Abstract: Users engage in all sorts of activities in various different urban functional zones in different roles. How to infer user roles based on urban functional zones or infer frequent urban functional zones based on user roles is a challenge in the research area of human mobility. This paper builds a mutual inference model for user roles and urban functional zones through extracting context awareness factors from users’ micro-blog, e.g. user ID, check-ins and GPS-coordinates. The experimental results show that the model achieves good performance both on the aspects of user roles inference and urban functional zones inference.

Key words: user roles, functional zones, user mobility, context factors
