Embodiment 1
[0052] A text error correction method in the power grid field dispatching scene of the present invention, the process scheme also needs three preliminary preparations, namely named entity recognition model, entity knowledge base, maintenance of pinyin dictionary and text files based on a large number of call records The probability model for training, the probability model can be n-gram or LSTM similar deep learning model, what the present invention adopts is Transformer+Bi-LSTM, the input of this model is a sentence, in a sentence, some specified types will be set, If the entity is of a related type, it is replaced by the object type to be input as a feature word, and the output is the probability of each word.
[0053] After the preparatory work is completed, take "Well, ah, check the Xiazhongshan substation, whether the sister and brother switch on the neutral point arrester on the 1-acre bus is a monk" as an example, see figure 1 As shown, the process of text error correct...
