[Abstract]:The modeling of social network structure is the basis of other fields of social network research, aiming at constructing a reasonable social network structure model. However, for many reasons, such as privacy protection, it is almost impossible to obtain all the data needed to construct the social network structure model, so it is very necessary to study the use of incomplete data to construct the social network structure model. Although there are many existing methods of constructing social network model, there are some problems. For example, the early static model does not have all the topological characteristics of social network. In most dynamic models, nodes grow infinitely with time. In this paper, first of all, from the perspective of application scenario analysis, we refine the technical requirements, and then from three different angles of time, space and space fusion, we design three kinds of social network structure models-natural growth model based on historical events. Reconstruction model based on local network information and spatiotemporal fusion social network model. The natural growth model based on historical events is a dynamic model based on behavior principle and the influence mechanism of event on network structure. The reconstruction model based on local network information is based on two kinds of link prediction indexes: the modified co-neighbor similarity and attribute similarity, while the space-time fusion social network model combines the basic theories of social network natural selection and so on. Based on the Netlogo experimental platform, this paper uses different experimental data and methods to verify the above three network models. Experiments show that the three network models have better accuracy under different conditions. Therefore, according to the difference of available data, the corresponding model can be selected to establish the social network structure in the specific application scenario. In addition, the structure of social network changes with the change of external environment and the state of node itself, but the change of social network always makes the structure of social network more stable as a whole.
