摘要：People travel in the real world and leave their location history in a form of trajectories. These trajec-
tories do not only connect locations in the physical world but also bridge the gap between people and
locations. This paper introduces a social networking service, called GeoLife, which aims to understand
trajectories, locations and users, and mine the correlation between users and locations in terms of user-
generated GPS trajectories. GeoLife offers three key applications scenarios: 1) sharing life experiences
based on GPS trajectories; 2) generic travel recommendations, e.g., the top interesting locations, travel
sequences among locations and travel experts in a given region; and 3) personalized friend and location
recommendation.
