Abstract

The invention discloses a method and a device for mining seed users in an offline mobile social network. The method comprises the following steps: acquiring data; cleaning the data and extracting required user dimension information; constructing a mobile social network graph according to the transmission records among the users in the acquired data; decomposing the mobile social network diagram into a plurality of connected sub-diagrams; quantifying the transmission weight of the number of times of sending between the user pairs in the communication subgraph; quantifying the position similarity between the user pairs; calculating the influence of the user based on the transmission weight and the position similarity, and sorting; and outputting a sorting result, and setting a node before the obtained sorting rank as a seed user.

Description

technical field [0001] The invention relates to a mobile social network formed by device-to-device communication, in particular to a method for mining seed users in an offline mobile social network. Background technique [0002] With the continuous development of mobile communication technology, people are more and more inclined to use mobile devices represented by mobile phones for socializing and entertainment. On the one hand, more mobile users tend to download online files to their mobile devices to satisfy themselves. On the other hand, users have increasingly rich demands for high-quality mobile services, and at the same time, the requirements for mobile network performance are also constantly improving. This has led to the continuous surge of mobile traffic and the gradual decline of operators' profits. The existing mobile network infrastructure and link capacity in many areas can no longer effectively handle the surge of mobile load. Operator's big challenge. Studi...
