Abstract: The era of big data has brought big opportunities to network science, yet the study of network science is also facing big challenges of processing huge amount of data. Meanwhile, a new project outsourcing model, the crowd-sourcing model, has been widely applied recently to solving data related problems. This paper presents a brief introduction to the new driving forces of network science: big data and crowd-sourcing model. We also review the 2013 Alibaba data platform innovation competition as well as our award-winning work. We expect that driven by the crowd-sourcing model, data science, which deals with big data processing techniques, shall evolve together with network science into a prosperous future.
