Room: Informatics West 105

Abstract: Today’s online social networks and social media sites contain a combination of social and informational ties that serve as bridges for different types of information to flow. An example of such social network is Twitter, where many users follow their friends and others that they are interested in but do not know in real life such as celebrities, news media accounts, and politicians. In this talk, I will discuss different aspects of how these networks form and how information flows through them. I will also show how studying different aspects of network formation and information diffusion on social media sites can be useful for gaining sociological insights as well as improving the sites.
