Computer model-based analysis of user behaviour and emotional disposition on social platforms

In order to be able to accurately identify user behavior and emotional tendency, this paper firstly adopts the neural network structure to build the emotion analysis model, and divides the model into four parts to analyze the text and emotion in social media, and obtains the information of semantics and emotion-related content in social media text.Secondly, from the semantic and emotional symbol content of the text in social media, the public emotional tendency model is built, and the sharing content and behavior of a large number of users in social media are analyzed.Finally, the association rule mining algorithm is used to extract the text and emotional symbols in social media, to improve the accuracy of the user's emotional tendency analysis model, and to be able to accurately derive the user's behavioral habits.In order to verify the analytical effect of the model, the model was tested, and the training speed of the BLSTM model was fast, and the training time was 1.5 hours in the first iteration of the test with a data set of 1 million.The model is more accurate in analyzing the user's positive emotions, with accuracy and precision around 85% and 90% respectively, and the results obtained are more accurate, meet the user's needs, and enhance the user's experience.
