named entity recoginzation experiment for field of defense,the F value is more than 89%.
