The application discloses a hot event controversial analysis method based on a heterogeneous symbolic attribute network, and relates to the technical field of data analysis.The analysis method comprises the following steps: obtaining an original data set from a social network, wherein the original data set contains attribute information; performing a data preprocessing operation, performing text summary processing on all comments of micro blogs, discovering event topics through a topic model, and completing construction of a heterogeneous graph; fusing the attribute information with text information and structure information; performing sentiment analysis according to comment information of users, constructing a symbolic network between users, and completing self-supervised training of the users under the heterogeneous network and the symbolic network; and measuring community controversy according to community differences, intermediary centrality and user propagation representation.The application predicts controversy from different angles based on community discovery results, and analyzes hot events through development of an online service platform, thereby providing convenience for users.

This invention relates to a big data processing method and system for integrating online public opinion into website construction, belonging to the field of data processing technology. It includes the following steps: Step S1: Constructing a multi-source heterogeneous public opinion dataset; Step S2: Performing semantic analysis and entity recognition on the multi-source heterogeneous public opinion dataset, generating a public opinion-user association matrix based on public opinion themes and user profile features; Step S3: Utilizing complex network analysis algorithms to perform community discovery and core node identification on the public opinion-user association matrix, and generating a public opinion development trend prediction curve by combining it with a public opinion heat prediction model; Step S4: Based on the public opinion development trend prediction curve and key user groups, dynamically adjusting the page content display priority through the website content management module, while simultaneously calling intelligent interactive components to generate targeted public opinion response content; The beneficial effects of this invention are: It achieves the integration of public opinion data and website construction data through community discovery and core node identification.

This application provides a user behavior-driven personalized investor education method, apparatus, device, and medium. The method constructs a heterogeneous graph that reflects complex relationships based on user behavior data, and trains a preset multi-layer GAT network using a self-supervised training strategy that combines graph attention network with contrastive learning and soft modularity loss. The output nodes have high-dimensional features that can distinguish individual characteristics and reflect community structure. Based on these high-dimensional features, accurate community discovery can be achieved, and appropriate investor education content can be pushed to different communities.
