Abstract
A device for constructing a hierarchical destination prediction mode includes an extracting unit configured to receive a user's historical location data and extract input data and output data from the user's historical location data. The input data includes a leaving location and associated time for the user and the output data includes an arriving location for the user. A determining unit is configured to determine the user's possible activities of each location and their original probabilities based on the input data and the output data, and to adjust the original activity probabilities based on the user's arriving patterns and leaving patterns. A prediction model obtaining unit is configured to obtain the hierarchical destination prediction model based on the input data and the adjusted probabilities. A high layer of the hierarchical destination prediction model represents activities and their transitions, and a low layer of the model represents locations of the activities.
