Online Social Networks (OSNs) are based over computer systems that should perform under user generated load. It is therefore important to understand how the user behaves in OSNs to evaluate the generated load. However there are various kinds of user behaviors in such services and we are lack of comprehensive studies of various user behaviors. In this thesis we study the user behaviors in OSNs from three points of views, (a) the online contents consumption behavior, (b) the favoring behavior, and (c) the online content production behavior.

Online Social Networks (OSNs) are based over computer systems that should perform under user generated load. It is therefore important to understand how the user behaves in OSNs to evaluate the generated load. However there are various kinds of user behaviors in such services and we are lack of comprehensive studies of various user behaviors. In this thesis we study the user behaviors in OSNs from three points of views, (a) the online contents consumption behavior, (b) the favoring behavior, and (c) the online content production behavior.

First we study the online contents consumption behavior in respect to the popularity of online contents. We model the popularity of online contents with explanatory factors by using the Cox proportional hazard regression model and predict their popularity. Second we investigate the user favoring behaviors, i.e., how users favor other users' contents and how they reciprocally favor their contents. Third, we look into how online users generate their contents in OSNs and specifically we scrutinize their content generation behaviors and model them with the stretched exponential distribution.
