Embodiment Construction
[0060] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0061] Please refer to figure 1 , the present invention provides a view-level text sentiment classification system based on a graph convolutional neural network, including:
[0062] A text preprocessing module for characterizing view-level text;
[0063] The text semantic information acquisition module is used to capture the bidirectional semantic dependencies of the text;
[0064] Attention encoding module, which is used to capture the global internal correlation of text word sequences and perform further information integration;
[0065] The graph convolutional neural network module applies GCN directly to the sentence dependency tree to model the sentence structure, which can propagate context and dependency information from viewpoint words to viewpoint words;
[0066] The sentiment category output module uses the classification function to obtai...
