Online social networks are multi-dimensional and dynamic. By combining these two perspectives, we can differentiate between various temporal patterns, better understand the mechanisms behind network formation, and test theories that are potentially associated with the behaviors of individuals online.

Traditional data mining techniques are going through an extensive research so as to suit their application in the dynamically evolving social media networks which are not only large in size but also require real time processing of data streams.
