Title : On Understanding Social Propagations
Propagation phenomenon is an important problem that has been studied within varied research fields and application domains, leading to the development of propagation based models and techniques in social informatics. These models are briefly surveyed in this talk. However, there exist many common noteworthy challenges to be addressed for the practical use of this phenomenon such as the increased complexity of social networks, its increasingly dynamic behaviour, the need for continued survival or rapid decline, and permanent threat of potential cascading errors and malicious attacks. This talk discusses common features and two selected scenarios of propagation mechanisms based on symmetric push-pull activity that frequently occur in social networks. In social propagation, investigation of spreading actions, ordering them in time and analysing resilience is very important. Therefore, particular attention is paid to propagation measures: distance, centrality, efficiency and robustness at the step-time interval to help evaluate the process. Finally, a list of the most recent open issues on social propagation is presented.
