Mobile User Trajectory and Profile Mining : A GSM CGI based spatiotemporal trend extraction framework for recommender systems

Recent development in smart devices like Smart phones, Ipad, IPod, PDA's and portable wireless sensors network devices made the mobility data a valuable research field nowadays, where the mobility data can be used for the development of location based services (LBS) like Early warning system, Route prediction, City wide sensing, Mobile marketing, Social networking thorough mobility profile building against user's mobility history. This mobility profile represents user's behavioral patterns, spatiotemporal trends; stay points visit history, habits and context, where stay point information is the basic entity to understand user's trends. Because of its low cost coverage and easy availability GSM Cell Global Identity (CGI) is most appropriate method to be used for user mobility profiling. In this book we focused mainly on the precise mobility profile building thorough trajectory and behavioral pattern mining using the GSM CGI Cell-ID, where all the concerned issues like precise spatial extraction, stay points detection and mobility profiling are addressed properly thorough the proposed framework. The book propose utilization of both spatiotemporal and semantic information.
