To provide a method and a device for improving element recognition.SOLUTION: A method includes the steps of: acquiring a statement; acquiring a word sequence from the statement; and inputting the word sequence to a previously trained multitask element recognition model on the basis of sequence tagging and entity word prediction, and outputting the entity word, an entity category and an entity word position. The multitask element recognition model includes sequence tagging network and entity word prediction network. The sequence tagging network is used for executing a sequence tagging task, the entity word prediction network is used for executing the entity word prediction, and after a hidden layer of LSTM, BILSTM-CRF network is fused to the entity word prediction network by a fusion model.SELECTED DRAWING: Figure 2
