Defining Measures for Location Visiting Preference

For better location based service or better analysis of human mobility pattern, measures for presenting frequently visiting locations are usually required. In this paper, we will establish related measures for specific meaningful locations. Location points as well as Location clusters are objects of the measurements. In order to represent the degree of a specific location visit, the degree of location visit called Position Frequency (PF), and Inverse Location Frequency (ILF) are defined. In order to represent the degree of location area (cluster) visit, Inverse Cluster Frequency (ICF) is established. Moreover, along with the frequency of location visit, the duration of location visit is also considered. Therefore Position Duration (PD), Inverse Location Duration (ILD), and Inverse Cluster Duration (ICD) are defined. Using R language, real positioning data set collected by volunteers are analyzed in order to demonstrate the usefulness of these measures. The definitions of measures and the application of measures will be presented.
