Embodiment Construction

[0052] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0053] The present invention proposes a method for identifying social circles in an ego network. Firstly, a user's ego network is constructed, and then the similarity of user relationships is modeled by combining structure and attribute information. Then, a clustering algorithm is used to cluster the initialized social circles, and finally extract The characteristics of the social circle are used to classify it, and the identification of the social circle is realized, which specifically includes the following steps:

[0054] 1) Construct the user's ego network: the user is abstracted into a node in the ego network, and the relationship between users is abstracted into an edge in the ego network;

[0055] The ego network is defined as follows:

[0056] In the ego network, nodes are composed of a central node (ego) and neighbor nodes (alters) of this node, and edges i...

Abstract

A method for identifying social circles in the ego network, which abstracts users into a node in the ego network, and abstracts the relationship between users into an edge in the ego network to construct an ego network; combines ego network structure information and node attribute information to model The similarity between edges; initialize each edge as a social circle, and then use the average-linkage hierarchical clustering method to cluster according to the similarity between social circles, and obtain the dendrogram corresponding to the hierarchical clustering algorithm; select the appropriate threshold to intercept the dendrogram to obtain the corresponding edge social circle, and convert the edge social circle into a node social circle; extract the attribute features and structural features of the social circle, and then train a classifier to identify the type of social circle, using this method Identifying social circles is simple and accurate.

Description

technical field [0001] The invention belongs to the field of community division, and relates to an ego network social circle identification method. Background technique [0002] Social circle recognition can help users group their friends into social circles, which can effectively manage the acquired information, and has important applications in link prediction, friend recommendation and other fields. Classical social circle identification methods mainly use two types of information: network structure information and user attribute information. The existing methods can be divided into two categories: node-based methods and edge-based methods. The node-based method divides the nodes in the ego network into different circles, while the edge-based method divides the edges in the ego network into different circles.
