| Abstract: |
| Mining user leader in social network is an important issue for user influence management.In this paper,a user leader mining algorithm in social network based on user influence assessments is proposed,which comprises aspects as follows:firstly,the model of proposed algorithm and its related definitions are described formally;secondly,a user leadership degree evaluation method is presented based on user influence and user activeness calculation;and finally,the user leader mining algorithm is proposed based on two factors of user leadership degree and user centrality.Furthermore,the experimental results show the feasibility and effectiveness of our proposed algorithm. |
| Key words: social network user leader mining user influence activeness centrality |
