Embodiment 1

[0058] Such as figure 1 As shown, the method for detecting the number of communities in the microblog network provided by the embodiment of the present invention includes:

[0059] S101, constructing a microblog user network model according to the following relationship among microblog users;

[0060] S102. For each user node in the microblog user network model, determine its degree of cohesion and degree of separation, and determine a standard score of the centrality of each user node according to the obtained degree of cohesion and degree of separation;

[0061] S103, according to the obtained standard score of centrality, filter the user nodes in the microblog user network model, and generate a set of candidate community central nodes;

[0062] S104. Select user nodes whose cohesion and separation satisfy a preset relationship from the set of candidate community center nodes as community center nodes, and determine the number of communities.

[0063] The community number ...

Abstract

The invention provides a method and a system for detecting the number of communities in a microblog network, which can quickly and accurately determine the number of communities in the microblog network and a community center node. The method comprises the following steps: constructing a microblog user network model according to an attention relationship among microblog users; for each user node in the microblog user network model, determining the cohesion degree and separation degree of the user node, and determining the standard score of the centrality of each user node according to the obtained cohesion degree and separation degree; screening user nodes in the microblog user network model according to the obtained standard score of the centrality to generate a candidate community centernode set; and selecting the user nodes of which the cohesion degree and the separation degree meet a preset relationship from the candidate community center node set as community center nodes, and determining the number of communities. The invention relates to the technical field of social networks.
