On Mining 2 Step Walking Pattern from Mobile Users

Knowledge extraction from mobile user data analyzes data collected from mobile users, such as their user movement data in order to derive useful knowledge. User movement data is stored in a database which records the (x, y) coordinates that users have visited at any given point of time, for each mobile users. In this paper, we present a novel method for mining 2 step walking pattern from mobile users. The result of 2 step walking pattern provides the knowledge of how mobile users walks from one location of interest (LOI) to another in any given 2 steps. Case study for Walking-Matrix and Walking-Graph are provided along with performance evaluation.
