Multi-source social network construction method based on user identity association

Abstract

The invention discloses a multi-source social network construction method based on user identity association, and belongs to the technical field of social network analysis. Firstly, the concept of a pseudo hyperedge is defined, and a pseudo hyperedge hypergraph model is constructed; the topological structure similarity between nodes in the hypergraph is measured by introducing a topological intimacy value; and then vectorizing user name attributes of nodes in the hypergraph to perform similarity calculation, further proposing a user identity association method based on a joint locking strategyto realize cross-social-network user matching, and finally performing social relationship filling based on a user matching result to complete multi-source social network construction. According to the construction method of the multi-source social network based on user identity association, network topology information is utilized to the maximum extent, structural characteristics and user attributes are comprehensively utilized for user matching, limitation of a single network is overcome, the constructed network is more complete and accurate, and a good effect can be obtained under the condition that seed nodes are limited.

Description

technical field [0001] The invention relates to a multi-source social network construction method based on user identity association, and belongs to the technical field of social network analysis. Background technique [0002] With the rapid development of Internet technology and the popularization of mobile smart terminals, people exchange information and communicate emotions through multiple social network platforms. Social networks have become an important medium and platform for maintaining social relations and information dissemination. Public opinion monitoring, advertising push and friend recommendation have become one of the frontier hot research fields. The construction of social network is the basis and core of social network analysis research, and the construction of a more complete and accurate multi-source social network is the key to ensure the accuracy and effective application of analysis results. In the face of the complexity of multi-source heterogeneous n...
