Embodiment Construction
[0040] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0041] Please refer to figure 1 , the present invention provides a kind of cross-domain emotion classification system based on layered attention mechanism, it is characterized in that, comprises:
[0042] Text preprocessing module, used to characterize cross-domain text;
[0043] In this embodiment, since the input data of the neural network is generally a vector for end-to-end training of the model, it is necessary to perform vectorized representation on the text data. In order to facilitate data processing and analysis, the text preprocessing module in this embodiment first performs word segmentation on the text of the source domain and the target domain and filters stop words; then, the text data is converted from text form to vector by word2vec form.
[0044] The pivot feature extraction module is used to learn the feature representation space ad...
