Abstract

The application belongs to the technical field of internet application, and particularly relates to a key user discovery method for subfield and wide-area socialization, which comprises the following steps: obtaining user basic information, user historical behavior and user social content under a current topic, and extracting field information and social information from the user basic information, the user historical behavior and the user social content; calculating field recognition degrees of one user to another user according to the field information and the social information, and establishing a topic propagation network by taking the users as nodes and the field recognition degrees as edge weights; in the topic propagation network, obtaining structural features of nodes by walking based on a bias sampling strategy; and establishing a two-layer graph convolutional neural network, which comprises a cascaded first graph convolutional layer, a Dropout layer and a second graph convolutional layer, and inputting the structural features of the nodes into the network to predict whether the nodes have influence; the application can discover key users for specific fields, select key users with more influence for customers to promote products, and improve the effectiveness of advertisement delivery.
