[Purpose/significance] The propagation characteristics micro-blog topic was studied based on the time network influence model.[Method/process] This article first constructed micro-blog topic influential network model, and discussed the definition of the influence of the network, the key factor analysis, model and calculate the network weights.On this basis, the proposed model was based on the propagation time of the network influence(Time Network Influence Model).Using SinaWeibomicro-blog platform and data DATAMALL topic, the simulation of dynamic propagation micro-blog topic with the course of time and users' influence strength was studied.[Result/conclusion] The results showed that:about 93.3% of topics delayed within 5 hours;the higher the micro-blog topic's network influence weight, the more the corresponding number of the forwarding comments, and the greater influence of the micro-blog topic.Finally, the model(TNIM) was compared with the traditional influence of the network model(LDA).The results show the influence of the accuracy and stability of the network weights TNIM model are higher than the LDA model, and the effectiveness of the TNIM model is verified.
