| Abstract: | Purpose/significance]In order to deal with the quick birth-death process and unconspicuous hotspot characteristics of information transmission nodes, a new detecting and prognosis system is proposed based on complex networks. Method/process]In order to deal with those problems, a novel micro-blog information transmission hotspot inward node prognosis algorithm was proposed as the IPIN algorithm based on complex network analysis methods. This paper used this algorithm to build a model with complex network node relations, and found relation sub-networks by related nodes. Then, the thermal power spectrum computing was used to dope out information transmission ranges and prospective effects. Result/conclusion]Data experiment results prove that the IPIN algorithm has higher hot transmission node coverage rate, accuracy rate and better cost-performance than those of the SNMA algorithm. |
