Application of percolation model in spreading dynamics driven by social networks big data

Spreading dynamics is a common yet sophisticated phenomenon in real life, and percolation theory is widely applied in analysis of this dynamics due to its conciseness and efficiency. With the development of information technology, the quality and quantity of available data are being improved. Although this offers a chance to describe and understand empirical spreading phenomena more comprehensively and accurately, complicated dynamics brought by massive data pose new challenges to the study of social contagion based on percolation theory. In this prospective, we show, by analyzing examples, how the percolation theory is used to describe the information transmission on social networks driven by big data. We also explore the indirect influence mechanism behind the spread of scientific research behavior, and develop a new algorithm to quantify the global influence of nodes from the local topology. Finally, we propose, based on these example studies, several possible new directions of percolation theory in the study of social contagion driven by big data.
