MOBILE SOCIAL BEHAVIOR
MOTIVATION AND CHALLENGE
Nowadays, due to the wide use of mobile devices, more and more web applications have been expanded to mobile platforms, as have Online Social Networks services. We believe that it is the right time to highlight the importance of mobile social networks (MSNs). In MSNs, mobile users can publish and share information based on the social connections among them. On one hand, most major Online Social Networks platforms such as Facebook, Twitter, and LinkedIn release mobile applications to allow users to access their services through mobile devices. On the other hand, more mobile-centric functions have been integrated into Online Social Networks, such as location-based services and mobile communication. Understanding the user behavior in MSNs is very helpful for the design and implementation of MSN systems, improving the system efficiency in mobile environments or supporting better mobile-centric functions. In this section, we focus on studies of user behaviors in MSNs.
