Information diffusion on and offline
The advent of massive online social networks has allowed us to map the way in which individuals interact and mutually influence each other. By directly observing what is being shared publicly we can also track how individual pieces of information or memes diffuse along the edges of the network. Using Twitter and Yahoo! Meme as case study we will analyze how the different types of edges in a multiplex networks can play different semantic roles. Finally, by connecting the online world with the offline world through geolocation we will analyze briefly how human mobility and language impact information spread.
