Abstract

This paper presents a new information diffusion model that studies the impact of trendy topics on the diffusion process based on content analysis. The suggested model (𝑆𝐼𝑡𝑤𝑅) extends the SIR model by adding the topic weight (𝑡𝑤) that mirrors the topic significance reflected on the infection rate. In which, the new infection rate (𝜆𝑡𝑤 ) will be calculated by multiplying the normal infection rate (𝜆) with the topic weight (𝑡𝑤). An experimental study has been conducted on trendy and non-trendy topics and the results are compared to the classical SIR model. The simulation results of the 𝑆𝐼𝑡𝑤𝑅 model using Mathematica show the early diffusion of the trendy topics. It has been concluded that the number of infected accounts will accelerate within a shorter time due to the impact of the trendy topics. Therefore, the proposed model (𝑆𝐼𝑡𝑤𝑅) better reflects the diffusion process in the presence of trendy topics.
