Embodiment Construction

[0045] The invention will be described in further detail below in conjunction with the accompanying drawings.

[0046] Explanations of terms involved in the present invention include:

[0047] The so-called structural hole refers to the gap between non-redundant contacts, that is, there is no edge relationship between a pair of neighbor nodes of a node, and the node with more structural holes is more important in the network. The N-Burt algorithm includes the following steps:

[0048]a. From the network neighbor matrix A ij ,according to Calculate the degree value k of each node i ;

[0049] b. According to Q(i)=∑ v∈Γ(i) k i The formula calculates the adjacency Q of each node;

[0050] c. According to Calculate p between each pair of connected nodes ij ;

[0051] d. According to NC i =∑ j∈Γ(i) (p ij +∑ k p ik p kj ) 2 Calculate the resistance NC suffered by each node structure hole.

Abstract

The invention discloses an implementation method for discovering important users of a weighting network. When solving the ability of different users in a network to influence each other, the method introduces second-layer neighbor node topology of a node to define expenses for maintaining an edge relation of the node, and the method comprehensively considers node bridging importance and node centrality, thereby obtaining importance of the node. The method adopts a structure hole theory to measure the importance of the node, fully considers the centrality of the node, introduces the second-layer neighbor topology of the node, and distinguishes importance of bridging points of different properties. The method comprehensively considers bridging and centrality functions of the node, thereby improving accuracy of an algorithm.

Description

technical field [0001] The invention relates to a method for realizing weighted network important user discovery, which belongs to the technical field of network communication. Background technique [0002] An important node is a small number of nodes that can have a great effect on the structure and function of the entire network compared to other nodes in the network. In recent years, scholars have proposed many indexes and algorithms on important node sorting, mainly in the following aspects: 1. The sorting method based on node neighbor nodes, such as in the document BarratA "The Architecture of Complex Weighted Networks" (Proceeding of the National Academy of Sciences, 2004, 101 (11): 3747-3752) proposed weighted degree centrality (weighted degree centrality), that is, the more nodes there are neighbor nodes, the greater its influence, the disadvantage is that only the local information of nodes is considered; :Generalizingdegreeandshortestpaths"(SocialNetworks, 2010, 3...
