Embodiment Construction

[0055] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0056] see figure 1 , the overlapping community detection method based on multi-label propagation provided by the present invention comprises the following steps:

[0057] Step A, constructing a social network graph: read network data, and construct a social network graph with users as nodes and user relationships as edges.

[0058] For example, for a microblog network, each microblog user is regarded as a node in the social network, and the relationship of attention and comment among users is regarded as an edge in the social network; for a collaborative network, each author is regarded as a node in the network A node, with the collaborative relationship between two authors who have jointly published articles as an edge in the social network. The adjacency matrix of the social network graph is stored using a sparse matrix data structure.

[0059] Step B, ...

Abstract

The invention belongs to the technical field of network data mining and particularly relates to a detection method for an overlapping community based on multi-label propagation. The detection method comprises the following steps: A, constructing a social network diagram; B, analyzing a network rough core; C, initializing a label set; D, executing label propagation; E, decomposing a discontinuous community. According to the detection method disclosed by the invention, the link density between every two nodes is fully considered; the detection method has higher accuracy and effectiveness; in addition, manual input of data in the label propagation process is avoided.

Description

technical field [0001] The invention belongs to the technical field of network data mining, and in particular relates to an overlapping community detection method based on multi-label propagation. Background technique [0002] Data Mining refers to the process of extracting hidden, unknown, and potentially valuable information or patterns from large amounts of data. Mining the network community structure can discover the hidden organizational structure information, social functions and interesting attributes among community members, such as common hobbies, etc. in the network. By studying the relationships between communities, individuals, and individuals and communities in social networks, a large amount of valuable information can be mined, which can be applied in many fields. [0003] In the past decade, a series of community detection algorithms have emerged. These algorithms can be divided into the following categories: community detection methods based on density, co...
