Before revision: Groups of small and medium enterprises (SMEs) can back each other to obtain loans from banks and thus form guarantee networks. If the loan repayment of a small company in the network defaults, its backers are required to repay the loan. Therefore, risk over networked enterprises may cause significant contagious damage. In real-world applications,  it is critical to detect top vulnerable nodesin such complex financial network with near real-time performance.
After revision: Uncertain graphs have been widely used to model complex linked data in many real-world applications, it is critical to detect top vulnerable nodesin such complex financial network with near real-time performance.
