- Abstract
- The stay-point extraction is one of major features for analysis with GPS data. Most previous studies considered multiple trajectories and they overlooked revisits in a single trajectory. However, the number of visits for specific location reveals significant semantics of user behavior. Therefore, we proposed the algorithm for stay-point extraction considering revisits and evaluate our method with 21 persons' GPS data in the wild. The metric for stay-points and labels is also proposed in this study.
