Domain Term Extraction has an important significance in natural language processing, and it is widely applied in information retrieval, information extraction, data mining, machine translation and other information processing fields. In this paper, an automatic domain term extraction method is proposed based on condition random fields. We treat domain terms extraction as a sequence labeling problem, and terms' distribution characteristics as features of the CRF model. Then we used the CRF tool to train a template for the term extraction. Experimental results showed that the method is simple, with common domains, and good results were achieved. In the open test, the precision rate achieved was 79.63 %, recall rate was 73.54%, and F-measure was 76.46%.
