At present,when verifying the reliability of connectivity information in large-scale complex network,the time used for verification is long and the error of verification result is large.Meanwhile,the verification efficiency is low and the accuracy of verification result is low.Therefore,a method to verify the reliability of connectivity information in large-scale complex network was proposed.At first,ORDER algorithm was used to simplify large-scale complex network,and then average connectivity of large-scale complex networks after the simplified processing was calculated.Base on the mean value of large-scale complex network connectivity,the connectivity degree of connectivity information in large-scale complex network was calculated.Combining the analytic hierarchy process with the expert investigation method,the reliability evaluation index of connectivity information in large-scale complex network was filtered.In addition,the maximum weight in reliability evaluation index of network connectivity information was calculated through sensitivity coefficients.The connectivity information reliability evaluation model of large-scale complex network was built based on network connectivity information.Compared the results of evaluation model with the setting threshold value,the reliability degree of network connectivity information was proved.Finally,the reliability verification for large-scale complex network connectivity information was completed.Simulation results show that the proposed method has high verification efficiency and high accuracy.
