Spatiotemporal Analysis of a Location Based Social Network Dataset based on Different Levels of Granularity - A Study Case of Japan Dataset.

Due to the rapid development of social media networks, as well as the recent advances on smartphone technologies, users stopped being only consumers and became data producers. It enabled a new form of sensing, engaging a variety of studies using Location-Based Social Networks (LBSN) data. For instance, in device-to-device(D2D) communication systems, the user location is required to make mobile data offloading possible. However, getting the right location is a challenging task, and the analyses of LBSN datasets provide large-scale studies at a low-cost. On the other hand, depending the the level of granularity used on the analyses, it may result in the success or failure of the prediction. Therefore, in this paper, we show the importance of combining the different levels of granularities for studying user behavior in order to obtain a robuster analysis.
