A neural network includes: a convolutional network; a multi-feature-layer merging network configured to merge feature maps output by a high-order convolutional layer and a low-order convolutional layer; a spatial regularization network configured to receive the merged feature map; a first content label full connection layer configured to receive a feature map and output a first prediction probability of a content label; a second content label full connection layer configured to receive an N-th order feature map and output a second prediction probability of the content label, the first prediction probability and the second prediction probability of the content label are summed and averaged to obtain a prediction probability; a theme label full connection layer configured to receive the N-th order feature map and output a prediction probability; and a category label full connection layer configured to output a prediction probability of a category label, where 1<n≤N.
