Embodiment Construction
[0046] The present embodiment comprises a kind of picture-reading writing type composition automatic scoring method, with reference to figure 1 , the method includes the following steps:
[0047] S1. Use the first convolutional neural network to obtain the n-gram feature corresponding to the sentence of the composition text;
[0048] S2. Using the attention mechanism model to obtain the implicit representation of the sentence corresponding to the composition text according to the n-gram feature;
[0049] S3. Obtain the hidden layer output matrix corresponding to the composition text by using the long-short-term memory network;
[0050] S4. Use the second convolutional neural network to obtain the feature vector matrix corresponding to the picture;
[0051] S5. Calculate the similarity matrix corresponding to the hidden layer output matrix and the feature vector matrix;
[0052] S6. Perform a first attention operation and a second attention operation; the first attention ope...
