The dissemination of information in social networks is a process, in which some nodes in the network have a much more significant influence on the extent and speed of the spreading than others. Finding these highly influential spreaders has a great significance in understanding and controlling real world networks, suppressing or amplifying the spreading of information.
We analyse the real-world digital platform lookbook.nu, a social network for fashion bloggers. Using simulations on the observed topology as well as measuring real spreading of information, we evaluate centrality measures as an indicator for the power of spreaders on this particular social network.
Due to the dynamic nature of fashion trends, we find that topological changes of the network may occur on the same timescale as the spreading processes. Thus, we investigate whether established centrality measures apply in the context of such a temporal network.
