We participate in the subtask technical trend map creation of patent mining task at NTCIR-8. In this paper, we define this task as a knowledge extraction task for patent abstracts and the CRF method and Rule method are introduced in our approach. Compare with the evaluation results, we find out the effect of method of integrating CRF model and Rule model is better than that only using CRF model. However, extraction task of tag is more difficult than tags.
