Abstract  

This article uses the model of CRF to conduct an experiment for comparing recognition performance and recognition efficiency between the way based on char labeled and the way based on word labeled. The experiment result shows that the performance of based on char is better than that of based on word at the expense of costing more time. In addition, it also pays more attention to the quantity of feature’s influence on the experiment performance.  
Key words： CRF      Chinese chemical substance names      Labeled on char      Labeled on word      Quantity of feature
