Research and Application of Data Governance System Based on Natural Language Processing Technology
In natural language processing technology,the long computing time and limited learning ability of chinese word seg-mentation model are the problems perplexing the academic circles.A combined SACNN+CRF model is proposed,it combines the advantages of self attention mechanism,convolution neural network and CRF to complete the task of Chinese word segmen-tation.The best parameter test results show that the best hiding number and the best iteration times of SACNN+CRF model are 100 and 200.Compared with BiSTM+CRF model,MAE,RMSE and MAPE of SACNN+CRF model it increases by 32.98%,41.89%and 36.58%,respectively.The proposed SACNN+CRF model has high efficiency and high value in the ap-plication of chinese word segmentation task.
