Deep Learning Based Knowledge Extraction Method for Text of Power Grid Dispatch and Control
The development of power systems has put forward new requirements for the use of power system knowledge. In order to achieve automatic extraction of unstructured text knowledge of power grid dispatch and control
the deep learning model of attention based bidirectional long- and short-term memory networks and conditional random fields is proposed in this paper. The deep learning model extracts grid operation rules and grid accident processing procedures from text data such as dispatching protocols. The experimental results show that the accuracy
recall rate
and F1 score of the proposed model on the corpus are 91.00%
89.98%
and 90.49%
respectively
and the results are slightly better than the other three models. F1 evaluation is performed on the training set and test set
respectively
and the difference in recognition accuracy is small. This shows that no over-fitting occurs during model learning
and the proposed deep learning model has good generalization ability.
