چکیده
The Study on Maximizing the Spread of Influence through a Social Network has been strongly attracted attentions recently. One of the most important problems is figuring those who are ableto make the strongest influence on the others in spreading information based on a specific topic. We would like to build asystem to support viral marketing on social networks and to promote the topic modeling, the propagation model and propagation algorithm to find out the most influential group of users of each topic. The system consists of several steps, such as word extracting, data processing and finding the most influentialusers in exchanged topics. We especially focus on calculating the users’ influence probabilities via an action log file, using thepropagation model – TLT (Topic-aware Linear Threshold) and the propagation algorithm – CELF (Cost Effective Lazy Forward).Furthermore, we also experiment our model with Enron email data, which includes 11,177 emails exchanged among 147 users and estimated in 50 topics. We have received many useful topics and the most influential group of usersکلیدواژه ها
