Abstract

In order to improve the accuracy and recall rate of terminology extraction results in the field of new energy vehicles, this paper presented a domain terminology extraction model for the new energy vehicles patent text. Traditional domain terminology extraction methods rely too much on human-defined features and specialized domain knowledge to automatically mine implicit features whose recognition performance greatly depends on the quality of the selected features. In order to solve the problems, this paper proposed a model from the perspective of deep learning. Firstly, it extracted the domain terms by a combination of BLSTM(bidirectional long short-term memory) model based on the attention mechanism and CRF(conditional random fields) model(BLSTM_attention_CRF model), and then it corrected the result by a combination of dictionary and rules. Experimental results show that the accuracy of BLSTM-ATT-CRF model can reach more than 86%, which shows that BLSTM-ATT-CRF model is effective to term extraction of new energy vehicles.
