Embodiment Construction

[0058] The preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings. The accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to explain the principle of the present invention, and are not used to limit the scope of the present invention.

[0059] A specific embodiment of the present invention discloses a method for tracing multi-source rumors in social networks based on community division, such as figure 1 As shown, including the following steps:

[0060] Divide the community based on topological potential according to the infection part of a given social network, and obtain multiple communities with overlapping areas. The nodes in each community form a sub-network, and the number and names of nodes in each community are saved;

[0061] According to the number and name of the nodes of each sub-network obtained after the community division, us...

Abstract

The invention relates to a social network multi-source rumor traceability method and system based on community division, which belongs to the technical field of social network analysis and solves the problems of low traceability rate and large error distance in the prior art. First, community division based on topological potential is performed to obtain multiple communities with overlapping areas. The nodes in each community form a sub-network, and the number and names of nodes in each community are saved; then, single-source The rumor source method calculates the possibility of each node in each community as a source node; selects the node with the greatest possibility of being a source node in each community to obtain a multi-source node. Realized the search for infected multi-source nodes in the social network, with high traceability rate and small error distance.

Description

Technical field [0001] The present invention relates to the technical field of social network technology analysis, in particular to a method and system for tracing the source of multi-source rumors in a social network based on community division. Background technique [0002] Traceability is an important research content of social networks, and it has a very important significance and role in finding the source of rumors and inferring the origin of infectious diseases. The tracing methods of multi-source rumors can be roughly divided into two categories: methods based on clustering and methods based on adjacency matrix. The starting point of the clustering-based method is to separate the infected areas of different sources of infection and trace the source within the infected area. In this way, multiple sources are reduced to a single source, which greatly reduces the difficulty of tracing. However, this type of method currently assumes that the infected areas are not mutually ex...
