Research on Recognition Model and Recognition Effect of Network Public Opinion Visual Emotion under Multi-Dimensional Attention Mechanism
[Objective]To fill the current deficiency in visual emotional analysis research,a ResNet34-based improved emotion analysis model was constructed to analyze and improve the accuracy of image emotion classification.[Methods]Firstly,a visual emotion recognition model was established based on the ResNet34.Then,by integrating the CBAM module and Non-Local module,emotion features were learned and represented.Finally,the above model was used to classify and recognize emotional features,and compared with VGG16 and ResNet50 models.[Results]The recognition effect of the constructed model was verified through experiments,and the research results showed that the accuracy,precision,recall,and F1 score of the model reached 84.42％,84.10％,83.70％,and 83.80％respectively.Compared with the baseline models of the VGG16 and ResNet50,the accuracy of the proposed model was improved by 4.17％and 3.44％,and the F1 score was improved by 4.20％and 3.30％.[Limitations]The scale of the test dataset is relatively small,the effectiveness of annotation was not calculated using metrics such as the Pearson correlation coefficient,and a comparison was not made with visual-based emotion classification algorithms.[Conclusions]From the perspective of visual emotional analysis,optimizing the emotion recognition model supplements the analysis mode of emotional computation,providing support for the extraction and analysis of emotional features in public opinion information.
