We investigated the appropriateness of existing mathematical models for explaining the structure of retweet cascades on Twitter; we investigated how to detect spam accounts on Facebook and other social networks by graph analytics; and finally we investigated how to design pricing schemes for users on a social network when their valuations are influenced by their neighbors in the network.
