报告摘要： With the rapid development of positioning, sensor and smart device technologies, large quantities of human behavioral data are now readily available. They reflect various aspects of human mobility and activities in the physical world. The availability of this data presents an unprecedented opportunity to gain a more in depth understanding of users and provide them with personalized online experience while respecting their privacy. In this talk, I will describe our vision of building a unified user knowledge graph which supplements existing knowledge graphs with information generated from both public and personal user data, e.g. check-in trajectories, mobile communication histories and environmental sensor readings. I will also present our recent research efforts supporting this objective, including user linking across multiple networks, user mobility understanding and prediction, psychological trait inference and life pattern analysis.
