Abstract

The invention discloses an initial user selection method for competition influence propagation in a social network with attributes. The method comprises the following steps: constructing an undirected graph of the social network with attributes according to the data in the social network, constructing a kernel-attribute-tree according to the undirected graph of the social network, for a commodity A of a needed initial user, under the condition that an initial user set IB of a competitive commodity B in the social network is known, obtaining a candidate user set CSA of the commodity A, calculating marginal influence propagation values after each candidate user is used as the initial user based on a competitive influence propagation model, selecting the current candidate user with the maximum marginal influence propagation value as the initial user, and so on until the number of the selected initial users meets the requirement. According to the invention, initial user selection of commodities can be realized more effectively in a competitive propagation environment.

Description

technical field [0001] The invention belongs to the technical field of social network, and more specifically relates to an initial user selection method for competition influence propagation in a social network with attributes. Background technique [0002] In the real world, the interconnection between individuals constitutes a social network. At the same time, individuals in the social network have their interests, which are reflected in the attributes of users in the social network. Such a social network is called a social network with attributes. The internet. How to select users in the social network with attributes to maximize the influence of competition is an important aspect of social network research. A social network with attributes can be described as an undirected graph G=(V,E,P,W), where V={v 1 ,v 2 ,...,v N} represents the set of individual nodes, v i Represents the i-th individual node, i=1,2,...,N, N represents the number of individuals, E={e 1 ,e 2 ,...
