Abstract: Texts generated by college students through social sharing are characterised by emotional richness and psychological vulnerability. To address the issue that existing social-psycho-emotional profiling methods for college students rely on the size of the labelled dataset and have unsatisfactory classification results, this article first optimises semi-supervised learning (MSASL), which composes the samples and incorporates a smoothness loss while imposing consistency constraints. The BERT model is then used to obtain a semantic representation of the social text, using interactive attention to capture important feature information related to the opinion tendency of the topic words. Finally, semi-supervised GAN (MSASL-GAN) is applied to optimise the text feature representation, and the sentiment feature classification results are output through the fully connected layer. The experimental results show that the classification accuracy of the proposed method is improved by 5.01%-11.51% compared with the comparison model.
